Abstract
Bimetallic aluminum(salen) complexes were prepared and used as catalyst for the synthesis of DPC from CO2 and phenol in the presence of carbon tetrachloride. The bimetallic complex derived from 3,5-ditert salicylaldehyde and 1,2-cyclohexanediamine revealed more excellent activity than that obtained in the presence of other complexes and the simple Lewis acid ZnCl2. The influence of the amount of complex and the reaction conditions including the pressure of CO2 and the reaction temperature was also investigated.
