Hydrogenation of CO2 to formic acid with iridiumIII(bisMETAMORPhos)(hydride): the role of a dormant fac-IrIII(trihydride) and an active trans-IrIII(dihydride) species

Author affiliations

Abstract

An IrIII-monohydride species bearing a chemoresponsive ligand is active in catalytic CO2 hydrogenation to formic acid with DBU as the exogenous base. Spectroscopic and computational data reveal a trans-IrIII-dihydride as the essential catalytic intermediate and an IrIII(H)3 species as the dormant off-cycle product. This insight will aid future design of improved CO2 reduction catalysts.
