Abstract
Pd complexes with diimine ligands were investigated as novel Pd catalysts f or direct synthesis of diphenyl carbonate by oxidative carbonylation of phe nol using carbon monoxide and air. Best efficiency was obtained by using a PdCl2(ArN=CH-)(2) or PdCl2(ArN=CMe-)(2)/Mn(TMHD)(3)/(Ph3P=)(2)NBr system wh ere TOF reached 8.08 and 8.00 mol-DPC/mol-Pd h, respectively. The efficienc y was increased with increases in the CO pressure.
