In 2016,Castello-Mico, Alicia; Herbert, Simon A.; Leon, Thierry; Bein, Thomas; Knochel, Paul published 《Functionalizations of Mixtures of Regioisomeric Aryllithium Compounds by Selective Trapping with Dichlorozirconocene》.Angewandte Chemie, International Edition published the findings.Recommanded Product: 624-73-7 The information in the text is summarized as follows:

The reaction of mixtures of aryllithium regioisomers obtained either by directed lithiation or by Br/Li exchange with substoichiometric amounts of Cp2ZrCl2 proceeds with high regioselectivity. The least sterically hindered regioisomeric aryllithium is selectively transmetalated to the corresponding arylzirconium species leaving the more hindered aryllithium ready for various reactions with electrophiles. As an application, these regioselective transmetalations from Li to Zr were used to prepare all three lithiated regioisomers of 1,3-bis(trifluoromethyl)benzene. In the experiment, the researchers used many compounds, for example, 1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 624-73-7)

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.

SDS of cas: 624-73-7In 2018 ,《Broadly Applicable Stereoselective Syntheses of Serrulatane, Amphilectane Diterpenes, and Their Diastereoisomeric Congeners Using Asymmetric Hydrovinylation for Absolute Stereochemical Control》 was published in Journal of the American Chemical Society. The article was written by Tenneti, Srinivasarao; Biswas, Souvagya; Cox, Glen Adam; Mans, Daniel J.; Lim, Hwan Jung; RajanBabu, T. V.. The article contains the following contents:

A stereogenic center, placed at an exocyclic location next to a chiral carbon in a ring to which it is attached, is a ubiquitous structural motif seen in many bioactive natural products, including di- and triterpenes and steroids. Installation of these centers was a long-standing problem in organic chem. Few classes of compounds illustrate this problem better than serrulatanes and amphilectanes, which carry multiple methyl-bearing exocyclic chiral centers. Nickel-catalyzed asym. hydrovinylation (AHV) of vinylarenes and 1,3-dienes such as 1-vinylcycloalkenes provides an exceptionally facile way of introducing these chiral centers. This Article documents our efforts to demonstrate the generality of AHV to access not only the natural products but also their various diastereoisomeric derivatives Key to success here is the availability of highly tunable phosphoramidite Ni(II) complexes useful for overcoming the inherent selectivity of the chiral intermediates. The yields for hydrovinylation (HV) reactions are excellent, and selectivities are in the range of 92-99% for the desired isomers. Discovery of novel, configurationally fluxional, yet sterically less demanding 2,2′-biphenol-derived phosphoramidite Ni complexes (fully characterized by x-ray) turned out to be critical for success in several HV reactions. We also report a less spectacular yet equally important role of solvents in a metal-ammonia reduction for the installation of a key benzylic chiral center. Starting with simple oxygenated styrene derivatives, we iteratively install the various exocyclic chiral centers present in typical serrulatane [e.g., a (+)-p-benzoquinone natural product, elisabethadione, nor-elisabethadione, helioporin D, a known advanced intermediate for the synthesis of colombiasin and elisapterosin] and amphilectane [e.g., A-F, G-J, and K,L pseudopterosins] derivatives A concise table showing various synthetic approaches to these mols. is included in the Supporting Information. Our attempts to synthesize a hitherto elusive target, elisabethin A, led to a stereoselective, biomimetic route to pseudopterosin A-F aglycons.1,2-Diiodoethane(cas: 624-73-7SDS of cas: 624-73-7) was used in this study.

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.SDS of cas: 624-73-7

In 2015,Zhang, Hua; Wang, Caixia; Jiang, Tao; Guo, Haiming; Wang, Ge; Cai, Xinhua; Yang, Lin; Zhang, Yi; Yu, Haichuan; Wang, Hui; Jiang, Kai published 《Microtubule-Targetable Fluorescent Probe: Site-Specific Detection and Super-Resolution Imaging of Ultratrace Tubulin in Microtubules of Living Cancer Cells》.Analytical Chemistry (Washington, DC, United States) published the findings.Category: iodides-buliding-blocks The information in the text is summarized as follows:

