主　　题：diphenyl carbonate synthesis heterogeneous catalyst palladium complex oxidative carbonylation 

摘      要：A novel complex Pd（C4H2O4）（C4H8N2）0.5 has been synthesized by solvent thermal synthesis and used as a heterogeneous catalyst for direct synthesis of diphenyl carbonate （DPC） by oxidative carbonylation of phenol. In the reaction system of Pd（C4H2O4）（C4H8N2）0.5/Cu（OAc）2/ tetrabutylammonium bromide/ hydroquinone/ 4A molecular sieves, the effect of reaction temperature, time and CO pressure on catalytic activity were investigated, and the results revealed that the catalyst could catalyze oxidative carbonylation of phenol effectively. Under suitable reaction conditions of T=90℃, t=4 h, p（O2）=0.3 MPa, p（CO）=3.9 MPa and CH2Cl2 as solvent, the turnover number （TON） of diphenyl carbonate can reach about 13.50 （mol-DPC/mol-Pd）, which is higher than the TON for oure PdCl2 under the same reaction conditions.
