Abstract
Lanthanide-induced shifts
are discussed for 38 naphthoquinones incorporating a wide variety of substituents.
For substrates unsymmetrically substituted in the
benzenoid ring the shift reagent leads to spectroscopic differentiation of the quinonoid protons H2 and H3 in most cases. This has
permitted assignment of substituents to one or other of these positions, an
approach exemplified forderivatives of 5- and
6(7)-methoxy-1,4-naphthoquinone.
