Summary:The subject matter of the invention is a stereoretentive ruthenium complex of the general formula 1a-Ru and/or 1b-Ru, in which all variables have the meanings defined in the description. The subject matter of the invention is also a method of preparing the ruthenium complex, an intermediate used in preparing the ruthenium complex, and the use of this ruthenium complex as a (pre)catalyst in olefin metathesis reactions such as ring-closing metathesis (RCM), homometathesis (self-CM), cross-metathesis (CM), and stereoretentive processes in olefin metathesis. L'objet de l'invention concerne un complexe de ruthénium stéréorétentif de formule générale 1a-Ru et/ou 1b-Ru, dans laquelle toutes les variables ont la signification indiquée dans la description. L'objet de l'invention concerne également un procédé de préparation du complexe de ruthénium, un intermédiaire utilisé dans la préparation du complexe de ruthénium, et l'utilisation de ce complexe de ruthénium en tant que (pré)catalyseur dans des réactions de métathèse d'oléfines telles que la métathèse à fermeture de cycle (RCM), l'homométathèse (auto-CM), la métathèse croisée (CM), et des processus stéréorétentifs dans la métathèse d'oléfines.
