Synthesis,characterization and electrochemistry of diferrocenyl-1,3-diene

利用正丁基锂与二氯二茂锆的反应产物二丁基二茂锆(ZrCp2Bu2)与二茂铁苯乙炔的环合、水解等反应,制备出新的标题化合物。采用红外光谱、核磁共振谱、质谱、元素分析等表征手段,对所合成的化合物的组成、结构进行了表征。并利用循环伏安实验中两个二茂铁基电位差的大小,判断出新化合物中两个二茂铁基的相互位置,确定了新分子的基本构型,为二茂铁基-1,3-丁二烯衍生物的合成和分子构型的鉴定提供了新方法。

A novel compound 1,4-diphenyl-2,3-diferrocenyl-1,3-diene was synthesized via the reaction of ferrocenylphenylacetylene with dibutylzirconocene.The molecular structure of 1,4-diphenyl-2,3-diferrocenyl-1,3-diene was identified by the FT-IR,NMR,MS,and elemental analysis.The relative location of ferrocenyl unit was determined by measuring the potential difference of two ferrocenyl radicals by the cyclic voltammetry.Thereby,the research work referred to in this paper will be helpful for the synthesis and characterization of ferrocenyl-1,3-diene.
