N2 - Some regiosomers formed by palladium(0)‐catalysed allylation of several ambident heterocyclic nucleophiles, among others, were easily distinguished in very short spectrometer times by selective polarization transfer via DEPT from well resolved protons to long‐range coupled carbons using the SDEPT‐1D experiment. This pulse sequence was also analysed in terms of the product operator formalism. These structural elucidations can provide useful information about the regioselectivity in these reactions.
