Abstract A series of conformationally constrained 2,6-bisferrocenylphenyl thioethers were synthesized via Suzuki–Miyaura cross coupling reactions. Structural information was obtained using X-ray crystallography and dynamic 1H NMR spectroscopic studies, showing highly constrained m-terphenyl systems. Interaction of the ferrocene moieties through space mediated by the sulfur were studied by ultra-violet
摘要通过Suzuki-Miyaura交叉偶联反应合成了一系列构象受限的2,6-双二茂铁基苯基硫醚。结构信息是使用X射线晶体学和动态1H NMR光谱研究获得的,显示出高度受限的间三联苯系统。通过紫外光电子能谱(UPS),循环伏安法,微分脉冲伏安法,UV-Vis-NIR光谱法和DFT计算研究了二茂铁部分通过硫介导的空间相互作用。电化学结果显示二茂铁的两个完全可逆的1e-氧化还原过程,其中峰的分离受溶剂和支持电解质的影响,表明存在显着的静电相互作用,这在UPS研究中已得到进一步证实。
