| Abstract: | The coupling reaction of carbon dioxide with epoxides were investigated using naturally occurring α-amino acids as catalyst in supercritical carbon dioxide and it was found that L-histidine is the most active catalyst. In the presence of 0.8 mol% of histidine at 130 °C under 8 MPa of CO2, the reaction of carbon dioxide with epoxides proceeded effectively and afford corresponding cyclic carbonates in good to excellent yields. |
