novel strategy for the synthesis of well-defined oligo(phenylenevinylene)s was developed. The procedure is entirely based upon two coupling processes, both involving vinyltrimethylsilanes. Bis(styryl)benzenes 2a-g bearing two octyloxy groups in the central aromatic ring and various substituents on the external aromatic rings were prepared in good yield by a regio- and stereoselective coupling reaction of
开发了一种合成明确定义的低聚(亚苯基亚乙烯基)的新策略。该程序完全基于两种偶联过程,均涉及乙烯基三甲基硅烷。通过1与不同的芳构氮杂四氟硼酸酯的区域和立体选择性偶联反应,以高收率制备了在中心芳环上带有两个辛氧基并且在外芳环上带有多个取代基的双(苯乙烯基)苯2a-g。通过将不饱和三甲基甲硅烷基衍生物3a,c,d转化为相应的硼衍生物并随后与化合物偶联反应,也可以容易地获得具有更扩展的共轭体系4a-c和间亚亚苯基13a,b的低聚物。 2a和2c。
