Abstract
N,N-Dichlorosulfonamides react with trichloroethylene and 1,2-dichloroethylene at a temperature not exceeding 20°C to afford unstable addition products, N-chloro-N-(1,2,2,2-tetrachloroethyl)- and N-chloro-N-(1,2,2-trichloroethyl)sulfonamides. The latter undergo elimination of chlorine on heating, irradiation, or prolonged storage to give the corresponding N-(2,2-di- or 2,2,2-trichloroethylidene)arene(or trifluoromethane)sulfonamides.
