According to the present invention there is provided a compound in the form of a transition metal compound including a transition metal, a phosphorus containing ligand, and a cyclic organic ligand. The phosphorus containing ligand is a heterocyclic organic compound with a ligating phosphorus atom which ligates with the transition metal, and which ligating phosphorus atom is an atom in the heterocyclic ring structure of the heterocyclic organic compound. The cyclic organic ligand is a cyclic organic compound with a ligating carbon atom in the cyclic ring structure of the cyclic organic compound which ligates with the transition metal by means of a double bound. The invention also relates to a method preparing such a compound and a metathesis reaction wherein such a compound is used as a catalyst.
La présente invention se rapporte à un composé, qui se présente sous la forme d'un composé à métal de transition renfermant un métal de transition, un ligand contenant du phosphore et un ligand organique cyclique. Le ligand contenant du phosphore est un composé organique hétérocyclique doté d'un atome de phosphore de ligature qui se ligature avec le métal de transition, ledit atome de phosphore de ligature étant un atome contenu dans la structure hétérocyclique du composé organique hétérocyclique. Le ligand organique cyclique est un composé organique cyclique doté d'un atome de carbone contenu dans la structure cyclique du composé organique cyclique, ledit atome de carbone se ligaturant avec le métal de transition à l'aide d'une double liaison. L'invention a également trait à un procédé permettant de préparer un tel composé, et à une réaction de métathèse utilisant un composé en tant que catalyseur.
