The photocatalyzed synthesis of silanols from tertiary silanes has been carried out using eosin Y under air. This is a metal-free method that uses a low catalyst loading, atmospheric oxygen as the oxidant, and visible-light conditions (blue light).
使用曙红 Y 在空气中进行了由叔硅烷光催化合成硅烷醇。这是一种无金属方法,使用低催化剂负载、大气中的氧气作为氧化剂和可见光条件(蓝光)。

Triarylsilanols have been reported as the first silicon-centered molecular catalysts for direct amidation of carboxylicacids with amines as identified after a screen of silanols, silanediols, disiloxanediols, and incompletely condensed silsesquioxanes as potential homogeneous catalysts. Subsequent synthesis and testing of various electronically differentiated triarylsilanols have identified tris(p-haloaryl)silanols
