1′-Phthalazine hydrazone of diacetyl monooxime and its complexes with transition metals: Physicochemical and theoretical study
摘要:
1'-Phthalazine hydrazone of diacetyl monooxime and its Cu(II) and Ni(II) complexes were synthesized. The acid-base properties of the hydrazone were potentiometrically and spectrophotometrically studied, and quantum-chemical calculations of the ionization constants and the energies of possible tautomeric forms and conformations were performed. Complexes of copper(II) prepared by the reaction of the hydrazone with copper(II) acetate, chloride, and bromide were shown to have the dimeric structure with the bidentatebridging N-O-groups of the oxime fragment, whereas the copper(II) complex prepared from copper(II) nitrate, forms the dimer via the endocyclic nitrogen atoms of the phthalazine fragment.

Structure, tautomeric rearrangements, acid-base properties and complex formation ability of 1-hydrazinophthalazine hydrazones and their coordination compounds with transition metals are considered. The main factors influencing the structure and physicochemical properties of the complexes, biological activity of phthalazine hydrazones and their complexes are discussed.
