Abstract

Abstract An unprecedented transfer silylation of alcohols catalyzed by the strong Lewis acid B (C 6 F 5) 3 is described. Gaseous Me 3 SiH is released in situ by B (C 6 F 5) 3-catalyzed decomposition of 3-trimethylsilylcyclohexa-1, 4-diene and subsequently reacts with an alcohol in a dehydrogenative Si–O coupling promoted by the same boron catalyst. Benzene and dihydrogen are formed during the reaction, but no salt waste is. This expedient ...
