Abstract

Abstract : Palladium-catalyzed C–H/N–H functionalization of N -alkoxy benzsulfonamides with arynes provides dibenzosultams via C–C/C–N bond formation, accompanied by an unexpected N–O bond cleavage. Abstract : Palladium-catalyzed C–H/N–H functionalization of easily prepared N -alkoxy benzsulfonamides with arynes provides dibenzosultams in good yields via C–C/C–N bond formation, accompanied by an unexpected N–O bond cleavage. A mechanistic study shows that the reaction proceeds through a rate-determining C–H bond cleavage.
