New approach to the preparation of p-(1-cyanoethyl)arenesulfonamides by reaction of arylsulfonyl imines of polychloroacetaldehydes with acetone cyanohydrin

Abstract

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-dichloro-1-cyanoethyl)arenesulfonamides.
