Arylsulphamoyl azides. An improved synthesis of chlorosulphonyl azide and its reaction with arylamines
Abstract
Chlorosulphonyl azide can be made safely and efficiently by the reaction of sodium azide with sulphuryl chloride in acetonitrile. The effect of the solvent and catalysts on the reaction is discussed. The reaction of solutions of chlorosulphonyl azide with several arylamines has been studied, and the synthetic utility of the procedure as a source of arylsulphamoyl azides evaluated.
