3,6-Diethylphthalonitrile (3) with a tetrathiafulvalene (TTF) unit at 4,5-positions was prepared from 4,5-xylylenedithio-3,6-diethylphthalonitrile (1a) via elimination of the xylylene group, connection of a carbonyl group to benzenedithiolate generated, and condensation of 4,5-bis(methylthio)-1,3-dithiole-2-thione with benzo-1,3-dithiole-2-one (2-O) produced. A 1:1 mixture of phthalonitrile (3) and
在 4,5-位具有四硫富瓦烯 (TTF) 单元的 3,6-二乙基邻苯二甲腈 (3) 是由 4,5-二甲苯二硫基-3,6-二乙基邻苯二甲腈 (1a) 通过消除二甲苯基团、连接羰基而制备的生成苯二硫醇,并生成 4,5-双(甲硫基)-1,3-二硫醇-2-硫酮与苯并-1,3-二硫醇-2-酮 (2-O) 的缩合反应。邻苯二甲腈 (3) 和 4,5-双(苄硫基)-3,6-二乙基邻苯二甲腈 (1b) 的 1:1 混合物在 120°C 下用锂在正己醇中处理,生成六(苄硫基)单(四硫富瓦烯)酞菁 (5)、四(苄硫基)双(四硫富瓦烯)酞菁(6)和双(苄硫基)三(四硫富瓦烯)酞菁(7)。5、6和7的结构通过1H NMR、FAB MS、MALDI-TOF MS(基质辅助激光解吸电离飞行时间质谱)确定,和紫外-可见光谱。化合物6是反式和顺式异构体(6-反式和6-顺式)的混合物。通过添加三氟乙酸 (TFA),在氯仿中测量的
