Titanocene dichloride (Cp 2 TiCl 2 )/KI was developed to be an efficient catalytic system for the cycloaddition of CO 2 to epoxides to synthesize relevant cyclic carbonates from epoxides and CO 2 . Various influencing factors on the coupling reaction , such as co‐catalyst, temperature, CO 2 pressure and reaction time, were investigated. The optimal reaction conditions were KI as co‐catalyst, 150 °C reaction temperature, 12 atm CO 2 pressure and 4 h reaction time using THF as solvent for the synthesis of propylene carbonate in 98% yield.
