反応手順
A mixture of 7.03 g (0.05 g mole) of benzoyl chloride, 4.5 g (0.05 g mole) of dimethyl carbonate, and 0.85 g (0.0025 g mole) of tetra-n-butyl phosphonium bromide (TBPB) in 25 ml of sulfolane was heated at 150° C. in a reaction flask equipped with reflux condenser. After 22 hours, the condenser was replaced by a distillation head and 6.3 g (93 percent yield) of methyl benzoate distilled at 83° C.-85° C./17 mm.
