"One-pot" synthesis of carbamates via curtius rearrangement

Abstract

In this thesis, acyl chlorides were successfully converted to their corresponding carbamates via Curtius rearrangement in a novel one-pot synthesis procedure that uses p-nitrobenzenesulfonylazide as the azide nucleophile source. In the process alkyl esters were also synthesized as the associated by-product. The thesis also deals with the one-pot synthesis of acyl azides from acyl chlorides.
