• bicomponent cocatalyst
• synergistic effect
• oxidative carbonylation

A new catalytic system, which consists of Pd(OAc)(2) as the catalyst and W-Mo-containing heteropolyacids (HPAs)/Mn(OAc)(2) as the bicomponent cocatalysts, has been found to be very efficient in the oxidative carbonylation of phenol to diphenyl carbonate at low pressure in the absence of solvent. The efficiency of the catalytic system is dependent on the ratio of W/Mo in the HPAs, being best in a ratio of 6/6. The synergistic effect between W-Mo-containing HPAs and Mn(OAc)(2) has been observed in the catalysis.
