Taya, Toshiki published the artcileComplexation behavior of heterocyclic hydrazones. I. Structure and acid-base equilibria for heterocyclic hydrazones, Application In Synthesis of 2215-33-0, the publication is Bulletin of the Chemical Society of Japan (1993), 66(12), 3652-61, database is CAplus.

The acid-base equilibrium of twenty-one hydrazones substituted by Ph, pyridyl and/or quinolyl groups have been investigated in aqueous solutions over the region of H– to H0 acidity function by a spectrophotometric method at 25 °C. For 2-pyridinecarbaldehyde 2-(5-substituted)pyridylhydrazones, although the proton dissociation of the neutral species (HL) satisfied a Hammett correlation, those of H2L+ and H3L2+ did not. The thermodn. parameters for the proton dissociations of H2L+ of seven representative ligands were determined by a temperature-coefficient method at 25 °C and an ionic strength of 0.1 (KCl). The enthalpy and entropy changes for the proton dissociations of H3L2+ and H2L+ were influenced by the steric effects of the Me group and/or the introduced quinolyl ring. An anal. of the pH dependence of the 1H NMR signals for three hydrazones in an acetone-d6-D2O solution gave more profitable information concerning the fine structures of HL, H2L+, and H3L2+. Each 1H and 13C NMR chem. shift of some ring-substituted Me derivatives (HL form) in a dioxane-D2O solution has been briefly assigned. On the other hand, a single-crystal X-ray anal., 1H NMR data in chloroform-d and thermodn. data for di-2-pyridyl ketone 2-pyridylhydrazone (DPPH) suggested that the intramol. hydrogen bond in the DPPH mol. is broken by the addition of a proton on the H2L+ species in an aqueous solution
