Brownson, G. W. published the artcileFar-infrared intensity and normal coordinate studies on pyridine-halogen complexes, SDS of cas: 6443-90-9, the publication is Journal of Molecular Structure (1971), 10(1), 147-53, database is CAplus.

Absolute integrated intensity data were determined for the 2 low frequency bands due to ν(D-I) and ν(I-X) in pyridine-IX (X=I, Cl, Br) complexes. Along with the normal coordinates, calculated by using a linear triat. model, these data were used to calculate dipole derivatives * vecμ/* j values. Pyridine-d5-IBr spectra were used to estimate possible values of the interaction force constant k13. The dipole moment change * vecμ/* D-I calculated for the pyridine-I2 complex by using a simple model is considerably lower than that observed, implying that charge-transfer effects contribute significantly to the band intensities.

Wang, Zhuo published the artcile4-Aminobenzotriazole (ABTA) as a removable directing group for palladium-catalyzed aerobic oxidative C-H olefination, SDS of cas: 638-45-9, the publication is Organic Letters (2022), 24(17), 3107-3112, database is CAplus and MEDLINE.

4-Aminobenzotriazole (ABTA) was applied as an effective removable directing group (DG) in Pd-catalyzed C-H activation for the first time. Compared with the widely applied pyridine and quinoline analogs, ABTA showed significantly improved reactivity, achieving aerobic oxidative C-H olefination in excellent yields (up to 95% vs <50% with other reported DGs under identical conditions). Using this new strategy, macrocyclization was achieved to give cyclic peptides in good yields with easy ABTA removal under mild conditions, highlighting the promising potential of this new DG.

Wang, Xiao-Xu published the artcileNiH-catalyzed reductive hydrocarbonation of enol esters and ethers, Recommanded Product: 1-Iodohexane, the publication is CCS Chemistry (2022), 4(2), 605-615, database is CAplus.

Chiral dialkyl carbinols and their derivatives are significant synthetic building blocks in organic chem. and related fields. The development of convenient and efficient methods to access these compounds has long been an important endeavor. Herein, authors report a NiH-catalyzed reductive hydroalkylation and hydroarylation of enol esters and ethers. α-Oxoalkyl organonickel species were generated in situ in a catalytic mode and then participated in cross-coupling with alkyl or aryl halides. This approach enabled C(sp3)-C(sp3) and C(sp3)-C(sp2) bond formation under mild reductive conditions with simple operations, thereby boosting a broad substrate scope and good functional compatibility. Esters of enantioenriched dialkyl carbinols were accessed in a catalytic asym. version. Mechanistic studies demonstrated that this reaction proceeded through a syn-addition of Ni-H intermediate to an enol ester with high regio- and enantioselectivity.

Guo, Yongxian published the artcileForce-Induced Molecular Isomerization for the Construction of Multicolor Luminescent Segmented Molecular Crystals, Related Products of iodides-buliding-blocks, the publication is Advanced Optical Materials (2022), 10(2), 2101794, database is CAplus.

Multicolor luminescent segmented materials have attracted tremendous research interest due to their potential applications as barcoding materials in information security and anti-counterfeiting. Although much effort has been devoted to the preparation of photonic barcodes based on different light-emitting materials, the rational design of barcoding materials with well-controlled emission color and length at desired position remains a challenge. Here, a novel strategy to fabricate multicolor luminescent segmented 1D mol. crystals is reported by manipulating the mol. conformation and intermol. interactions of the mechanochromic crystals, which are assembled from a rationally designed twisting conjugated mol. The emission color of these mechanochromic crystals changes from green to orange with the mechanism of synergy effect of force-induced mol. isomerization from trans to cis state and mol. packing changes from cross to parallel, which is revealed by single crystal X-ray diffraction. Multicolor luminescent segmented 1D microribbons are fabricated by applying precisely controlled forces by tapping mode at. force microscope, which shows the encoding capability. These findings provide a new method that allows the controllable fabrication of segmented materials with tunable emission color and length at desired position toward barcoding applications.

A copper-catalyzed alkoxycarbonylation transformation of unactivated alkyl iodides was developed. Various alkyl iodides were converted into the corresponding tert-Bu esters in good yields. NaOt-Bu acts as both a nucleophile and a base. Moreover, other types of aliphatic esters was also be obtained in moderated yields if extra alcs. are added. Both primary and secondary alkyl alcs. can react successfully.

Wu, Fu-Peng published the artcileCopper-Catalyzed Borylative Methylation of Alkyl Iodides with CO as the C1 Source: Advantaged by Faster Reaction of CuH over CuBpin, Application In Synthesis of 638-45-9, the publication is Angewandte Chemie, International Edition (2021), 60(21), 11730-11734, database is CAplus and MEDLINE.

CuH and CuBpin are versatile catalysts and intermediates in organic chem. However, studies that involve both CuH and CuBpin in the same reaction is still rarely reported due to their high reactivity. Now, a study on CuH- and CuBpin-catalyzed borylative methylation of alkyl iodides with CO as the C1 source is reported. Various one carbon prolongated alkyl boranes (RCH₂Bpin and RCH(Bpin)₂) were produced in moderate to good yields from the corresponding alkyl iodides (RI). In this cooperative system, CuH reacts with alkyl iodide faster than CuBpin.
