摘要：
High resolution H-1 NMR spectra of two 1,1'-binaphthols (I, II), two 1,1'-binaphthalenediols (III, IV) and four 1,1'-binaphthalenediol acetates (IIIa - VIa) were obtained and analyzed. The effect of the ring current was evaluated by comparing the chemical shifts of the compounds, assigned through H-H COSY NMR experiments, to those of the corresponding monomers. All experimental chemical shifts arc in close agreement with the theoretical values obtained via the Bovey model for the ring current effect of a benzene moiety.
