Synthesis of hydrido–iridium(III) complexes from a trifluoromethanesulphonato intermediate

Abstract

The versatile new precursor to bis-2,2′-bipyridine complexes of IrIII, cis-[IrIII(bpy)2(OSO2CF3)2][CF3SO3](bpy = 2,2′-biyridine), has been isolated and used for the preparation of the new hydrido complexes of IrIII, cis-[Ir(bpy)2(PPh3)H][PF6]2 and cis-[Ir(bpy)2H2][PF6], and for an improved, high-yield synthesis of [Ir(bpy)3][PF6]3.
