通过对23个羟基蒽醌衍生物的质子核磁共振研究,观察了不同取代类型羟基的化学位移范围;讨论了酚羟基乙酰化对芳环质子的化学位移影响,为羟基取代位置的确定及芳环质子谱线归属提供了某种判据.此外,还用 HMO 法探讨了各类取代羟基的氢键强度及羰基迫位仅有一个羟基的内氢键强度与给予原子电荷密度的关系.
The chemical shift range of different substituted hydroxyl groups was observed by proton nuclear magnetic resonance of 23 hydroxyanthraquinone derivatives. The influence of phenylacetylhydroxylation on the chemical shift of aromatic protons was discussed, and the position of hydroxyl substitution and aromatic ring Proton spectrum attribution to provide some criteria.In addition, HMO method is also used to explore the various types of substituted hydroxyl hydrogen bond strength and the carbonyl position only one hydroxyl hydrogen bond strength and atomic charge density relationship.
