Opis:: Some novel substituted hydrazone derivatives of amino guanidine have been synthesized with different substituted benzaldehydes by condensation method. The synthesized hydrazones were characterized by their physical constants, UV, IR and NMR spectra. The spectral data have been correlated with Hammett substituent constants and Swain–Lupton parameters. From the result of statistical analysis, the effects of substituents on the spectral data have been predicted. The antimicrobial activities of these synthesized hydrazone compounds have been screened by Bauer-Kirby method using human pathogenic bacteria and fungal species. The antimicrobial activities of all synthesized hydrazone compounds have shown significant activity.

Opis:: A series of substituted (E)-N-benzylidene-5-bromopyridin-2-amine compounds have been synthesized from 5-bromo-2-aminopyridine with different substituted benzaldehydes. The structure of the adducts was confirmed by their physical constants, UV, IR and NMR spectral data. The observed UV absorption maximum λmaxC=N(nm), IR frequencies νC=N(cm-1), The 1H and 13C NMR δ(ppm) chemical shifts values 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 spectral data has been studied. The antimicrobial activities of all synthesized imines have been studied using Bauer-Kirby method.

Opis:: A series of N-(substituted phenyl) formamides were synthesised by sulphated titania (TiO2-SO4 2-) catalyzed formylation of substituted anilines and formic acid in acetonitrile medium at room temperature. The synthesised formamide derivatives are characterized by their spectral data. The infrared νNH, CO (cm-1) stretches, chemical shifts(δ, ppm) of NH, COH and ipso carbons(Ar-C-NH) were assigned and correlated with Hammett substituent constants using single and multi-regression analysis. From the results of statistical analyses, the effect of substituents on the spectral data have been studied.

Tytuł:: Synthesis, spectral studies and insect antifeedant activities of some 4-substituted 1-naphthacyl bromide and its esters
Autorzy:: Thirunarayanan, Ganesamoorthy
Powiązania:: https://bibliotekanauki.pl/articles/763926.pdf

Opis:: About nine 4-substituted 1-naphthacyl bromides and its esters have been synthesized by greener synthetic method using fly-ash catalyzed water mediated reaction. These acyl bromides and esters have been characterized by their physical constants, Mass, IR and NMR spectral data. These carbonyl frequencies(cm-1) of existed rotomers of these compounds have been assigned and correlated with Hammett substituent constants, F, R and Swain-Lupton’s parameters. The insect antifeedant activities of the synthesized acyl bromide and esters have been evaluated using 4th instar larvae Achoea Janatha L.
