including molecules incorporating dithiafulvene, dicyanoethylene, dihydroazulene, fulleropyrrolidine, and triazole units, and successfully subjected to a BiIII promoted conversion into products with thioacetate end-cap(s). The azide group could also withstand these conditions, which allowed us to prepare S-(4-azidophenyl) ethanethioate that presents a convenient building block for subsequent CuAAC reactions
硫代乙酸酯基团被广泛用作锚定基团,用于将分子连接到金表面或分子电子学中的电极之间。由于其易于水解,因此通常将其掺入相应的叔丁基硫醚合成序列的最后一步。在这里,我们提出了一种特别方便的方法,将 AcCl 与 Bi(OTf)3 结合使用,Bi(OTf)3 被称为对环境友好的盐。制备了多种具有叔丁基硫醚封端的氧化还原活性和光活性底物,包括结合二硫富烯、二氰基乙烯、二氢薁、富勒吡咯烷和三唑单元的分子,并成功地进行了 BiIII 促进转化为具有硫代乙酸酯封端。叠氮化物组也可以承受这些条件,
