Hydrazones and substituent effect
LFER study
Synthesis
Opis:
A series containing ten substituted hydrazones have been synthesized by condensation between semicarbazide and various substituted benzaldehydes. The hydrazones were confirmed by their physical constants and UV, IR, 1H NMR and 13C NMR spectral data. This UV, IR, 1H NMR and 13C NMR spectral data have been used for LFER studied with Hammett constants and Swain-Lupton’s parameters.

Opis:
A series of substituted of (E)-1-(5-chloro-2-hydroxyphenyl)-3-phenylprop-2-en-1-one compounds by cross-aldol condensation reaction of 5-chloro-2-hydroxy acetophenone with various substituted benzaldehyde in the presence sodium hydroxide (base). The synthesized substituted (E)-1-(5-chloro-2-hydroxyphenyl)-3-phenylprop-2-en-1-one compounds was characterized by physical constants, UV, FT-IR, 1H & 13C-NMR spectral data. All the spectral data of substituted (E)-1-(5-chloro-2-hydroxyphenyl)-3-phenylprop-2-en-1-one compounds has been Hammett correlation with linear regression analyses.

Opis:
A series containing ten substituted (E)-2-benzylidenehydrazinecarbothioamide were synthesized by condensation between thiosemicarbazide and various substituted benzaldehydes. The synthesized (E)-2-benzylidenehydrazinecarbothioamide were characterized by their physical constants and spectral data. The UV C=N λmax (nm), infrared ν C=N (cm-1), 1H NMR δ (CH= N) and 13C δ (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.

Opis:
A series of nine number of (E)-1-benzylidene-2-(4-bromophenyl)hydrazine compounds have been synthesized by the condensation reaction of 4-bromo phenylhydrazine with varies m- and p- substituted benzaldehydes using acetic acid catalyst were refluxed for 4h with 20 mL of absolute ethanol. The yield of synthesized (E)-1-benzylidene-2-(4-bromophenyl)hydrazine compounds are more than 80%. The synthesized (E)-1-benzylidene-2-(4-bromophenyl)hydrazines have been characterized by UV, IR, 1H and 13C spectral data. These UV, IR and NMR spectral data have been correlated with varies Hammett substituted constant and Swain-Lupton F and R parameters using single and multi- regression analysis. From the results of statistical analysis, the effects of substituent have been studied. The antimicrobial activity of all the synthesized substituted (E)-1-benzylidene-2-(4-bromophenyl)hydrazines have been evaluated using Bayer-Kirby method.
