Reusable Polymer‐Supported Amine‐Copper Catalyst for the Formation of α‐Alkylidene Cyclic Carbonates in Supercritical Carbon Dioxide
Abstract
A green, simple and effective polymer-supported catalytic system has been developed for the cyclization of propargyl alcohols with carbon dioxide (CO2). α-Alkylidene cyclic carbonates were obtained in satisfactory isolated yields in most cases. The catalyst could be recovered by simple filtration and reused several times without significant loss of activity. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
