Abstract
The proton-decoupled 13C spectrum of 2-fluoronaphthalene has been reassigned and reveals a six-bond coupling of 2·8 Hz between the fluorine and C-6; a similar coupling is observed in 4-fluorostyrene; long-range 13C–19F coupling constants in other fluorinated aromatics appear to be related to variations in the π-bond orders in the bonds between the interacting spins.Keywords
