Toward utilizing CO2 as a carbon source for the generation of liquid fuels and other value-added chemicals using renewable energy, the development of chemical transformations for the preparation of multicarbon products is desirable. CO reductive coupling chemistry has been demonstrated with Mo supported by multidentate terphenyl diphosphine ligands. Low temperature synthetic, kinetics, and isotopic labeling studies have been performed to gain mechanistic insight into CO activation and coupling. An intermediate metal carbide intermediate is instrumental for coupling chemistry. In addition to outer sphere electron transfer, sequential proton and hydride transfers have been demonstrated to promote C-C coupling chemistry to generate ketene. The formation of C3 species has been demonstrated. Mechanistic implications will be discussed.
