corresponding complexes Ti(L1)2(NMe2)2 (1) and Ti(L2)2(NMe2)2 (2), respectively. The titanium complexes were fully characterized by NMR measurement and elemental analysis as well as the single-crystal X-ray diffraction of 1 and 2. Both 1 and 2 exhibit high activities towards intermolecular hydroamination of terminal alkynes with high selectivity, and they also efficiently promote the ring-opening polymerization
配体 2-pyrazol-1-yl-1H-indole (HL1) 和 2-1,2,4-triazol-1-yl-1H-indole (HL2) 在四氢呋喃中分别与 Ti(NMe2)4 反应形成相应的配合物分别为 Ti(L1)2(NMe2)2 (1) 和 Ti(L2)2(NMe2)2 (2)。钛配合物通过 NMR 测量和元素分析以及 1 和 2 的单晶 X 射线衍射进行了充分表征。 1 和 2 均表现出高选择性对末端炔烃的分子间加氢胺化的高活性,并且它们也有效地促进ε-己内酯的开环聚合。
