Reactions of internally metallated tris(triphenylphosphine)iridium(I) complex with carbon monoxide, hydrogen and methanol

Abstract

The reaction of the internally metallated tris(triphenylphosphine)iridium (I) complex with CO, H 2, CH 3OH in solution gives rise to a new - carbonyl,hydridocarbonyl and hydrido complexes of iridium(I) and iridium(III). The preparation and characterization of these compounds are reported. A new route to prepare the pure isomers fac- and mer-[(C 6H 5) 3P] 3IrH 3 is also described. The stereochemistries of the products have been assigned by a combination of IR and 1H NMR spectroscopy.
