CO2与环氧化合物制备生物降解材料一直是实现CO2资源化利用的有效途径。近年来越来越多的科技工作者致力于开发高效的均相、非均相催化剂以及调控反应条件以控制反应的选择性,从而获得性能优异的目标产物,目前相关方面的综述较少。文中综述了国内外关于CO2与环氧化物在产物选择性、区域选择性、光学选择性3个方面的研究现状、进展及发展动向。并重点指出CO2与环氧化物在反应过程中催化剂配体、反应温度、压力以及助催化剂的使用对反应在选择性方面的影响规律。
The preparation of biodegradable materials with CO2 and epoxy compounds has been an effective way to achieve the resource utilization of CO2. In recent years, more and more scientists are devoted to developing highly efficient homogeneous and heterogeneous catalysts and controlling the reaction conditions to control the selectivity of the reaction so as to obtain the target product with excellent performance. In this paper, the research status, progress and development trends of CO2 and epoxides at home and abroad are reviewed in terms of product selectivity, regioselectivity and optical selectivity. The influence of catalyst ligand, reaction temperature, pressure and cocatalyst on the reaction selectivity in the reaction of CO2 with epoxides was also pointed out.
