Description:
The ligands 2-pyrazol-1-yl-1H-indole (HL1) and 2- 1 , 2 , 4 -triazol-1-yl-1H-indole (HL2) individually reacted with Ti(NMe 2 ) 4 in tetrahydrofuran to form the corresponding complexes Ti(L1) 2 (NMe 2 ) 2 ( 1 ) and Ti(L2) 2 (NMe 2 ) 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 of ϵ-caprolactone.
