corresponding complexes Ti(L1)2(NMe2)2 (1) and Ti(L2)2(NMe2)2 (2), respectively. The titaniumcomplexes 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
