Outline of Final Research Achievements

Synthesis of polypeptides by alternating copolymerization of imines with carbon monoxide was investigated. The reaction of phenylaldimine with carbon monoxide by mononuclear Pd complex resulted in almost no polymerization. The reaction of cinnamaldimine or cyclobutanimie with carbon monoxide afforded insoluble product or oligomeric product. Dinuclear Pd complexes and aluminum-palladium complexes were designed and utilized for the reaction, but almost no polymerization took place. Aluminum-cobalt and aluminum-nickel complexes were found to show higher catalytic activity toward the polymerization of butadiene than the corresponding mononuclear cobalt and nickel complexes.
