Reactions of propargylic alcohols with CO(2) in a [BMIm][PhSO(3)]/CuCl catalytic system to produce the corresponding alpha-methylene cyclic carbonates were conducted with high yields. Mild reaction conditions, enhanced rates, improved yields, and recyclable ionic liquid catalyst systems are the remarkable features exhibited in this process. Furthermore, the use of large amounts of tertiary amines as well as nitrogen-containing organic solvent as employed in previously studies was avoided.
在[BMIm][PhSO₃]/CuCl催化体系中，炔丙醇与二氧化碳反应生成相应的α-亚甲基环状碳酸酯，产率很高。温和的反应条件、加快的反应速率、提高的产率以及可循环使用的离子液体催化剂体系是该过程展现出的显著特点。此外，避免了先前研究中使用大量叔胺以及含氮有机溶剂的情况。
