With a catalyst loading as low as 0.005%, high to excellent yields of isocyanurates could be achieved from N-heterocyclic olefin mediated organocatalytic cyclotrimerization of a wide range of isocyanates under bulk conditions. Experimental details coupled with structural characterization of the key intermediates led to comprehensive mechanistic studies of cyclotrimerization.
在 0.005%的低催化剂负载量下，通过 N-杂环烯烃介导的各种异氰酸酯的本体条件下的有机催化环三聚反应，可以得到高至优异的异氰尿酸酯产率。实验细节以及关键中间体的结构表征促成了对环三聚反应的全面机理研究。
