Improved catalysts useful in a number of organic synthesis reactions such as olefin metathesis and atom or group transfer reactions are made by bringing into contact a multi-coordinated metal complex comprising a multidentate Schiff base ligand, and one or more other ligands, with an acid under conditions such that said acid is able to at least partly cleave a bond between the metal and the multidentate Schiff base ligand of said metal complex, optionally through intermediate protonation of said Schiff base ligand.
L'invention concerne des catalyseurs convenant dans un certain nombre de réactions de synthèse organiques telles que la métathèse d'oléfine ou les réactions de transfert d'atomes ou de groupe, que l'on obtient en mettant en contact un complexe métallique multi-coordonné comprenant un ligand mulitcoordinant à base de Schiff et un ou plusieurs autres ligands avec un acide dans des conditions telles que ledit acide puisse cliver une liaison entre le métal et le ligand mulitcoordinant à base de Schiff dudit complexe métallique, éventuellement par protonation intermédiaire dudit ligand à base de Schiff.
