Correlation analysis of IR, H-1 NMR and UV spectral data of alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones. Part I
(Arkat Usa Inc, Gainesville, 2006)
Spectral characteristics of the two series of previously synthesized and identified 4,6-disubstituted- 3-cyano-2-pyridones were determined, and corresponding H-1 NMR chemical shifts and IR and UV frequencies were correlated ...
Correlation analysis of IR, 1 H NMR and UV spectral data of alkyl and aryl 4,6-disubstituted-3-cyano-2-pyridones. Part I
(Arkivoc, 2006)
Spectral characteristics of the two series of previously synthesized and identified 4,6-disubstituted-3-cyano-2-pyridones were determined, and corresponding 1 H NMR chemical shifts and IR and UV frequencies were correlated ...
Solvent and substituent effect on electronic spectra of N-(4-substitutedphenyl)-2,3-diphenylpropanamides
(Arkat Usa Inc, Gainesville, 2006)
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects ...
