“…Schiff's bases, derived from aromatic amines and aromatic aldehydes are reported to be involved in the study of asymmetric catalysis 3 , agnetic properties 4 , photochromism 5 , binding with DNA 6 , construction of supra molecular structures 7 , the study of activity against Ehrlichascites carcinoma (EAC) 8 the field of dyes and pigments 9 , the development of corrosion inhibitors 10 , anti-HIV 11 and in the evaluation of physical properties in the crystalline state 12 . Optically active imine derivatives possess multipronged biological activities such as antimicrobial 13 , anticancer 14 anti-tubularcular [15][16][17] , nematicidal-insecticidal 18 , anti-inflammatory and lipoxygenas 19 . The imine moieties are important intermediates and versatile starting materials for the synthesis of chiral amines 20 , pyrimidine derivatives 21 33,35 .…”
A series of aryl imines have been synthesized by SiO 2 -H 3 PO 4 catalyzed microwave assisted condensation of amine and aldehyde under solvent-free conditions. The yield of the imines has been found to be more than 80%. The purity of all imines has been checked using their physical constants and spectral data as published earlier in literature. The UV λ max (nm), infrared νC=N(cm -1 ), NMR δ(ppm) of C-H and C=N spectral data have been correlated with Hammett substituent constants and F and R parameters using single and multi-linear regression analysis. From the results of statistical analysis, the effect of substituents on the above spectral data has been studied. The antimicrobial activities of all imines have been studied using Bauer-Kirby method.

Conclusion
“…The imine starting materials and important intermediates were used for the synthesis of pharmacologically active heterocycles including triazoles, trizolones [20][21][22]. Optically active imine derivatives possess biological activities such as antimicrobial [23], anticancer [24], antiplasmodic-antihypoxic [25], antitubularcular [26], nematicidal insecticidal [17], anti-inflammatory and lipoxygenase [27]. Hence the authors have taken efforts to synthesis of some imines by perchloric acid catalyzed condensation of aryl amines with various substituted benzaldehydes.…”
A series of Schiff's bases (aryl E-imines) have been derived from the perchloric acid catalyzed condensation of aryl amines and substituted benzaldehydes. The yield of the Schiff's bases are more than 80%. The synthesized Schiff's bases are characterized by their physical constants, analytical and spectroscopical data. The antibacterial activities of these Schiff's bases have been studied using Bauer-Kirby method.
