Reactions of N,N,N ', 4,Ndichlorobenzenesulfonamide), and 4, with 1,2-dichloroethylene and trichloroethylene open convenient synthetic approach to highly electrophilic bissulfonylimines of dichloroacetic aldehyde and chloral: N,N'-bis(polychloroethylidene)biphenyl-4,4'-disulfonamides, 4,4'-methylenebis[N-(polychloroethylidene)benzenesulfonamides] and 4,4'-oxybis[N-(polychloroethylidene)benzenesulfonamides]. The synthetic opportunities of the bisazomethines obtained were demonstrated by examples of their reactions with water, methanol, chloroacetamide, and toluene where products of O-, N-nucleophiles addition to the azomethine bond and products of C-amidoalkylation of aromatic compound with imines were formed.
