Novel mono- and dimolybdenum-dinitrogen complexes bearing an arsenic-containing ANA-type pincer ligand are prepared and characterized by X-ray analyses. These complexes afford a stoichiometric amount of ammonia by treatment with sulfuric acid at room temperature.
Dinuclear and mononuclear rutheniumcomplexesbearing an arsenic-containing arsenic-nitrogen-arsenic (ANA)-type pincerligand are designed, prepared, and characterized by X-ray analyses. Both rutheniumcomplexes work as effective catalysts toward dehydrogenative transformations of alcohols.
