PROCESS FOR THE PREPARATION BY HYDROGENATION OF CATALYSTS BASED ON A TRANSITION METAL AND PHOSPHINE

摘要

The present invention relates to a process for the preparation through hydrogenation of compounds which can be used as catalysts. The disclosed compounds comprise more specifically at least one transition metal with an oxydation degree of 0 or 1 associated to at least one monodentate or bidentate hydrosoluble phosphine. The process for the synthesis of catalysts comprises the hydrogenation of an aqueous solution containing at least one compound of a transition metal and a monodentate or bidentate hydrosoluble phosphine.
