✦ Synopsis

Abstract

A mild, simple, novel and highly efficient method for the rapid protection of various primary, secondary, tertiary aliphatic and aromatic alcohols using hexamethyldisilazane (HMDS) in the presence of N‐bromosuccinimide (NBS) as an active, inexpensive, non‐toxic and readily available catalyst under solvent‐free conditions is described. Trimethylsilyl ethers were prepared in high to excellent yields with short reaction time under mild and almost neutral reaction conditions.
