The hydrogenation reaction can be carried out at a very high speed with a small amount. The hydrogenation accelerator of the present invention comprises an alkyne compound or an alkene compound in an organic solvent and a general formula Pd (II) X j L k (wherein L is a monodentate or excluding a phosphorus-containing ligand) A polydentate ligand (when two or more L are present in the compound, they may be the same or different from each other independently), X is an anionic group, j is X j is This is obtained by reacting a palladium compound comprising a value determined according to the valence of X so as to be divalent, k being an integer of 0 to 4) and a base. .
