  1. Olefin metathesis - Wikipedia

    • Olefin metathesis Reaction type Carbon-carbon bond forming reaction Identifiers Organic Chemistry Portal olefin-metathesis RSC ontology ID RXNO:0000280 Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes 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 alternative organic reactions. For their elucidation of the

  7. Alkyne metathesis - Wikipedia

    • Alkyne metathesis is an organic reaction involving the redistribution of alkyne chemical bonds. This reaction is closely related to olefin metathesis. Metal-catalyzed alkyne metathesis was first described in 1968 by Bailey, et al. The Bailey system utilized a mixture of tungsten and silicon oxides at temperatures as high as 450 °C. In 1974 Mortreux reported the use of a homogeneous catalyst—molybdenum hexacarbonyl at 160 °C—to observe an alkyne scrambling phenomenon, in which an...
