The reaction of N,N-dichlorobenzenesulfonamide with 2,2-dichlorovinyl ketones leads to 1:1 adducts C6H5SO2NClCH(COR)CCl3.In these adducts the N-Cl bond is converted by the action of atmospheric moisture into an N-H bond with the formation of N-(2,2,2-trichloro-1-acylethyl)benzenesulfonamides.The latter form 2,4-dinitrophenylhydrazones and during treatment with a solution of alkali eliminate hydrogen chloride with the formation of previously unknown N-(2,2-dichloro-1-acylvinyl)benzenesulfonamides.In reaction with thiourea N-benzenesulfonamide forms 2-amino-4-(2,2,2-trichloro-1-benzenesulfonamidoethyl)-1,3-thiazole.
