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 H 2 and H 3 in most cases. This has permitted assignment of substituents to one or other of these positions, an approach exemplified for derivatives of 5- and 6(7)-methoxy-l, 4-naphthoquinone.
