Outline of Final Research Achievements

Novel dimolybdenum- and diruthenium-dinitrogen complexes bearing an
arsenic-containing ANA-type pincer ligand are desinged, prepared and characterized. The former complex affords a stoichiometric amount
of ammonia by treatment with sulfuric acid at room temperature, while the latter complex works as and effective catalyst toward dehydrogenative transformations of alcohols. Catalytic formation of ammonia from dinitrogen using water as a proton source has been also achived by using dimolybdenum-dinitrogen complex bearing a PNP-type pincer ligand as a catalyst.
