Syntheses of various 2-oxazolidinones/2-imidazolidinones were carried out using polyethylene glycol functionalized phosphonium salt as an efficient homogenous recyclable catalyst via sequential addition of CO2, different epoxides and amino alcohols/alkylene diamines. The effects of various reaction parameters such as temperature, reaction time and catalyst concentration were investigated in detail. The catalyst was readily separated and reused. Excellent yields of 2-oxazolidinones/2-imidazolidinones and higher conversion of cyclic carbonates were observed.
