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 of the invention 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. According to the invention, there is provided a new metal hydride complex which is dissolved in an organic solvent having a low polarity such as a hydrocarbon solvent at a high concentration and has a high catalytic activity of hydrogenating carbon-carbon double bonds. The metal hydride complex relating to the invention is especially suitable as a catalyst in the hydrogenation reaction of a cycloolefin ring-opening polymer.
