Synthesis of N -(2,2-Dichlorovinyl)arenesulfonamides by Dehydrochlorination of N -(2,2,2-Trichloroethyl)arenesulfonamides

Preparation method was developed for N-(2,2-dichlorovinyl)-N-alkylarenesulfonamides based on dehydrochlorination of the corresponding N-(2,2,2-trichloroethyl)-N-alkylarenesulfonamides.
