Opis:: Schiff bases namely, 2-bromo-4-methyl-N-(2-nitrobenzylidene)aniline; 2-bromo-4-methyl-N-(2,4,5-trimethoxybenzylidene)aniline; 2-bromo-N-(4-methoxybenzylidene)-4-methylaniline and N-((1H-indol-3-yl)methylene-2-bromo-4-methylaniline have been synthesized and characterized by elemental analysis, FT-IR, Mass and 1H-NMR spectroscopy. Schiff bases have been screened for Antimicrobial activity against bacteria and fungi by using MIC determination. Binary complexes of Co(II), Ni(II) and Cu(II) with Schiff bases in solution have been studied potentiometrically in 60:40 % (V/V) 1,4-dioxane-water system at constant temperature 27 ±0.5 ºC and at an ionic strength of 0.1 M KNO3. The order of stability constant of formed binary complexes in solution was examined.

Synthesis
Opis:: A series of Schiff’s base compounds were synthesized from 2,6-di(propan-2-yl) aniline with substituted aromatic aldehydes. The structures of all the synthesized compounds were characterized by physical constants, IR and NMR spectroscopic techniques. All the observed IR frequencies νC=N (cm-1), NMR δ(ppm) of C-H & C=N chemical shifts have been correlated with Hammett substituent constants and F and R parameters using single and multi-linear regression analyses in order to study the effect of substituents on these spectral data has been studied. All the synthesized Schiff’s base compounds were screened for their antimicrobial activity by disc diffusion method.

Opis:: A series of seven titled compounds have been prepared and their purities were examined by literature method. The characteristic infrared stretching frequencies (, cm-1) and the NMR chemical shifts (, ppm) of these anilines were assigned. These assigned spectral data were correlated with Hammett substituent constants, F and R parameters using single and multi-regression analysis. From the statistical results the effect of substituents on the spectral data have been discussed. The antimicrobial activities of these aniline derivatives have been evaluated by Bauer-Kirby disc-diffusion method.
