摘要

Direct synthesis of diphenyl carbonate (DPC) from phenoxide, CO 2 and CCl 4 in one pot was realized with ZnCl 2 as catalyst. Trichloromethyl cation may act on potassium phenyl carbonate, which brings the carbonyl more easily attached on by the phenoxide. Onium salts promote the reaction greatly, especially with phenol and potassium carbonate instead of phenoxide as reactants. Moreover, the substituent on the aromatic ring has significant ...
