Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than … Meer weergeven The reaction requires metal catalysts. Most commercially important processes employ heterogeneous catalysts. The heterogeneous catalysts are often prepared by in-situ activation of a metal halide … Meer weergeven Some important classes of olefin metathesis include: • Cross metathesis (CM) • Ring-opening metathesis (ROM) Meer weergeven "Olefin metathesis is a child of industry and, as with many catalytic processes, it was discovered by accident."
