Outline of Final Research Achievements

Based on the previous findings we have achieved so far, we have investigated two research topics. One is the development of ammonia synthesis under mild reaction conditions. The other is the development of decomposition of ammonia under mild reaction conditions.
As to the former research topic, we have designed and prepared new dinitrogen-bridged dimolybdenum complexes bearing triphosphine and PCP-type pincer ligand. In addition, these newly prepared molybdenum-dinitrogen complexes have been found to work as effective catalysts than the original complex bearing PNP-type pincer ligand.
As to the latter case, we have designed and prepared initrogen-bridged dimolybdenum complexes bearing ferrocenyldiphosphine and we have disclosed a unique reactivity, where cleavage and recombination of the nitrogen-nitrogen triple bond of the bridged dinitrogen on the two molybdenum atoms have been reversibly controlled by the redox of the molybdenum centers.
