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

Abstract

Rasta resin-DMAP, a new heterogeneous polystyrene- based amine, has been synthesized and used as a catalyst in addi- tion reactions of carbon dioxide to epoxides to afford cyclic car- bonate products. This new material was found to be a more effi- cient catalyst than divinyl benzene cross-linked polystyrene sup- ported DMAP, and was readily recovered and reused without significant loss of catalytic activity.
