An efficient, metal-free catalytic system for the conversion of CO2 and epoxides to cyclic carbonates under mild conditions with good-to-excellent yields (57-99%) was developed. A possible reaction mechanism involving the electrophilic activation of epoxides by benzyl cations and nucleophilic activation of CO2 by DMF is proposed.
开发了一种高效的无金属催化体系，可在温和条件下将二氧化碳和环氧化物转化为环状碳酸酯，产率良好至优异（57-99%）。提出了一种可能的反应机理，涉及苄基阳离子对环氧化物的亲电活化以及N,N-二甲基甲酰胺对二氧化碳的亲核活化。
