Title: CO 2 Hydrogenation Catalysts with Deprotonated Picolinamide Ligands

In an effort to design concepts for highly active catalysts for the hydrogenation of CO 2 to formate in basic water, we have prepared in this paper several catalysts with picolinic acid, picolinamide, and its derivatives, and we investigated their catalytic activity. The CO 2 hydrogenation catalyst having a 4-hydroxy-N-methylpicolinamidate ligand exhibited excellent activity even under ambient conditions (0.1 MPa, 25 °C) in basic water, exhibiting a TON of 14700, a TOF of 167 h –1, and producing a 0.64 M formate concentration. Finally, its high catalytic activity originates from strong electron donation by the anionic amide moiety in addition to the phenolic O functionality.
