Ir-Catalyzed Heterocyclization by Benzylic C-H Activation

The reaction is proposed to proceed through the formation of an electrophilic iridium nitrenoid. 

Ir-Catalyzed Silylation of Benzylic Amines and 2,A/-Dialkylanilines via Aryl C-H Bond Activation 

Hartwig reported that the iridium-catalyzed silylation of benzylic amines to afford azasilolane compounds [155]. 

This reaction consists of dehydrogenative silylation of A/ -methylbenzylamine and 2,AT-dialkylamine by hydrosilane involving orf/to-aryl C-H or benzyl C-H bond activation. 

Sames and coworkers reported that the catalytic oxidative cyclization of amide can be achieved by an iridium carbene complex, which consists of [Ir(coe)2Cl]2,
