Equilibrium constants and center of formation of H-complexes of hydrazones with p-nitrophenol

Conclusions The center of formation of H-complexes of hydrazones with p-nitrophenol is the imine nitrogen atom. This direction of interaction is determined by the potential of the electrostatic field. Experimental values of the complex formation constants vary in proportion to the calculated values of the charge on the imine nitrogen atom.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2493–2497, November, 1981.The authors wish to thank T. N. Pylaeva and L. V. Ermolaeva for assistance in synthesis of the hydrazones and for their discussion of the results.
