situ desilylation avoids the manipulation of the sensitive terminal dialkynes (HC≡CArC≡CH), whilst the general approach presented has some advantages over alternative synthetic strategies based on coupling of aryl dihalides (XArX) by avoiding the multi-step preparation and purification of the terminal alkynes S-(4-ethynylphenyl) ethanethiolate, 4-ethynylthioanisole and 5-ethynyl 3,3-dimethyl-2,3-dih
通过受保护的双(炔烃)Me 3 SiC≡CArC≡CSiMe 3 (Ar = 2,5-噻吩基、1,4-萘基、9,10-蒽)和随后的 Sonogashira 与S-(4-碘苯基)乙硫醇盐、4-碘硫代苯甲醚或 5-溴-3,3-二甲基-描述了2,3-二氢苯并[ b ]噻吩。现场的去甲硅烷化避免了对敏感末端二炔烃 (HC≡CArC≡CH) 的操作,而所提出的一般方法通过避免末端的多步制备和纯化,与基于芳基二卤化物 (XArX) 偶联的替代合成策略相比具有一些优势炔烃S- (4-ethynylphenyl) ethanethiolate, 4-ethynylthioanisole 和 5-ethynyl 3,3-dimethyl-2,3-dihydrobenzo[ b]噻吩。使用扫描隧道显微镜断裂连接 (STM-BJ) 方法确定了所得硫醇盐或硫醚官能化 OAE 分子线的分子电导。尽管分子长度相当相似
