摘要：

In the H-1-NMR spectra of model compounds 1-3 in hexadeuteriobenzene the signals of protons at the E-side of the nitrone group are more extensively shifted to higher field by the effect of the aromatic solvent than the signals of protons at the Z-side. Utilizing this effect the existence of usual C,N-dialkylnitrones in the Z-form was confirmed. C-Acylnitrones as 8 and 9, however, exist in both of the isomeric forms, the equilibrium being strongly influenced by the solvent.
