Abstract

The transmetalation reaction of a chiral-bidentate NHC-silver complex to racemic [Ir(mu-Cl)(ppy)(2)](2) operates with kinetic resolution leading to chiral octahedral NHC-iridium(III) complexes and enantioenriched bis-cyclometalated iridium(III) complexes. The iridium(III) complexes demonstrated efficient catalytic activities in intermolecular [2+2] photocycloaddition reactions and in asymmetric Friedel-Crafts alkylations, respectively.
