Abstract

Eight different substituted Schiff bases are prepared by the reaction of 2-amino-4,7-dimethyl benzothiazole with eight different substituted aldehydes. All the synthesized Schiff bases were analysed by spectral analysis such as IR, 1H NMR, Mass and by elemental analysis. The Schiff bases were screened for antibacterial activity against four bacterial strains such as E. coli, S. typhi, S. aureus, B. subtilis and fungicidal activity against A. niger, A. flavus, P. chrysogenum and F. Moneliforme

Abstract

In the present paper an attempt was made to study dicarboxylate of Cu (II) and Mn (II) metals with heterocyclic Nitrogen bases as adducts in principle for their structure and properties. Salts of Cu++ and Mn++and dicarboxylic acids such as oxalic, succinic, Glutaric, Adipic acids were taken in 1:1 proportion and refluxed in heterocyclic bases such as pyridine, Quinoline, &#946;-picoline or Nicotine. After filtration and cooling transition metal carboxylates with adducts of bases of Nitrogen and Nicotine were obtained. All the compounds were analysed by elemental analysis, solubility, magnetic susceptibility, IR, <SUP>1</SUP>HNMR spectra and thermal analysis. All the synthesized compounds are paramagnetic. IR spectra showed that bonding of dicarboxylic acid to transition metal ion is through oxygen and of heterocyclic base and Nicotine is through Nitrogen.

Abstract

A series of 1, 3-diaryl-2-propene-1-ones have been synthesized by using conventional Claisen-Schmidt condensation method in alkaline methanolic solution. The structures of the products were confirmed by spectral analysis (IR, ¹H NMR and Mass). All the newly synthesized compounds were screened for their antibacterial and antifungal activity.
