Reaction of N-(2,2,2-trichloroethylidene)- or N-(1-phenyl-2,2-dichloroethylidene)arenesulfonamides with acetone cyanohydrin in acetone in the presence of potassium carbonate led to the formation of N- (2,2,2-trichloro-1-cyanoethyl)- or N-(2-phenyl-2,2-dic

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.

The reaction of N,N-dichloro- and N,N-dibromobenzenesulfonamides with phenylacetylene leads to benzenesulfonyliminodichlorophenylacetaldehyde.The latter enters into nucleophilic addition with water, ethanol, benzoic and acetic acids, and amides at the azomethine bond, and N-(2,2-dichloro-2-phenyl-1-R-ethyl)benzenesulfonamides are obtained.
