A use of the carboxamides aryl carbonyl aminolysis method of preparing amide

The invention discloses a method for preparing amides via a decarbonylation ammonolysis reaction of aryl ester and formamide. The method comprises the following steps: dissolving a palladium catalyst, aryl ester and formamide in a solvent, and stirring fo

Heterogeneous recyclable nano-palladium catalyzed amidation of esters using formamides as amine sources

Catalyzed by supported palladium nanoparticles, a decarbonylative amidation reaction between various aryl esters and formamides by C-O bond activation has been developed for the synthesis of amides. The catalyst can be reused and shows high activity after

Mono- and Binuclear Bis(2,2'-bipyridine)ruthenium Complexes with N,O-Ligands Modelling Dehydrogenase Cofactors

Coordination of substitutionally inert (2+) fragments (bpy: 2,2'-bypiridine) to the α-aminoketone chelate ligands pyrazine-2-dimethylcarboxamide (4) and 4,7-phenanthroline-5,6-dione (5) yields the complexes (2+), (+) and 2>(4+) which exhibit a rich electrochemistry.The distinctly different electronic structures of the complexes are evident from the ESR behaviour of paramagnetic intermediates: N,O-coordinated complexes have the unpaired electron residing in the ligand ? system upon reduction, albeit with g2 for the binuclear complex of 5.The paramagnetic O,O'-coordinated mononuclear complex with 5 has its redox potentials shifted positively relative to that of the binuclear system.These results are particularly noteworthy because 4 and 5 can be regarded as model compounds for the flavin and methoxatin dehydrogenase cofactors. - Keywords: Dehydrogenase Cofactors, Ruthenium Complexes, Oxidation States, ESR Spectra, α-Iminoketones
