Anotācija N-Sulfonylcarboxamides can act as both a directing group for C–H activation and an internal oxidant in the Ru-catalyzed annulation reaction with alkynes to give isoquinolones. Of all of the N-sulfonylcarboxamides that were studied, the N-(2,6-difluorophenyl)sulfonamide derivatives were found to be the most efficient and led to the formation of an unstable sulfinate byproduct that decomposed into 1,3-difluorobenzene under the reaction conditions. The described isoquinolone synthesis provides an alternative to the currently known traceless annulations of hydroxamic acid and sulfoximine derivatives.
