✦ Synopsis


The proton-coupled 13C NMR spectra of 2-, 3-and 4-fluoropyridines were completely analysed and the signs and magnitudes of the 13C-1H coupling constants determined. The root mean square deviations of the observed J(CH) values from those calculated using empirical correlations between the coupling constants in monosubstituted pyridines and benzenes were found to be 0.90 Hz for 'J(CH) and less than 0.26 Hz for the other "J(CH) couplings.
