ABSTRACT:
A hydrogenation promoter of the present invention is produced by reacting an alkyne compound or an alkene compound, a palladium compound represented by a general formula Pd(II)XjLk(where L represents a monodentate ligand or a polydendate ligand other than a phosphorus-containing ligand (when two or more Ls are present in the compound, the Ls may be the same or different), X represents an anionic group, j represents a value determined according to the valence of X so that Xjhas a valence of −2 as a whole, and k represents an integer in the range of 0 to 4), and a base in an organic solvent. Specifically, The hydrogenation promoter of the invention includes palladium nanoparticles containing the alkyne compound or the alkene compound as an agglomeration-preventing agent.
