NOVEL E-Z EQUILIBRIUM OF N-ALKYL-α-ALKOXYCARBONYLNITRONE IN SOLUTION

Article abstract of DOI:10.1246/cl.1980.1407

Four N-alkyl-α-alkoxycarbonylnitrone were prepared and their NMR specra in C6D6, CDCl3, or CD3SOCD3 were measured.From the analyses of the spectra, it was found that the nitrones exhibited a facile equilibrium in all solvents used and E/Z ratio in equilibrium depended largely on the polarity of the solvent.
