and the corresponding ruthenium(II) complexes were synthesized in high yields. The TMSE-protected thiol-functionalized RuII(tpy) complexes can be readily converted into the corresponding ruthenium(II) complexes with an acetyl group by using AgClO4/acetyl chloride or TBAF/acetyl chloride. Based on this convenient synthetic approach under mild conditions, the ruthenium(II) complex [(AcSCH2C6H4tpy)(PPh
合成了一系列具有保护基团的硫醇官能化三联吡啶 (tpy),如乙酰基 (Ac)、2-(三甲基甲硅烷基)乙基 (TMSE) 和叔丁基 (tBu),以及相应的钌 (II) 配合物。高产量。通过使用 AgClO4/乙酰氯或 TBAF/乙酰氯,可以很容易地将 TMSE 保护的硫醇官能化 RuII(tpy) 配合物转化为相应的带有乙酰基的钌 (II) 配合物。基于这种在温和条件下方便的合成方法,成功地获得了钌(II)配合物[(AcSCH2C6H4tpy)(PPh3)2Ru(C≡CC6H4C≡CC6H5)](ClO4)[12](ClO4)}与乙酰硫基-tpy通过三步合成程序。以4'-4-[(乙酰硫基)甲基]苯基}-2,2':6',2"-三联吡啶为螯合配体,制备了双核双氰胺连接的钌配合物,表征了,并固定在金电极表面以形成自组装单层(SAM)。这些化合物通过质谱、IR、1H NMR 和 13C NMR 或
