CO₂ utilization had been drawn environmentally and economically much attention for a long time. Despite extensive researches, searching for the industrially useful catalytic system still remained as an important research area. As a new titanium catalytic system, two new titanium complexes containing tridentate chiral Schiff-base Ligand, L, prepared from condensation reaction with 2,4-pentadione and (1R,2S)-(−)-1-aminoindanol, were synthesized and characterized by various methods inculding X-ray crystallography. The ligand L acted as a dianionic tridentate ligand and had chiral center at amino indanol group, providing chirality to titanium complexes. These complexes were used in the cycloaddition of CO₂ to propylene oxide; both of complexes provided high selectivity of CPC(cyclic propylene carbonate) (>99%) and showed moderate activities compared with the reported catalyst systems.
