Catalytic activity of metal organic framework Cu3(BTC)2 in the cycloaddition of CO2 to epichlorohydrin reaction

We demonstrate the novel, catalytic activity of metal organic framework of Cu3(BTC)2 catalysts in the synthesis of chloropropene carbonate from CO2 and epichlorohydrin. The catalysts display moderate epoxide conversions, and moderate selectivities to chloropropene carbonate at 100 °C. No solvents or co-catalysts were required. It is suggested that Lewis acid copper (II) sites in the Cu3(BTC)2 framework promoted the adsorption of carbon dioxide on the solid surface and its further conversion to the carbonate.
