Salen-Cu(II)@MIL-101(Cr) as an efficient heterogeneous catalyst for cycloaddition of CO2 to epoxides under mild conditions

The composite catalyst Salen-Cu(II)@MIL-101(Cr) was synthesized by “ship in a bottle” method, which demonstrated excellent catalytic activity toward cycloaddition of CO2 to propylene oxide under ambient conditions.77
