The present invention relates to an electrochemical process for the preparation of compounds which can be used as catalysts. The disclosed compounds comprise more specifically a transition metal with an oxidation degree of 0 or 1 associated to at least one monodentate or bidentate hydrosoluble phosphine. The process for the electrochemical synthesis of catalysts comprises the treatment by electrolysis of an aqueous solution containing at least a compound of a transition metal and a monodentate or bidentate hydrosoluble phosphine placed within the cathode compartment of an electrolysis cell of an electrolyser.
