Abstract

Abstract: A porphyrin based catalytic system with three metals of Manganese, Zinc and Iron and quaternary ammonium salt as co‐catalyst showed very high selectivity for CO2 fixation reaction of different epoxide monomers for synthesizing cyclic carbonates. The reaction showed quantitative yields under solvent‐free and atmospheric pressure. Quaternary ammonium salts were able to catalyse these reactions singlehandedly, thus their mole ratios were decreased to investigate metalloporphyrins effect. After three cycles of reusing, this catalytic system showed minor reduction in activity and no weight loss. Also, manganese porphyrin has high ability to convert bifunctional epoxides (yield 98% in 4h) and vegetable oil by CO2 (yield 99% in 30h) to cyclic carbonates at ambient condition.
