Aluminium Triflate [Al(OTf)₃] as a Recyclable Catalyst for the Conversion of α-Hydroxyphosphonates, Alcohols and Phenols to Their Corresponding O-Silylated Products with Hexamethyldisilazane (HMDS)

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.

Keywords

α-hydroxyphosphonates - solvent-free - aluminium triflate - α-acetyloxyphosphonates - alcohols - phenols
