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.

N-Chloro-N-(2,2,2-trichloro-1-acetoxyethyl)arenesulfonamides are formed with high yields in the reaction of β,β-dichlorovinyl acetate with N,N-dichloroarenesulfamidines.They readily exchange the acetoxy group for alkoxy, alkylthio, and alkylamino groups (
