Av. Afonin et al., Simple procedure for determination of configuration of ketone oximes and their derivatives by C-13 NMR spectroscopy, RUSS J ORG, 36(12), 2000, pp. 1777-1783
Differences in the chemical shifts of the alpha -carbon atoms in (E)- and (
Z)-ketone oximes can be used as a universal criterion for determination of
their steric configuration.
