a Chemical structures of selected amine promotors utilized in formate dehydrogenation and bicarbonate hydrogenation. b Hydrogen production from formate in the presence of various amines. Standard conditions: KHCO2 (10 mmol), amine (10 mmol), Fe-1 (5 μmol), THF/H2O (5/5 mL), 90 °C, 16 h. Yields are based on KHCO2. c Hydrogenation of bicarbonate in the presence of various amines. Standard conditions: KHCO3 (10 mmol), amine (10 mmol), Fe-1 (5 μmol, 500 ppm), THF/H2O (5/5 mL), H2 (60 bar), 90 °C, 12 h. Yields are based on KHCO3.
