摘要
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 DEFT 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.
