A range of functionalised symmetrical and unsymmetrical tetrathiafulvalene (TTF) derivatives containing substituted 4,5-(propylenedithio)-1,3-dithiole units has been prepared. Key half-units are the t-butyldiphenylsilyl-protected 1,3-dithiole derivative 18 and the ketal-protected derivative 32. Self-coupling and cross-coupling reactions of these half-units, with 1,3-dithiole-2-one and -2-thione derivatives
制备了一系列含有取代的4,5-(丙烯二硫基)-1,3-二硫醇单元的官能化对称和不对称四硫富瓦烯(TTF)衍生物。关键的半单元是叔丁基二苯基甲硅烷基保护的1,3-二硫醇衍生物18和缩酮保护的衍生物32。在亚磷酸三乙酯的存在下,这些半单元与1,3-二硫代-2-酮和-2-硫酮衍生物19-22的自偶联和交叉偶联反应发生。脱保护后,TTF衍生物14,24,28,34和40-43中,获得轴承羟基或酮官能团。14,24和28的一个或多个醇基团的官能化用酰氯和异氰酸酯已经获得了化合物16、17、25、26和29。循环伏安研究表明,新的TTF衍生物是有效的π电子供体。它们经历了两个可逆的单电子氧化还原波。4,5-(2-羟基丙烯二硫基)-1,3-二硫基-2-硫酮3和缩酮蛋白的X射线晶体结构
