Ethyl 1,4-dihydro-1-ethyl-4-oxoquinoline-3-carboxylate and 29 of its mono-, di-and tri-fluoro and/or -chloro derivatives were synthesized and their 1H, 13C and 19F NMR spectra were recorded. 1H, 13C and 19F chemical shifts, JHH, JFH, JCF and JFF coupling constants are reported. The 13C substituent chemical shift values of the chloro and fluoro substituents were calculated by linear multiple regression.
