PEG-SO3H as a New, Highly Efficient and Homogeneous Polymeric Catalyst for the Synthesis of Acylals from Aldehydes and Acetic Anhydride

Abstract

A highly e cient, simple and rapid method for the chemoselective preparation of acylals from aldehydes and acetic anhydride in the presence of a catalytic amount of poly(ethylene glycol)-bound sulfonic acid (PEG-SO3H) (1.67 mol%) at room temperature is described. Ketones do not react under these reaction conditions.
