A monoselective synthesis of aryl-C-Δ1,2-glycosides, e.g. I, from 1-iodoglycals via palladium-catalyzed ortho-C-H activation of N-quinolyl benzamides has been developed. An amino acid derivative was used as a crucial ligand to improve the yield and monoselectivity of the coupling reaction. The utility of this protocol was demonstrated by a concise synthesis of key moieties of some natural products.1,2-Diiodoethane(cas: 624-73-7Reference of 1,2-Diiodoethane) 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.Reference of 1,2-Diiodoethane

The potential of (2-bromoethyl)diphenylsulfonium triflate to be a powerful vinylation reagent was determined by the Sonogashira cross-coupling reactions with terminal alkynes RCCH (R = Ph, thiophen-3-yl, 4,4-dimethyl-3,4-dihydro-2H-1-benzothiopyran-6-yl, etc.). The vinylation proceeded smoothly at 25°C under Pd/Cu catalysis to afford a variety of 1- and 2-unsubstituted 1,3-enynes RCCCH=CH2 in moderate to excellent yields. This protocol represents the first application of (2-haloethyl)diphenylsulfonium triflates X(CH2)2S+(C6H5)2.-OTf (X = Br, F, OTs) and 5-(2-bromoethyl)-5H-thianthren-5-ium triflate as a CH=CH2 transfer source in organic synthesis.

In 2016,Zhang, Wei; Tan, Yue Hua; Finch, James A. published 《Synthesis and characterization of alkyl, propoxy, ethoxy-based frothers》.Minerals Engineering published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

In this paper the authors describe the synthesis and characterization of a homologous series of linear polyglycol-based frothers comprising alkyl, propoxy (propylene oxide, PO), and ethoxy (ethylene oxide, EO) groups. The identities were confirmed by proton NMR spectroscopy and total organic carbon anal. Characterization used three parameters, bubble size, gas holdup and water overflow rate, measured in a bubble column. The results indicate that increasing number of PO groups led to significant decrease in bubble size, and increase in gas holdup and water overflow rate. Increasing the alkyl chain length, gave similar but less pronounced trends; the least effect was increasing the number of EO groups. Changing the relative position of the PO and EO group had a significant effect on all three parameters. To account for the effect of PO/EO position, a mechanism based on effect of structure on mol. packing at the air/water interface is proposed.

Hyeok published 《Bis-imidazolium iodide organic ionic plastic crystals and their applications to solid state dye-sensitized solar cells》.Organic Electronics published the findings.Safety of 1,2-Diiodoethane The information in the text is summarized as follows:

Novel dicationic bis-imidazolium iodide salts have been discovered as new organic ionic plastic crystalline materials. Most of them show multiple solid-solid phase transitions below their melting temperatures Their phase transition temperatures are dependent on the imidazolium cation structure. According to Timmermans’ definition of plastic crystals, bis-imidazolium iodide salts with either n-heptyl or n-octyl side arms can be classified as “”true plastic crystals”” because of their low ΔSf values (<20 J mol-1 K-1). The bis-imidazolium iodide salts are stable up to 260°C under thermal gravimetric anal. The ionic conductivities, investigated using dielec. relaxation spectroscopy, follow the Arrhenius temperature dependence with discontinuities and changes in slopes at the observed solid-solid phase transition temperature Dye-sensitized solar cells (DSSCs) fabricated by a whole solid-state electrolyte consisting of n-hexyl side-armed bis-imidazolium iodide (BII-6) show a 4.93% power conversion efficiency (η): a remarkable result for the solid-state electrolyte system compared to that obtained using an liquid electrolyte with 1-butyl-3-methylimidazolium iodide (η = 8.00%) as a reference composition1,2-Diiodoethane(cas: 624-73-7Safety of 1,2-Diiodoethane) was used in this study.

《Estimated Survival and Major Comorbidities of Very Preterm Infants Discharged Against Medical Advice vs Treated With Intensive Care in China.》 was written by Jiang, Siyuan; Huang, Xiangyuan; Zhang, Lan; Han, Junyan; Yang, Yi; Wang, Weiping; Lee, Shoo K; Yan, Weili; Cao, Yun; Reduction of Infection in Neonatal Intensive Care Units Using the Evidence-Based Practice for Improving Quality (REIN-EPIQ) Study Group. Safety of 1,2-Diiodoethane And the article was included in JAMA network open in 2021. The article conveys some information:

