Abstract

Abstract : An iridium(iii )-catalyzed C–N-bond-forming direct synthesis of carborane azo derivatives was developed. Abstract : An iridium(iii )-catalyzed C–N-bond-forming direct synthesis of carborane azo derivatives was developed. The reaction of o -carborane monocarboxylate with aryldiazonium salt in the presence of a catalytic amount of [Cp*IrCl2 ]2 and NaOAc in CH3 CN at 80 °C gave the corresponding carborane azo derivative in good yield. A series of cyclometalated iridium/rhodium complexes that contain Cp*M–B (M = Ir, Rh) bonds, and are stabilised by the intramolecular coordination of nitrogen donors, were successfully isolated and structurally characterised.
