Rasta Resin-DMAP and its Use as a Recyclable Catalyst for the Addition of Carbon Dioxide to Epoxides

摘要

Rasta resin-DMAP, a new heterogeneous polystyrene-based amine, has been synthesized and used as a catalyst in addition reactions of carbon dioxide to epoxides to afford cyclic carbonate products. This new material was found to be a more efficient cata-lyst than divinyl benzene cross-linked polystyrene-supported DMAP, and was readily recovered and reused without significant loss of catalytic activity.
