Four-bond interproton spin-spin coupling in pyridines

Mostrar todas las versiones(2)

The INDOR technique has been applied to determine the sign of the coupling constant between protons in the ring position a in 4-aminopyridine and 4-chloropyridine which, contrary to the usual assumptions, were found to be positive, a result in agreement with the trend in other heterocyclic compounds...
