Long range 13C-1H-coupling constants at bridgehead carbons in some naphthalene and quinoline derivatives, “cross” ring and “through” ring interactions
The 3JCH couplings at bridgehead carbons in naphthalene and quinoline derivatives have been classified as “through” ring and “cross” ring interactions.Further divisions of the couplings have been introduced in an attempt to rationalize the interactions such that they may be used for structural assignments.The influence of central ?-bond order and of the heterocyclic nitrogen atom on the couplings has been discussed.From a study of the 3J couplings at C-9 and C-10 in 45 quinoline derivatives the coupling constant ranges observed were “through” ring (via 9,10-bond): J94 4.9-6.1 Hz, J95 5.5-7.3 Hz, J10.8 4.1-5.3 Hz; “cross” ring: J92 11.0-13.5 Hz, J97 6.7-9.8 Hz, J10.3 4.4-7.3 Hz, J10.6 5.2-9.1 Hz.
