The syntheses by transition metal coupling reactions of a large number of oligomers constructed from benzene and thiophene rings are described. The first use of arylcadmium chlorides for such coupling reactions is reported. The routes chosen allow for rational variation in the modes of linkage, the substitution and the proportions of the two units. The benzene and thiophene rings are always joined
描述了通过过渡金属偶合反应合成由苯和噻吩环构成的大量低聚物。据报道,芳基氯化镉首次用于这种偶联反应。选择的途径允许在连接方式,取代和两个单元的比例方面进行合理的变化。苯环和噻吩环始终以已知顺序连接,并且可以带有各种规则间隔的官能团。另外,低聚物的形状可以任意改变。在所有情况下,碘或氯化铁的p型掺杂都会导致电导率大大提高。
