“…The traditional methods to prepare silanols heavily rely on the hydrolysis of chlorosilanes or alkoxysilanes, but with limited substrate scope, poor selectivity and low yields. 7 Alternatively, direct oxidation of hydrosilanes was considered as a straightforward and promising route to access silanols. However, stoichiometric strong oxidants such as permanganate, peroxy acid, dioxirane, silver nitrate, and osmium oxide are normally involved.…”
