compounds (I) (C14H10N4) and (II) (C15H16N4) were synthesized with high yields from each reaction of benzylidene malononitrile with dichloride zinc directly in methanol or ethanol solvent . Both the compounds were characterized by NMR, IR, ESI, elemental analysis and single-crystal X-ray diffraction techniques. Investigation of intermolecular interaction via Hirshfeld surface analysis indicates that these
摘要 苯亚甲基丙二腈与二氯化锌直接在甲醇或乙醇溶剂中反应,分别以高收率合成了两种二氰基吡啶衍生物化合物(I)(C14H10N4)和(II)(C15H16N4)。两种化合物均通过 NMR、IR、ESI、元素分析和单晶 X 射线衍射技术进行表征。通过 Hirshfeld 表面分析对分子间相互作用的研究表明,这些密切接触主要归因于 NH…N 氢键。前沿分子轨道和自然键轨道(NBO)分析表明化合物(I)和(II)具有相对较高的动力学稳定性。作为一般类型的催化剂,在二苯甲酮-亚胺氰基硅烷化反应中进行反应活性,以80.0%和86的高产率获得更好的性能。
