Abstract

Al(OTf)3 as a recyclable catalyst conducts the efficient conversion of various types of α-hydroxyphosphonates to their corresponding α-trimethysilyloxyphosphonates with HMDS in the absence of solvent at room temperature. The general applicability of the catalyst under solvent-free conditions is demonstrated by applying it for the successful silylation of alcohols and phenols with HMDS in high yields.
