“…Some of the single parameter correlations of carbonyl group frequencies with Hammett substituent constants, F and R parameters were found to be poor. Therefore the author has decided to investigate the multi-regression [60][61][62][63][64][65] analysis of these carbonyl group frequencies with Swain-Lupton's [56] parameters, inductive and resonance effects of the substituents. The obtained multi-regression equations are presented in Table 3.…”

“…These chemical shifts are correlated separately with various Hammett substituent constants. The results of statistical analysis [59][60][61][62][63][64][65] of these chemical shifts are presented in Table 2. The Hammett σ R constants show only a fair degree of correlation with the chemical shifts (ppm) of carbonyl carbon of 4-substituted 1-naphthacyl bromides.…”

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.
