Reaction of 4-methoxy-N,N-dichlorobenzenesulfonamide with trichloroethylene and phenylacetylene underlies an effective method developed for the synthesis of highly reactive 4-methoxy-N-(2,2,2-trichloroethylidene)- and 4-methoxy-N-(2,2-dichloro)-2-phenylethylidene)benzenesulfonamides, valuable reagents for the preparation of new difficultly accessible derivatives of the sulfonamide series.
