The copper(I)-borohydride complex [(triphos)Cu(BH4)] reacts with CO2, CS2, and COS under very mild conditions to give formate, dithioformate, or thioformate copper(I) complexes, respectively. A complete X-raycrystalstructure determination has been carried out on the formate complex [(triphos)Cu(O2CH)].

hydrogenation of CO2 to formate, reacts with H2 in the presence of a base to form a cationic dicopper hydride, [(LCu)2H]PF6. [(LCu)2H](+) is also an active precursor for catalytic CO2 hydrogenation, with equivalent activity to that of LCu(MeCN)(+), and therefore may be a relevant catalytic intermediate. The thermodynamic hydricity of [(LCu)2H](+) was determined to be 41.0 kcal/mol by measuring the equilibrium
