a tautomeric form of a model acireductone, is presented here. Interestingly, the compound was found to crystallise as a stable dimer, a molecule of which contains a 1,3-dioxolane ring. The dimer structure was solved using the PXRD (powder X-ray diffraction) method and confirmed by NMR, IR, and Raman spectroscopy and DFT calculations. The title compound dissolves in water with the formation of several
本文介绍了一种有效的合成途径,可合成1-羟基己烷-2,3-二酮,它是模型acireductone的互变异构形式。有趣的是,发现该化合物结晶为稳定的二聚体,其分子包含1,3-二氧戊环。使用PXRD(粉末X射线衍射)方法解析二聚体结构,并通过NMR,IR,拉曼光谱和DFT计算确认。标题化合物溶于水,形成几种模型的阿昔康酮单体,如紫外-可见和NMR光谱所揭示。还确定了单体的中性和阴离子形式的消光系数。
