Green synthesis of cyclic carbonates: Magnesium(II)/phosphine complexes are developed for the synthesis of cyclic carbonates through the coupling of epoxides and carbon dioxide. Various cyclic carbonates are prepared in excellent yields under extremely mild, solvent-free conditions at relatively low temperatures and pressures. The catalyst system shows excellent recyclability, and the cyclic carbonates can be separated easily.
