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

The direction of alkaline hydrolysis of N-(2,2,2-trichloro-1-R-ethyl)arenesulfonamides depends on the R substituent in the α-position with respect to the nitrogen atom. Substituents R having an n-donor heteroatom X promote cleavage of the C-N and C-X bonds to release the corresponding sulfonamide. Alkaline hydrolysis of N-(1-aryl-2,2,2-trichloroethyl)arenesulfonamides occurs chemoselectively at the trichloromethyl group. This reaction can be regarded as a preparative route to N-arylsulfonyl-α-arylglycines.
Transformations of N-(2,2,2-Trichloroethylidene)-arenesulfonamides
Drozdova,Mirskova
, p. 1330 - 1336 (2007/10/03)
N-(2,2,2-Trichloroethylidene)arenesulfonamides take up at the double C=N bond benzyl and 2-propynyl alcohols and aromatic and unsaturated aliphatic carboxylic acids to give N-(2,2,2-trichloroethyl)-arenesulfonamides. Reactions of the title compounds with dibasic acids (oxalic, succinic, and adipic) result in formation of 1:1 and 2:1 addition products.
C-amidoalkylation of aromatic compounds with chloral arylsulfonylimines and derivatives thereof

The reaction of N,N-dichloroarenesulfonamides with trichloroethylene in the presence of ionic catalyst (SnCl4 and AlCl3) leads to N-(2,2,2-trichloroethyliden)-arenesulfonamides and the products of the subsequent conversion, namely, N-(2,2,2-trichloro-1-arenesulfonamidoethyl)arenesulfonamides and N-(2,2,2-trichloro-1-hydroxyethyl)arenesulfonamides.
