摘要:
首次开发了一种在微波辐射下合成一系列1-(羟甲基)-吡唑的简便高产率、无溶剂的方法。通过单晶 X 射线衍射对四种吡唑化合物的结构进行了表征,并显示出有趣的分子间 O-H ∙∙∙ N 氢键连接两个吡唑分子形成右22(10)二聚体架构。此外,通过赫什菲尔德表面分析研究了晶体中的分子间相互作用,以了解紧密接触的特征,并且二维指纹图数据揭示了对晶体堆积的显着贡献来自 N ∙∙∙ H / H ∙∙∙ N 触点。通过密度泛函理论(DFT)计算进行了HOMO、LUMO的几何优化、电子性质和能级。定量静电势分析(ESP)和基于赫什菲尔德分区(IGMH)的独立梯度模型解释了四种吡唑类化合物中的活性氢键位点,并证实了其晶体结构中的氢键模式。

A facile high-yield, solvent-free approach for the synthesis of a series of 1-(hydroxymethyl)-pyrazoles under microwave irradiation was developed for the first time. The structures of four pyrazoles compounds were characterised by a single-crystal X-ray diffraction, and showed interesting intermolecular O‒H∙∙∙N hydrogen bonding linking two pyrazoles molecules to form R22(10) dimer architectures.
