Abstract
The present invention provides a process for olefin metathesis. The process comprises (a) providing a reaction mixture comprising an olefin, a metathesis initiator, and a reaction medium comprising carbon dioxide, and (b) reacting the reaction mixture to provide a metathesis modified olefin. The olefin metathesis reaction may be an olefin metathesis exchange reaction, an olefin metathesis degradation reaction, or a metathesis polymerization reaction. The carbon dioxide medium may be liquid, supercritical, and gaseous carbon dioxide.
