The present invention provides heterogeneous organometallic catalysts for alkyne metathesis, including the metathesis of internal alkynes. Organometallic precursors are covalently bonded to the oxygen atoms of metal oxide supports to form catalysts having carbyne functionality. The heterogeneous catalysts provide improved turn-over frequencies at lower reaction temperatures than conventional catalysts.
L'invention concerne des catalyseurs organométalliques hétérogènes pour une métathèse d'alkyne, y compris la métathèse d'alkynes internes. Des précurseurs organométalliques sont liés par covalence aux atomes d'oxygène de supports d'oxyde métallique afin de former des catalyseurs ayant une fonctionnalité carbyne. Les catalyseurs hétérogènes produisent de meilleures fréquences de renouvellement à des températures de réaction inférieures aux catalyseurs classiques.
