Long range coupling constants and 13C chemical shifts are given for the compounds of the title. Evidence of interring coupling is presented. 1 \_ introduction The 13C--H spin-spin coupling constants are of great interest in theoretical studies and in the assignment of the 13C resonance [l] \_ Numero
The long-range 'H-l'F coupling reported earlier for the bridgehead proton(s) in 1,4dihydro-1,4\_epoxynaphthalenes (e.g., 1) is shown unequivocally to involve the distal fluorine by a five-bond zig-zag coupl%g pathway.
