4,4″-Dimercapto-o-terphenyl as a precursor of macrocyclic compounds was prepared from o-terphenyl by chlorosulfonation and reduction. Eight macrocycles having sulfide moieties were synthesized from 4,4″-dimercapto-o-terphenyl. The thioethynyl compound, derived from 4,4″-dimercapto-o-terphenyl by introduction vinyl group and by addition of Br2 following dehydrobromination, gave a novel cumulene upon treatment with cupric acetate in THF/pyridine. The structures of macrocyclic products were determined by 1H and 13C NMR, IR, and mass spectroscopies, elemental analysis, and X-ray crystallographic analysis. UV–vis and fluorescence spectra, and cyclic voltammogram, were also acquired.
4,4″-二巯基邻联三苯作为大环化合物的前体,通过邻联三苯的氯磺化与还原反应制备。从4,4″-二巯基邻联三苯合成了含有硫醚基团的八种大环化合物。由4,4″-二巯基邻联三苯衍生出的硫乙炔化合物,通过引入乙烯基团和随后脱溴化氢加成溴后,在THF/吡啶中与醋酸铜处理得到一种新型累积多烯。大环产物的结构通过1H和13C核磁共振、红外、质谱、元素分析和X射线晶体学分析确定。还获得了紫外-可见光谱、荧光光谱和循环伏安图谱。
