triazolium halide units were synthesized as bifunctional catalysts for kinetic resolution of epoxides with CO2. Several catalysts were screened by changing the linker length and nucleophilic counteranions, and the optimized catalyst accelerated the enantioselective reaction at ambient temperature to produce optically active cyclic carbonates and epoxides.
合成了具有卤化三唑鎓单元的手性联萘联的Zn(II)卟啉作为双功能催化剂,用于动力学拆分CO 2的环氧化物。通过改变接头长度和亲核抗衡阴离子筛选了几种催化剂,优化的催化剂在环境温度下加速了对映选择性反应,从而生成了光学活性的环状碳酸酯和环氧化物。