Importance: A significant proportion of very preterm infants (<32 weeks' gestation) are discharged against medical advice (DAMA) from neonatal intensive care units in China. There is minimal information available on the potential outcomes of providing complete care before discharge in these infants. Objective: To describe potential neonatal outcomes of DAMA in very preterm infants if they receive complete care based on estimates derived from a group of propensity score-matched infants who are not DAMA. Design, Setting, and Participants: This cohort study enrolled all infants born at between 24 and 31 weeks' gestation from May 1, 2015, to April 30, 2018, and admitted to 25 tertiary neonatal intensive care units across China within 7 days of birth. A multilevel mixed-effects logistic regression model was constructed to estimate the propensity score for the likelihood of DAMA for each infant. Infants who were not DAMA were then matched to DAMA infants with the closest propensity score on a 1:1 ratio by using a nearest neighbor greedy matching algorithm without replacement. Incidences of neonatal outcomes were then calculated among the matched non-DAMA infants to simulate the outcomes of DAMA infants. Statistical analyses were performed from August 16, 2020, to September 26, 2020. Exposures: Discharge against medical advice, which was defined as termination of treatment and discharge before the treating physicians recommended discharge. Main Outcomes and Measures: Survival and survival without major morbidity. Results: The study enrolled a total of 14 083 infants (8141 boys [57.8%]) with a median gestational age of 30.1 weeks (interquartile range [IQR], 29.0-31.1 weeks) and a median birth weight of 1400 g (IQR, 1170-1600 g). Overall, 1876 of 14 083 very preterm infants (13.3%; 95% CI, 12.8%-13.9%) were DAMA, of whom 1367 of 1876 (72.9%; 95% CI, 70.8%-74.8%) required intensive care on discharge. A total of 1473 DAMA infants were successfully matched to 1473 non-DAMA infants. Overall, 1211 of 1473 matched non-DAMA infants (82.2%; 95% CI, 80.2%-84.1%) survived to discharge. The survival rates were 68.3% (95% CI, 62.4%-73.7%) for infants at 26 to 27 weeks' gestation, 84.1% (95% CI, 80.7%-87.0%) for infants 28 to 29 weeks' gestation, and 92.4% (95% CI, 90.0%-94.2%) for infants at 30 to 31 weeks' gestation. A total of 872 of 1473 matched non-DAMA infants (59.2%; 95% CI, 56.7%-61.7%) survived without any major morbidity. Conclusions and Relevance: The results of this cohort study suggest that very preterm infants who are DAMA from neonatal intensive care units may have intact survival if complete care is provided. Efforts to reduce DAMA may be associated with improved outcomes of very preterm infants in China.

A new mild C-C bond forming cyclization approach of catechol derivatives is reported. This approach relies on an initial dearomatization step using lead(IV) acetate followed by a carefully controlled radical cyclization step, which under the reaction conditions also facilitates rearomatization. Triethylborane is key to the success of this reaction as it enables the reaction to proceed at low temperatures and is also believed to aid rearomatization. The amount and ratio of triethylborane and reducing agent (tributyltinhydride) that is employed as well as the concentration the reaction is run at are all essential to the success of this new approach.1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 624-73-7) was used in this study.

In 2017,Ikai, Tomoyuki; Suzuki, Daisuke; Shinohara, Ken-ichi; Maeda, Katsuhiro; Kanoh, Shigeyoshi published 《A cellulose-based chiral fluorescent sensor for aromatic nitro compounds with central, axial and planar chirality》.Polymer Chemistry published the findings.Category: iodides-buliding-blocks The information in the text is summarized as follows:

Chiral sensing using fluorescent responses as output signals is an attractive technique for enantiodifferentiation in terms of its rapidity, high sensitivity, simplicity and high-throughput ability. However, because the reported sensors can only be applied to a limited type of chiral mol. (mainly compounds with a chiral center), it is still a great challenge to develop a powerful fluorescent sensor applicable to various types of chirality. Herein, we synthesized a novel chiral fluorescent sensor (Ce-3) containing a benzo[1,2-b:4,5-b]dithiophene-based π-conjugated group as a fluorescent signaling unit through a two-step polymer reaction, including carbamoylation and cross-coupling reactions, using microcrystalline cellulose as a starting material. The enantioselective fluorescence response of this modified cellulose to aromatic nitro compounds was investigated in solution and in the solid state. Ce-3 exhibited enantioselective fluorescence quenching for a wide range of aromatic nitro compounds with central, axial and planar chirality. Visual chiral detection based on a change of the visible emission color was also achieved with Ce-3 in conjunction with anthracene as an achiral fluorescent dye. A corresponding model mol. did not show any marked sensing ability, suggesting that the regular higher-order structure of Ce-3 plays a key role in this efficient chiral sensing. The results came from multiple reactions, including the reaction of 1,2-Diiodoethane(cas: 624-73-7Category: iodides-buliding-blocks)
