By using a chalcogenolate (thiolate or selenolate) protection–deprotection strategy, a series of singly bridged bis-TTFs, 3a–c, 4a, have been prepared in high yield (84–96%) through two different routes. Route 2, involving the reaction between a monochalcogenolate TTF derivative with a previously prepared monoiodinated TTF species, appears to be a very useful and general strategy to selectively prepare
通过使用硫族油酸酯(硫醇盐或硒醇盐)保护-脱保护策略,已通过两条不同的路线以高收率(84-96%)制备了一系列单桥双TTFs 3a – c,4a。路线2涉及单硫属元素化物TTF衍生物与先前制备的单碘化TTF物种之间的反应,这似乎是一种非常有用且通用的策略,可以选择性地高收率制备双TTF(84-90%)。双-的TTF, 图3a - Ç,4A,很容易转化成相应的二甲基化衍生物3A ' - ç ',4a中在基本(2当量)IMe介质中。该系列的双-TTF的给电子能力已经通过循环伏安法测定。供体3a,4a,3a' – c '的几种盐(主要是高氯酸盐)已通过电镀电合成获得为黑色粉末。已测量了它们在室温下作为压制粉末药丸的电导率,以及ESR信号的温度依赖性。
