Reaction of N-(2,2,2-Trichloroethylidene)arenesulfonamides with aromatic and heterocyclic compounds

N-(2,2,2-Trichloroethylidene)arenesulfonamides react with aromatic and heterocyclic compounds in the presence of oleum to give N-[1-aryl(heteryl)-2,2,2-trichloroethyl]arenesulfonamides.

C-amidoalkylation of aromatic compounds with chloral arylsulfonylimines and derivatives thereof

N-(1-Hydroxy, 1-alkoxy-, 1-acetoxy, 1-arenesulfonamido-2,2,2-trichloroethyl)-arenesulfonamides in the presence of concentrated sulfuric acid behave as active C-amidoalkylating agents, and in reaction with aromatic compounds afford 1-aryl-1-(arenesulfonami
