getting condensed p-N,N-diethylaminobenzaldehyde with two presented hippuric acid derivatives and in further studies they were analysed spectrochemically. Molecular and crystal structures of the compounds were determined by single-crystal X-ray diffraction and the results revealed that the molecular packing of the crystal structures were stabilized by weak intraand intermolecular interactions also with
在这项研究中,通过将pN,N-二乙基氨基苯甲醛与两个存在的马尿酸衍生物缩合,合成了两个恶唑5-酮衍生物C20H20N2O2(1)和C21H22N2O2(2),并在进一步的研究中对它们进行了光谱化学分析。通过单晶X射线衍射确定了化合物的分子和晶体结构,结果表明,与CO∙∙∙π,CH∙∙∙π和π∙∙∙π堆叠相互作用。还使用DFT方法在B3LYP / 6-311G(d,p)的理论水平上进行了计算研究。计算了振动模式和化学位移,并与实验数据进行了比较。此外,还模拟了前沿分子轨道和分子静电势面。计算结果表明,优化的几何形状可以很好地再现晶体结构。这项研究的目的是调查反应物的反应,这些反应物彼此缩合以生成恶唑-5-酮,对最终恶唑-5-酮的特征和晶型产生影响。
