    Abstract: There is disclosed a number of processes for the promotion of the Raney Nickel catalyzed hydrogenation of carbon-carbon double bonds. (a) One process uses tertiary amines to promote the Raney Nickel catalyzed hydrogenation. (b) Another process uses acetylene and acetylene derivatives to promote the Raney Nickel catalyzed hydrogenation. The promotion of Raney Nickel catalyst is particularly suited for the reduction of unsaturated hydantoins to saturated hydantoins and also for the reduction of cyclic and acyclic olefins and diolefins to the corresponding cyclic and acyclic alkanes.
