A mild and highly efficient approach has been developed for the one-pot synthesis of dimethyl carbonate (DMC) from epoxide, carbon dioxide, and methanol under low initial pressure. The key to the successful transformation is the use of a bicomponent catalytic system composed of a hydroxyl-functionalized ionic liquid and an alkali carbonate. This bicomponent catalytic system demonstrated excellent reusability in four runs. Under the optimal reaction conditions, a 64% yield of DMC from propylene oxide and an 81% yield of DMC from ethylene oxide were obtained.
已开发出一种温和且高效的方法，用于在低初始压力下由环氧化物、二氧化碳和甲醇一锅法合成碳酸二甲酯（DMC）。成功转化的关键是使用由羟基官能化离子液体和碱金属碳酸盐组成的双组分催化体系。该双组分催化体系在四次运行中表现出优异的可重复使用性。在最佳反应条件下，环氧丙烷合成DMC的产率为64%，环氧乙烷合成DMC的产率为81%。
