| 摘 要： | 报道了 ７个６－羟基－２－吡啶酮衍生物在溶液中的 １Ｈ－．１３Ｃ－ＮＭＲ波谱和固态的红外光谱数据．实验表明，在常温和酸性介质中井不能使它们以 ６－酮基－２－吡啶酮的结构存在．解释了红外光谱中１８８６—１６３０ ｃｍ－１范围内某些化合物的两条羰基谱带．根据波谱数据，提出了这类化合物在酸性、中性和碱性条件下可能存在的结构形式．

| Abstract: | The 1H, 13C-NMR spectra in the solutions and IR spectra in solid state of seven 6-hydroxy-2-pyridone derivatives are reported. It is demonstrated by experiments that the compounds studied can not exist in the form of 6-keto-2-pyridone at normal temperature and under acidic conditions. The two carbonyl bands in the range of 1 686- 1 630 cm-1 in IR spectra for some samples are explained. The possible structures for these compounds under acidic, neutral and basic conditions are proposed according to the spectral data. |
