Notes:
1H and 13C NMR spectra of 8-hydroxyquinoline (oxine) and its 5-Me, 5-F, 5-Cl, 5-Br and 5-NO2 derivatives have been studied in DMSO-d6 solution. The 1H and 13C chemical shifts and proton-proton, proton-fluorine, carbon-proton and carbon-fluorine coupling constants have been determined. The 1H and 13C chemical shifts have been correlated with the charge densities on the hydrogen and carbon atoms calculated by the CNDO/2 method. The correlation of the 1H and 13C chemical shifts with the total charge densities on the carbon atoms is approximately linear (rH2 = 0.85, rC2 = 0.84). The proton in peri position to the nitro group in 5-NO2-oxine is an exception.