Tubulins in microtubules have been recognized as potential targets in cancer chemotherapy for several years. However, their detection and imaging in living cells, especially following exposure to anticancer drugs, remains difficult to achieve. This difficulty is due to the very small cross section of microtubules and the very small changes in tubulin concentration involved. Photoswitchable fluorescent probes combined with the “”super-resolution”” fluorescence imaging technique present an exciting opportunity for site-specific detection and super-resolution imaging of specific microscopic populations, such as tubulin. A tubulin specific photoswitchable fluorescent probe (Tu-SP), that labels and detects ultratrace levels of tubulin in microtubules of living biosystems, was designed and evaluated. To realize super-resolution fluorescence imaging, the spiropyran derivative (SP), a classic photoswitch, was introduced to Tu-SP as a fluorophore. To detect ultratrace tubulin, Tu-SP employed the tubulin inhibitor, alkaloid colchicine (Tu), as a recognition unit. Tu-SP exhibited nearly nonintrinsic fluorescence before binding to tubulin, even if there were divalent metal ions and 375 nm lasers, resp. After binding to tubulin, a dramatic increase in fluorescence was detected within milliseconds when irradiated at 375 nm, this increase is a result of the transformation of Tu-SP into a colored merocyanine (Tu-SP-1) with fluorescence. Tu-SP was successfully used for site-specific imaging of tubulin at a resolution of 20 ± 5 nm in microtubules of living cancer cells. More importantly, the probe was suitable for site-specific and quant. detection of trace tubulin in microtubules of living biol. samples.

In 2019,Journal of the American Chemical Society included an article by Bendelsmith, Andrew J.; Kim, Seohyun Chris; Wasa, Masayuki; Roche, Stephane P.; Jacobsen, Eric N.. Formula: C2H4I2. The article was titled 《Enantioselective Synthesis of α-Allyl Amino Esters via Hydrogen-Bond-Donor Catalysis》. The information in the text is summarized as follows:

Chiral-squaramide-catalyzed enantio- and diastereoselective synthesis of α-allyl amino esters is reported. The optimized protocol provides access to N-carbamoyl-protected amino esters via nucleophilic allylation of readily accessible α-chloro glycinates. A variety of useful α-allyl amino esters were prepared, including crotylated products bearing vicinal stereocenters that are inaccessible through enolate alkylation, with high enantioselectivity (up to 97% ee) and diastereoselectivity (>10:1). The reactions display 1st-order kinetic dependence on both the α-chloro glycinate and the nucleophile, consistent with rate-limiting C-C bond formation. Computational anal. of the uncatalyzed reaction predicts an energetically inaccessible iminium intermediate, and a lower energy concerted SN2 mechanism.

In 2015,Gonzalez-de-Castro, Angela; Xiao, Jianliang published 《Green and Efficient: Iron-Catalyzed Selective Oxidation of Olefins to Carbonyls with O2》.Journal of the American Chemical Society published the findings.Related Products of 624-73-7 The information in the text is summarized as follows:

A mild and operationally simple iron-catalyzed protocol for the selective aerobic oxidation of aromatic olefins to carbonyl compounds is described. Catalyzed by a Fe(III) species bearing a pyridine bisimidazoline ligand at 1 atm of O2, α- and β-substituted styrenes were cleaved to afford benzaldehydes and aromatic ketones generally in high yields with excellent chemoselectivity and very good functional group tolerance, including those containing radical-sensitive groups. With α-halo-substituted styrenes, the oxidation took place with concomitant halide migration to afford α-halo acetophenones. Various observations have been made, pointing to a mechanism in which both mol. oxygen and the olefinic substrate coordinate to the iron center, leading to the formation of a dioxetane intermediate, which collapses to give the carbonyl product. Safety: all oxidation reactions should be carried out with caution due to potential fire and explosion hazards.

In 2022,Minemoto, S.; Mun, J. H.; Teramoto, T.; Yagishita, A.; Tsuru, S. published an article in Journal of Electron Spectroscopy and Related Phenomena. The title of the article was 《Ultrafast X-ray photoelectron diffraction from free molecules: Simulations of diffraction profiles from transient intermediates in the elimination reaction of C2H4I2》.Application of 624-73-7 The author mentioned the following in the article:

We have performed the simulations of C 1 s X-ray photoelectron diffraction (XPD) profiles from C2H4I2, bridged and classical anti-forms of C2H4I intermediates and C2H4 products to capture structures of transient intermediates in the elimination reaction of C2H4I2, under our ultrafast X-ray photoelectron diffraction (UXPD) scheme for free mols. using soft X-ray free-electron laser (SXFEL). In the UXPD scheme, the sample mols. are aligned in advance by near-IR (NIR) laser with ns pulse duration before applying a pump – probe method. Then, we have considered alignment control of C2H4I2 by using the elliptically polarized NIR laser to realize the UXPD experiments for the free mols. As the results of simulations of XPD profiles from the laser-aligned C2H4I2 mols., we have demonstrated the two-dimensional (2D) color maps of the C 1 s XPD profiles from C2H4I2, C2H4I, and C2H4. The 2D color maps have revealed that the transient C 1 s XPD profiles from the bridged-form and classical anti-form C2H4I intermediates exhibit remarkable differences, reflecting different intra-mol. scattering pathways of C 1 s photoelectrons within the intermediates. Thus, the present result has proved that UXPD for the free mols. has an advantage, compared with other traditional diffraction methods.

