羟基吡啶酮衍生物结构特征的研究
Investigation of structural characteristics of hydroxy-pyridone derivatives
【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.
