A facile, one-pot synthetic method to prepare alkoxo-functionalized homoleptic cyclometalated Ir (III) compounds with facial geometry has been developed. The reaction of Ir(COD)2BF4 with two bipyridine ligands, 2′,6′-dimethoxy-4-methyl-2,3′-bipyridine and 2′,6′,4-trimethoxy-2,3′-bipyridine, afforded the homoleptic Ir (III) compounds Ir[(RO)2(Me)pypy]3 (1) and Ir[(RO)3pypy]3 (2) in good yields. The reaction
