摘要

Oxidation of silanes into silanols using water/air has attracted considerable attention,The known methods with no exception required a metal catalyst.Herein we report the first metal-free method:2 mol％ Rose Bengal as the catalyst,air (O2) as the oxidant,water as the additive and under visible light irradiation.While this method produces various silanols in a simple,costeffective,efficient (92％-99％ yields) and scalable fashion,its reaction mechanism is very different than the reported ones associated with metal catalysis.
