Silanediol-catalyzed carbon dioxide fixation

Abstract

Carbon dioxide is an abundant and renewable C1 source. However, mild transformations with carbon dioxide at atmospheric pressure are difficult to accomplish. Silanediols have been discovered to operate as effective hydrogen-bond donor organocatalysts for the atom-efficient conversion of epoxides to cyclic carbonates under environmentally friendly conditions. The reaction system is tolerant of a variety of epoxides and the desired cyclic carbonates are isolated in excellent yields.

Keywords: carbon dioxide; cyclic carbonate; hydrogen-bond donors; metal-free catalysis; silanediol.
