Yuan, Wei; You, Lijun; Lin, Weidong; Ke, Jie; Li, Yingzi; He, Chuan published their research in Organic Letters in 2021. The article was titled 《Asymmetric Synthesis of Silicon-Stereogenic Monohydrosilanes by Dehydrogenative C-H Silylation》.Recommanded Product: (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole The article contains the following contents:
An asym. synthesis of silicon-stereogenic monohydrosilanes, e.g. I, by rhodium-catalyzed dehydrogenative C-H silylation is developed. The process is suitable for the synthesis of various asym. trisubstituted 1H-benzosiloles and 1H-benzosilolometallocenes in good yields with excellent chemo-, regio-, and stereocontrol. These selected silicon-stereogenic 1H-benzosilole compounds exhibit bright blue fluorescence and CPL (circular polarized luminescence) signals, which could be attractive to practitioners of materials science. The results came from multiple reactions, including the reaction of (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole(cas: 210169-54-3Recommanded Product: (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole)
(S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole(cas: 210169-54-3) is a chelating ligand used to prepare coordination complex catalysts, such as its use in Pd catalysts for the enantioselective synthesis of spiro- or benzofused hetereocycles with exocyclic olefins via enantioselective intramolecular dearomative Heck reaction of indoles, benzofurans, pyrroles and furans.Recommanded Product: (S)-5,5′-Bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole
