The reduction has been effected by using a variety of Pd (palladium)-based catalysts. The typical procedure was to suspend 0.25 g of catalyst in 25 cc of an aqueoussolution of sodium bicarbonate purged slowly with hydrogen gas. The sodium formate concentration was followed by withdrawing aliquots for formate determination by /sup 13/C, /sup H/NMR. The reduction may be quite rapid; an initial rate
Carbon Dioxide Radical Anion by Photoinduced Equilibration between Formate Salts and [<sup>11</sup>C, <sup>13</sup>C, <sup>14</sup>C]CO<sub>2</sub>: Application to Carbon Isotope Radiolabeling
emergence of carbondioxideradicalanion chemistry might set forth potential unexplored opportunities. Based on a dynamic isotopic equilibration between formate salts and [13C, 14C, 11C]CO2, C-labeled radicalanion CO2•– could be accessed under extremely mild conditions within seconds. This methodology was successfully applied to hydrocarboxylation and dicarboxylation reactions in late-stage carbon isotope
