, p. 261 - 267 (2005)
Optimal conditions were found for the reactions of aniline and its hydroxy-, carboxy-, methyl-, and nitro-substituted derivatives with p-dimethylaminocinnamaldehyde in the presence of sodium dodecyl sulfate micelles in the pH range 1-6. A correlation was revealed between the optimal pH value pK a of aromatic amines. The reaction in the model system aniline-p-dimethylaminocinnamaldehyde-sodium dodecyl sulfate in micelles formed by anionic surfactants is accelerated more than 1000-fold due to increased concentration of the reactive species in sodium dodecyl sulfate micelles. 2005 Pleiades Publishing, Inc.

The successive formation constants of copper(II) and proton complexes of the Schiff base, 2-(4-dimethylaminocinnamalamino)phenol (DACAP) formed by condensation reaction of 4-dimethylamianocinnamaldehyde and 2-aminophenol were determined in the aqueous solutions of acetone and dioxane at 25 ± 0.1°C and an ionic strength of 0.1 M by potentiometric pH measurements. Calculations were performed with the weighted least square method by means of the PKAS and BEST computer programs. The distribution diagram of the complex species was drawn as a function of the pH. The solvent effect on different protonation sites of the ligand was discussed. Some characteristic specifications of the ligand and the copper(II) complex were also described. Together with the formation of [CuL]+ and CuL2, complexes, the presence of CuL(OH)n(n-1)- hydroxo complexes were also observed at rather basic region and their corresponding formation constants were determined.
