Iridium-Catalyzed Hydroarylation of Conjugated Dienes via π‑Allyliridium Intermediates

A hydroxoiridium/cod complex efficiently catalyzed hydroarylation of conjugated dienes with arenes bearing an acidic N–H bond as a directing group, which can form an amidoiridium species as an active intermediate for C–H activation. A π-allyliridium­(III) complex was isolated as a key intermediate leading to the addition product

Hydroxoiridium-Catalyzed Hydroarylation of Alkynes and Bicycloalkenes with <i>N</i>‑Sulfonylbenzamides

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