中文摘要：

合成了新颖的双功能水溶性金属卟啉 催化剂 M（TTMAPP）I4（X） （M = Co, Fe, Mn 和 Cr; X = OAc, CF3COO, CCl3COO, OTs, Cl, Br 和 I）, 研究了它们催化 CO2 与末端环氧化合物合成环碳酸酯的偶联反应. 分别考察了反应温度、不同金属的 Lewis 酸中心、抗衡离子和催化剂重复使用次数对反应性能的影响. 当以 Co（III）（TTMAPP）I4（OAc） 为催化剂, 底物与催化剂摩尔比为 1 000, 温度为 353 K, CO2 压力为 667 kPa 和无溶剂条件下, 反应 5 h 时丙烯环碳酸酯收率为 95.4%. 在 298 K, 底物与催化剂之比为 2 000 时, 加入 1 ml 甲醇, 反应 24 h 丙烯环碳酸酯收率为 19.4%. 催化剂可以用乙醚回收, 循环使用 5 次后催化剂活性没有明显降低.

英文摘要：

New catalysts of water soluble bifunctional metalloporphyrins M（TTMAPP）I4（X） （M = Co, Fe, Mn, and Cr; X = OAc, CF3COO, CCI3COO, OTs, C1, Br, and I） were synthesized and used to catalyze the synthesis of cyclic carbonate through the coupling reaction of terminal epoxides and CO2. The effects of reaction temperature, various metals as the Lewis acidic center, counterions, and recycling of the catalysts were studied. 5,10,15,20-Tetra-（p-N,N-trimethylphenyl ammonium iodide）porphyrinium cobalt（III） acetate [Co（III）- （TTMAPP）Ia（OAc）] was efficient in the coupling reaction of various terminal epoxides and CO2 at 353 K under 667 kPa of CO2 pressure without solvent and molar ratio of epoxide：catalyst = 1000. It gave a propylene carbonate yield of 95.4% within 5 h. At 298 K in the presence of 1 ml methanol with the molar ratio of epoxide：catalyst = 2000, it gave a propylene carbonate yield of 19.4% within 24 h. The catalyst could be recovered with diethyl ether and reused five times without significant loss of catalytic activity.
