In 2019,Chemical Science included an article by Liu, Gongyi; Zhang, Heng; Huang, Yi; Han, Zhengyu; Liu, Gang; Liu, Yuanhua; Dong, Xiu-Qin; Zhang, Xumu. Product Details of 625-99-0. The article was titled 《Efficient synthesis of chiral 2,3-dihydro-benzo[b]thiophene 1,1-dioxides via Rh-catalyzed hydrogenation》. The information in the text is summarized as follows:
Rh-catalyzed asym. hydrogenation of prochiral substituted benzo[b]thiophene 1,1-dioxides was successfully developed, affording various chiral 2,3-dihydrobenzo[b]thiophene 1,1-dioxides I (R = H, 6-MeO; R1 = C6H5, 4-MeOC6H4, 4-FC6H4, etc.; R2 = C6H5, 4-MeOC6H4, 3-H3CC6H4, etc.) with high yields and excellent enantioselectivities (up to 99% yield and >99% ee). In particular, for challenging substrates, such as aryl substituted substrates with sterically hindered groups and alkyl substituted substrates, the reaction proceeded smoothly in catalytic system with excellent results. The gram-scale asym. hydrogenation proceeded well with 99% yield and 99% ee in the presence of 0.02 mol% (S/C = 5000) catalyst loading. The possible hydrogen-bonding interaction between the substrate and the ligand may play an important role in achieving high reactivity and excellent enantioselectivity. The experimental process involved the reaction of 1-Chloro-3-iodobenzene(cas: 625-99-0Product Details of 625-99-0)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Product Details of 625-99-0Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution.