The kinetic energy of ions produced by a Coulomb explosion, in which multiply charged mol. cations dissociate, is determined by the charge number, mass, and geometric configuration of the ions upon explosion. Although the importance of the structural deformation and migration of atoms on kinetic energy variations is well known, there has been little investigation into the effect of charge localization before the ions are released. In this study, the angular distributions of iodine and carbon ions ejected from linear alkanes, which have one iodine atom on each side of an alkyl chain having one to six carbon atoms, are measured. The highly charged iodine ions (I4+, I5+) are emitted mostly along the laser polarization direction, whereas the angular distribution of iodine ions becomes isotropic the longer the alkyl chain and the lower the charge number of iodines are. Furthermore, the longer the alkyl chain, the higher the kinetic energy of iodine and carbon ions. The emission of ions is discussed in terms of the selective ionization of aligned mols. based on their MOs. The charge localization during ionization in strong alternating elec. fields followed by two-body Coulomb explosion via a C-I bond cleavage is proposed.

《Essential oils constituents, phytochemical analyses, and antimicrobial studies on leaf and stem of Thunbergia laevis Nees》 was written by Olaoluwa, Olaoluwa Omosalewa; Moronkola, Dorcas Olufunke; Kwenga, Sichilongo; Mgbeoji, Okwu. COA of Formula: C2H4I2This research focused onThunbergia leaf stem essential oil phytochem antimicrobial. The article conveys some information:

Essential oils of leaf and stem of Thunbergia laevis were obtained by Clevenger-type apparatus, their chem. constituents were analyzed using gas chromatog. [GC] and gas chromatog.-mass spectrometry [GC-MS]. Hexane and ethanol extracts from leaf and stem of Thunbergia laevis were obtained by cold extraction and screened for phytochem. constituents. Antimicrobial activities of these oils, hexane and ethanol extracts were carried out against six bacteria and four fungi. Forty-six compounds identified in leaf oil account for 62.58% of it, dominated by phytol (4.10%) and i-Pr hexadecanoate (3.19%); ten compounds in stem oil represent 62.40% of it, with most abundant methoxyl-phenyl-oxime (23.45%) and Z-11- hexadecenoic acid (12.28%). Leaf oil mostly contains hydrocarbons and esters, while stem oil have aromatic derivatives and acids. Antimicrobial studies of leaf oil caused strong inhibition in growth of Staphylococcus aureus and Candida albicans at concentration between 25 – 100% with the zone of inhibition ranging between 20 -28 mm and 14 – 18 mm resp. Stem oil was most active on Candida albicans and Asprgillus niger at the same concentration with zone of inhibition of 14 – 18 mm and 12 – 18 mm resp. Alkaloids, tannins, saponins, resins, phenols and terpenoids were observed in leaf and stem ethanol extracts Leaf ethanol extract was most active on Staphylococcus aureus, Candida albicans and Rhizopus stolonifer. Stem ethanol extract moderately inhibited growth of these microorganisms. This study is on Thunbergia laevis leaf and stem essential oils constituents, phytochem. and antimicrobial analyses, which have not been earlier reported in literature.

In 2015,Guo, Haiquan; Liu, Fangfang; Zhao, Jianying; Yao, Haibo; Jin, Rizhe; Kang, Chuanqing; Bian, Zheng; Qiu, Xuepeng; Gao, Lianxun published 《In situ iodoalkane-reduction of graphene oxide in a polymer matrix: an easy and effective approach for the fabrication of conductive composites》.Journal of Materials Chemistry C: Materials for Optical and Electronic Devices published the findings.Related Products of 624-73-7 The information in the text is summarized as follows:

In situ chem. reduction (ISCR) of graphene oxide (GO) dispersed in a polymer matrix has been regarded as an effective path to fabricate elec. conductive graphene/polymer composites due to the combination of perfect dispersion of GO in a polymer matrix and high elec. conductivity of graphene. However, there are only very limited number of reducing agents that can be applied to the ISCR process for the fabrication of graphene/polymer composites. Herein, we report a highly efficient reducing agent, 1,2-diiodoethane, which can be used in the preparation of graphene (IGO)/polyimide (PI) composites via the ISCR process. The results showed that the elec. conductivity of IGO/PI composites with 2.5 wt% of IGO was 2.22 S m-1, nearly seven orders of magnitudes higher than that of GO/PI without the addition of 1,2-diiodoethane. Moreover, the tensile strength and modulus of IGO/PI composites were increased by about 43% and 52% as compared with that of the pure PI, resp. Furthermore, 1,2-diiodoethane and its decomposition products would not remain in the composites. The ISCR-based methodol. can be extended to many other polymer composites and thus paves the way for easy and effective fabrication of conductive polymer composites.
