The synthesis and X-ray structure of a new and readily available exTTF derivative (6) bearing a methyltriphenylphosphonium bromide moiety as a new buildingblock for the construction of electroactive molecules is reported. The phosphonium salt 6, which was prepared in one step from 2-hydroxymethyl-exTTF as a stable yellow solid in 84 % yield, efficiently undergoes Wittig olefination reactions with
报道了带有甲基三苯基溴化鏻部分的新型易得 exTTF 衍生物 (6) 的合成和 X 射线结构,作为构建电活性分子的新构件。鏻盐 6 在一步中由 2-羟甲基-exTTF 制备为稳定的黄色固体,产率为 84%,有效地与各种醛进行 WiTTig 烯化反应,主要形成 E 异构体。新型化合物的电子光谱和循环伏安法揭示了电活性单元之间的电子通讯。
