概要 Various oxiranes reacted with carbon dioxide at 100 °C using lithium bromide as a catalyst under atm. pressure to afford the corresponding five-membered cyclic carbonates quant. The rate of the reaction increased as the bulkiness of substituents on the oxirane ring was reduced or an electron-withdrawing group was introduced on the oxirane ring. The stereochem. of the reaction of oxirane and carbon dioxide was retention without loss of optical purity. When substituted phenylethylene carbonates were reacted with benzylamine, the selectivity to afford secondary alc. increased as the electron-withdrawing ability of the para-substituent increased.
