Notes:
The magnitude of the 4J proton-proton coupling constant across the fragment CH3—C—C—H (a probe of the bond order between the central sp2-sp2 hybridized carbon atoms) has been found to be essentially independent of substitution on a toluene fragment and on the size of the ring containing the ortho-allylic fragment. The coupling constant is sensitive to direct substitution on the ortho-allylic fragment, especially where the substituent is placed α to the methyl group.
