Comparative bindings of several renowned monomers were investigated experimentally using B(C6F5)3 as a Lewis acid model for the coordination step in ring-opening polymerization. A complete series of the X-ray crystal structures of the B(C6F5)3 adducts with the monomers was reported. The X-raystructuralstudies and spectroscopic data revealed a coordination strength in the order lactones > tetrahydrofuran
使用B(C 6 F 5)3作为路易斯酸模型进行开环聚合的配位步骤,实验研究了几种著名单体的比较键合。报道了B(C 6 F 5)3与单体的加合物的完整系列的X射线晶体结构。X射线结构研究和光谱数据揭示了内酯>四氢呋喃>环状碳酸酯>丙交酯的配位强度。
