RUTHENIUM COMPLEX, METHOD FOR PRODUCING THE COMPLEX, POLYMERIZATION CATALYST AND METHOD FOR PRODUCING CYCLIC OLEFIN POLYMER

摘要

PROBLEM TO BE SOLVED: To obtain a new ruthenium carbene complex by a simple preparation method, useful as a catalyst for a metathesis polymerization for a cyclic olefin. SOLUTION: This new ruthenium carbene complex contains three imidazole carbenes and two chlorine atoms as ligands. The ruthenium carbene complex is useful as a polymerization catalyst for a cyclic olefin.
