Abstract A number of acetyl-substituted fluoronaphthalenes have been synthesized and their fluorine as well as proton NMR spectra have been measured. The methyl proton resonances of these derivatives appeared as a doublet which indicated long-range coupling with the fluorine. It was observed that the coupling (J Me, F) for 3-acetyl-2-fluoronaphthalene and o- fluoroacetophenone is independent of the magnitude of the 19 F substituent chemical ...
