A new routine for the synthesis of N-substituted-N-(sulfonyl) bromoacetamides with ZnCl2 as a catalyst

Abstract

A series of N-acylated N-substituted sulfonamides was prepared for the first time in good yields and with excellent conversion by the reaction of N-substituted-N-(p-toluene) sulfonamides (1) with acetyl chloride and bromoacetyl bromide (2), respectively, in the presence of a catalytic amount of anhydrous ZnCl2.
