Reactions of cobalt resacetophenone oximate with heterocyclic nitrogen bases

Summary Adduct formation constants of the pyridine adducts of the cobalt(II) chelate of resacetophenone oxime in cyclohexanone have been determined spectrophotometrically. Spectral changes in the absorbance were observed in visible range. The stability of the cobalt adducts increases in the following order of the bases: pyridine<4-picoline<3,5-lutidine<1,10-phenanthroline<2,9-neocuproin<2,2-bipyridyl.
