The Stability

Binary and ternary complexes of the type M-Y and M-X-Y [M = Mn(II), Ni(II), Cu(II) and Zn(II); X = 5-bromosalicylidene-4-methoxyaniline and Y = salicylidene-2,3-dimethylaniline] have been examined pH-metrically at 27±0.5°C and at constant ionic strength, μ = 0.1 M (KCl) in 75 : 25(v/v) 1,4-dioxne-water medium. The stability constants for binary (M-Y) and ternary (M-X-Y) systems were calculated.

The Stability

Methods of preparing 2,3-dioximes of various substituted acetoacetamides are presented. The dissociation constants of these compounds and the stability constants of their metal chelates were determined by potentiometric pH measurements. The influence of the substituents of the amide group on the change of stability is discussed.

The Stability

The preparation of 3-monoximes of different substituted acetoacetamides is described. The dissociation constants of these compounds and also the stability constants of their metal chelates were determined by potentiometric pH-measurements. The change of stability constants by the substituents of the amide group is interpreted.
