摘要：

The carbonylation of methanol with carbon monoxide to dimethyl oxalate and dimethyl carbonate in the presence of palladium(II) acetate has been shown to be influenced by the ligands, the CO pressure and added base. With phosphines, the ligand influence appears to be related mainly to their electronic properties. Alkylphosphines inhibit carbonylation almost completely. Low CO pressures and the presence of tertiary amines enhance the formation of dimethyl carbonate. A scheme accounting for these findings is presented. © 1979.
