The discovery of the heretofore unobtainable sulfamoyl chloride, NH2S02C1, by Graf, prompted us to investigate the applications of this novel sulfamoylating agent. The first part of this paper details the reactions of sulfamoyl chloride with aromatic amines, leading in one series to a novel heterocyclic system. The second portion is concerned with the mechanism and kinetic study of an unusual cleavage of a sulfamide. This aspect has been utilized in ...
