A process for producing organolanthanides by reaction of a rare-earth metal with an unsaturated compound in an ether medium, the resultant compounds and the use of these compounds in organic synthesis and for catalysis is disclosed. The process is conducted at -80.degree. to +100.degree. C., in the absence of oxygen and any compound having active protons. The resultant compounds are useful as catalysts, e.g., in the hydrogenation of olefins and diolefins and in the polymerization thereof, and are useful as chemical intermediates.
