A new, general synthesis of N-benzoyl-2-arylethenesulfonamides by the reaction of aryl halides including heteroaryl halides with [2-(benzoylsulfamoyl)ethyl]pyridinium chloride in the presence of palladium acetate is described.

A series of vinyl sulfonamides was synthesized using the Horner reaction of aldehydes and diphenylphosphorylmethanesulfonamide. The sulfonamide reagent was easily prepared and can be stored indefinitely. The trans orientation about the double bond of the vinyl sulfonamides was the only isomer observed.
