The synthesis of a unique heterogeneous catalyst that combines the functionality of a homogeneous catalyst and the advantages of a heterogeneous catalytic process is a continuing goal in various industrially applicable reactions. Here, we report heterogenization of homogeneous catalyst for lactone production from epoxide carbonylation through a facile polymerization using Friedel–Crafts reaction. A correlation between reactivity and degree of heterogeneity has been deduced by synthesizing different sized polymeric catalysts. The partially polymerized catalyst showed a remarkable initial turnover frequency of 400 h–1, and the fully polymerized catalyst displayed excellent selectivity during recycling with a total turnover number of 4100.

卟啉钴酸铬催化环扩环羰基化成β-内酯的非均质性与反应性之间的平衡
结合了均相催化剂的功能性和非均相催化方法的优点的独特非均相催化剂的合成是各种工业适用反应中的持续目标。在这里，我们报道了通过使用Friedel-Crafts反应的轻松聚合，由环氧化物羰基化生产内酯的均相催化剂的均相化。通过合成不同尺寸的聚合物催化剂已经推导了反应性和非均相程度之间的相关性。部分聚合的催化剂显示出显着的400 h –1的初始周转频率，而完全聚合的催化剂在循环期间显示出极好的选择性，总周转数为4100。
