The 1H chemical shifts, 1H-1H coupling constants, 13C chemical shifts, and some 1H-13C and 13C-19F coupling constants have been determined for seven 3-substituted-9-chloroacridines and for the corresponding 3-substituted-9-aminoacridines. The effects

Thirty-four benzoxazoles, oxazole, and 10 o-aminophenols have been studied by 13C nmr spectroscopy. All the signals have been attributed from substituent effects. The structure of products obtained by nitration of benzoxazole have been determined by

During a general n.m.r. study of five-membered heterocycles with two hetero-atoms, we measured the 13C chemical shifts, the vicinal couplings [Formula: see text] and the long range couplings for a series of variously substituted isothiazoles. At that

Carbon-13 nmr spectra of 18 thiazoles with different substituents (R = CH3, C6H5, Cl, Br, NH2 et N3) have been recorded. The 13C chemical shifts and the nJ(C,H) coupling constants are discussed as a function of the nature of the substituent and the e
