Trimethylsilylation of Alcohols and Phenols using KBr as an Efficient and Reusable Catalyst

Abstract

KBr acts as an efficient and reusable catalyst for the selective and efficient trimethylsilylation of benzylic, primary and secondary aliphatic alcohols and phenols with hexamethyldisilazane. All reactions were performed at room temperature under mild and completely heterogeneous conditions in good to high yields.
