The invention relates to new (pre)catalysts of ruthenium complexes of formula (I), wherein L1, X, X', R1, R2, R3 and n are defined herein. The novel ruthenium complexes of formula 1 are convenient (pre)catalysts for metathesis reactions and can be applied i.e. for ring-closing metathesis, cross metathesis or ene-ine metathesis reactions. Another aspect of the invention are the novel intermediates of formula (II).

L'invention concerne des nouveaux (pré)catalyseurs de complexes de ruthénium représentés par la formule (I) dans laquelle L?1¿, X, X', R?1¿, R?2¿, R?3¿ et n ont la définition qui leur est attribuée dans le descriptif. Les nouveaux complexes de ruthénium de formule (I) constituent des (pré)catalyseurs pratiques pour des réactions de métathèse, notamment pour des réactions de métathèse de fermeture de noyau, de métathèse croisée ou de métathèse ène-ine. Un autre aspect de l'invention concerne des nouveaux intermédiaires représentés par la formule (II).
