Abstract: A rhodium-catalyzed enantioselective ring-opening/acylation of silafluorenes is reported. The newly developed bulky phosphoramidite ligand, in combination with methanol as the additive, enabled the reaction to create one axial chirality and one silicon-stereogenic center in a… read more here.

DOI: 10.1055/a-1503-7976
Abstract: A Rh-catalyzed enantioselective intermolecular dehydrogenative Si–O coupling of dihydrosilanes with alcohols and silanols is demonstrated. Rh(I) catalyst equipped with a Josiphos ligand enables the highly enantioselective alcoholysis process of dihydrosilanes, giving access to a variety… read more here.
