METAL HYDRIDE COMPLEX, METHOD OF HYDROGENATING RING-OPENING POLYMERIZATION POLYMER OF CYCLOOLEFIN, AND PROCESS FOR PRODUCING PRODUCT OF HYDROGENATION OF RING-OPENING POLYMERIZATION POLYMER OF CYCLOOLEFIN

摘要

A metal hydride complex which is a hydride complex of a metal selected from the group consisting of ruthenium, rhodium, osmium, and iridium and has one or more aromatic carboxylic acid residues. It is a novel metal hydride complex which dissolves in a high concentration in organic solvents having low polarity, such as hydrocarbon solvents, and which has high catalytic activity in the hydrogenation of carbon-carbon double bonds. The metal hydride complex is suitable for use as a catalyst especially in the hydrogenation of a ring-opening polymerization polymer of a cycloolefin.
