Four N-alkyl-α-alkoxycarbonylnitrones were prepared and their NMR spectra 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.
制备了四种N-烷基-α-烷氧基羰基硝酮,并测量了其在C6D6、CDCl3或CD3SOCD3中的核磁共振光谱。通过光谱分析发现,硝酮在所有溶剂中均表现出易平衡性,平衡中的E/Z比值主要取决于溶剂的极性。
