We have designed and synthesized 1-substituted and 1,1′-disubstituted ferrocene-based unsymmetrical azines under metal-free conditions. The crystal structures of 3k, 5i, and 5g revealed that conjugative interactions between the ferrocene phenyl rings and the entire azine fragment exist. Furthermore, our electrochemical and optical analysis provided support for extended conjugation, which suggested a larger substituent effect in this system. Density functional theory calculations also supported the results. Thus, these results reflect a stronger conjugative interaction between the ferrocene phenyl rings and the entire azine fragment.

通过醛与酮衍生的N-甲苯磺酰Hy的简单反应合成二茂铁基不对称叠氮化合物,并评估分子的共轭程度
我们已经设计和合成了在无金属条件下的1取代和1,1'-二取代的二茂铁基不对称嗪。3k,5i和5g的晶体结构表明,二茂铁苯环与整个嗪片段之间存在共轭相互作用。此外,我们的电化学和光学分析为扩展的共轭提供了支持,这表明该系统具有更大的取代基效应。密度泛函理论计算也支持该结果。因此,这些结果反映出二茂铁苯环与整个嗪片段之间的共轭相互作用更强。
