Hydroxoiridium-Catalyzed Hydroarylation of Alkynes and Bicycloalkenes With N-Sulfonylbenzamides

Hydroxoiridium complexes efficiently catalyzed the hydroarylation of alkynes and bicycloalkenes with N-sulfonylbenzamides via C-H activation to give the corresponding ortho-alkenylation and alkylation products in high yields.
