Procedure

A mixture of 7.83 g (0.05 mole) of phenyl chloroformate, 2.48 g (0.0275 mole) of dimethyl carbonate, and 0.85 g of TBPB was heated at 150° C. under a reflux condenser for 4 hours when all gas evolution had ceased. Distillation of the reaction mixture gave 5.25 g (98 percent yield based on chloroformate) of diphenyl carbonate.
