The synthesis of a representative number of N(1)-substituted N(2)-iodomethylsulphonylbenzamidines is reported, together with the new general synthesis of N(1)N(3)-disubstituted N(2)-sulphonylguanidines by the interaction of sulphonamides and carbodi-imides in the presence of base. The base-induced ring closure of these iodomethylsulphonyl compounds has been shown to provide a route to 3-aryl- and
