Efficient homogeneous photochemical water gas shift reaction catalysed under extremely mild conditions by novel iridium(III) complexes: [(η5-Me5C5)Ir(bpy)Cl]+, [(η5-Me5C5)Ir(bpy)H]+, and [(η5-Me5C5)Ir(phen)Cl]+(bpy = 2,2′-bipyridine; phen = 1,10-phenanthroline)
Abstract
The title compounds are shown to be active catalysts for the light-driven water gas shift reaction with turnover numbers up to 10 h–1; the iridium hydride species exhibits strong luminescence in solution at room temperature.
