Hydrogenation with Anthranilic Acid Anchored, Polymer-Bound Nickel Catalysts

Article abstract of DOI:10.1021/jo01296a015

A Ni^II polymer-bound catalyst was prepared by anchoring anthranilic acid to chloromethylated, highly crosslinked polystyrene beads and then equilibrating with NiCl2*6H2O.By treating this catalyst with sodium borohydride, a second catalyst was prepared.Both nickel catalysts are active in the hydrogenation of alkenes and dienes and in the reduction of nitrobenzene.The structures of the catalysts were probed by XPS studies.
