Antimicrobial activities - Opis:
- Elven (E)-1-(4-bromophenyl)-3-(substituted phenyl)-2-propen-1-ones are formed using sodium hydroxide catalyzed Aldol condensation between 4-bromoacetophenone and substituted benzaldehyde. The production of these chalcone compounds are above 90%. These α, β unsaturated ketones were specified by their physical constants and spectral data (UV, IR, 1H and 13C-NMR). Hammett substituted constants (σ, σ+, σI & σR and F and R parameters have been used for correlating the spectral values of these α, β unsaturated ketones by using single and multi-linear regression analysis. The impacts of substituents on the spectral data have been known on statistical analysis. By using Bauer-Kirby method the anti-microbial activities of these (E)-1-(4-bromophenyl)-3-(substituted phenyl)-2-propen-1-ones compounds are estimated.
