CH2=SMe2), in the presence of CO2 (1 atm) bubbled sequentially under mild conditions, produces cyclic carbonates in preparative yields. Sodiumiodide formed in situ promotes the reaction between epoxide as intermediate and CO2 at ambient conditions, thus constituting a powerful metal-free synthesis of organic cyclic carbonates directly from aldehydes.
在温和条件下连续鼓泡的 CO2 (1 atm) 存在下,用硫叶立德(CH2=SOMe2 或 CH2=SMe2)处理醛,以制备收率生成环状碳酸酯。在环境条件下,原位形成的碘化钠促进了作为中间体的环氧化物与 CO2 之间的反应,从而构成了直接由醛类强有力的无金属有机环状碳酸酯合成。
