Schiff bases of aromatic amines and β-diketones including those containing Ph end-groups have been shown to exist as the keto-amine tautomer using NMR spectroscopy. The Schiff bases derived from aromatic amines and 2-hydroxyl-1-naphthaldehyde were concluded to be an equilibrium mixture of the ketoenamine and enolimine forms. The influence of electronic effects in the aromatic amines on the hydrogen-bond
使用NMR光谱法已显示芳香胺和β-二酮的席夫碱(包括含Ph端基的席夫碱)作为酮胺互变异构体存在。衍生自芳族胺和2-羟基-1-萘醛的席夫碱被认为是酮烯胺和烯醇胺形式的平衡混合物。还研究了芳族胺中电子效应对氢键强度的影响。
