Reactions of N-(2,2-dichloro-2-phenylethylidene)arenesulfonamicles with aromatic and heterocyclic compounds

Benzene, toluene, and 2-chlorothiophene regioselectively react with N-(2,2-dichloro-2-phenylethylidene)arenesulfonamides in the presence of oleum to give N-[1-aryl(or hetaryl)-2,2-dichloro-2-phenylethyl]arenesulfonamides. Analogous C-amidoalkylation products are formed by the action of N-(2,2-dichloro-1-hydroxy-2-phenylethyl)- and N-(1-arylsulfonylamino-2,2-dichloro-2-phenylethyl)arenesulfonamides on toluene and 2-chlorothiophene in concentrated sulfuric acid.
