摘要: A catalyst system for direct synthesis of diphenyl carbonate by oxidative carbonylation phenol was investigated with special emphasis on the inorganic redox cocatalyst component. Besides cocatalyst, composed a Pd catalyst, an organic base and drying agent. Ce(OAc)3·H2O found to be most efficient giving DPC in 76% yield turnover number 250 without producing any major side products.
