Short communication: Silica sulfuric acid: A versatile and reusable heterogeneous catalyst for the synthesis of N-ACYL carbamates and oxazolidinones under solvent-free conditions

Abstract

Silica sulfuric acid catalyzes efficiently the reaction of carbamates and oxazolidinones with anhydrides under solvent-free conditions. All the reactions were done at room temperature and the N-acyl carbamates and oxazolidinones were obtained with high yields and purity via an easy work-up procedure. This method is attractive and is in a close agreement with green chemistry. © 2011 Chemical Society of Ethiopia.
