Abstract
The H-1, C-13 and F-19 nmr spectra of etrafluoro-5,6-dihydrobenzo[b]na phth[2,1-f]oxyepin (1) were totally assigned using a combination of tw o-dimensional nmr techniques. Unequivocal interpretation of the spectr al data allowed the complete assignments of the resonances. In additio n, the spectra of compound 1 revealed an unusual through-space carbon- fluorine coupling which was further supported by NOE and modeling expe riments.
