There is widespread interest in the hydrogenation of CO₂ to energy-rich products such as formate. However, first-row transition metal catalysts for the hydrogenation of CO₂ to formate remain rare. Copper complexes are widely used in the reduction of organic substrates, but their use in the catalytic hydrogenation of CO₂ has been limited. Here, we demonstrate that the copper(I) complex LCu(MeCN)PF₆ is an active catalyst for CO₂ hydrogenation in the presence of a suitable base. Screening of bases and studies of catalytic reactions by in operando spectroscopy revealed important and unusual roles for the base in promoting H₂ activation and turnover.
