N,N'-ethylene-bis(benzoylacetoniminato) copper (II), Cu(C22H22N2O2), a new reagent for aromatization of Hantzsch 1,4-dihydropyridines.
A variety of Hantzsch 1,4-dihydropyridines were oxidized to their corresponding pyridines in high yields in the presence of Cu(C22H22N2O2) in refluxing acetic acid.
