T. Parella et al., REGIOSELECTIVITY STUDIES BY SELECTIVE DETECTION OF LONG-RANGE HETERONUCLEAR COUPLINGS FROM THE SDEPT-1D METHOD, Magnetic resonance in chemistry, 32(6), 1994, pp. 343-347
Some regiosomers formed by palladium(0)-catalysed allylation of severa
l ambident heterocyclic nucleophiles, among others, were easily distin
guished in very short spectrometer times by selective polarization tra
nsfer via DEFT from well resolved protons to long-range coupled carbon
s using the SDEPT-1D experiment. This pulse sequence was also analysed
in terms of the product operator formalism. These structural elucidat
ions can provide useful information about the regioselectivity in thes
e reactions.
