A ruthenium-based metathesis catalyst system which contains a ruthenium compound (A), a phosphorus compound (B), and a compound (C) containing a carbon-to-carbon triple bond. The mole ratio of compounds A:B:C is typically in the range of about 1.0:0.01- 100:0.01-100. The ruthenium compound (A) is a Ru(II), Ru(III), or Ru(IV) compound containing an anionic ligand (X) and optionally an arene ligand and optionally a phosphorus compound ligand. The phosphorus compound (B) is optional if the ruthenium compound (A) contains a phosphorus-containing ligand.
L'invention concerne un système de catalyseur pour la métathèse, qui contient un composé de ruthénium (A), un composé phosphoré (B) et un composé (C) contenant une triple liaison carbone-carbone. Le rapport molaire entre les composés A: B: C est généralement d'environ 1,0: 0,001-100 : 0,01-100. Le composé de ruthénium (A) est un composé Ru(II), Ru(III) ou Ru(IV) contenant un ligand anionique (X), éventuellement un ligand arène et éventuellement un ligand qui est un composé phosphoré. Le composé phosphoré (B) est facultatif quand le composé A du ruthénium contient un ligand qui est un composé phosphoré.
