摘要： 报道了一种制备聚苯乙烯紫精树脂的新方法。首先将氯甲基化聚苯乙烯树脂与4.4'-联吡啶反应,将联吡啶结构引入树脂骨架,然后与氯化苄反应得到含紫精结构的树脂。将所得树脂作为电子转移催化剂应用于邻氯硝基苯还原。结果表明:含紫精结构的树脂具有在室温下诱导邻氯硝基苯还原生成邻氯苯胺的功能,催化活性与其结构有关,树脂可重复使用。

Abstract: Anew method for preparing polystyrylviologen resins was reported in this paper.The polystyrylviologen resins were obtained by the reactions of chloromethylated polystyrenewith 4,4'-bipyridine,then with benzyl chloride.The obtained resins were used as electron-transfer catalysts in the reduction of 2-chloronitrobenzene.Experimental results showed thatthe resins with viologen moieties have abilities to mediate the reduction of 2-chloroni-trobenzene at room temperature,affording 2-chloroaniline,and the structure of the resinscan also affect their electron-transfer catalytic activities. The resins can be reused.

Key words: Polystyrylviologen resin, Electron-transfer catalyst, Reduction, 2-Chloroni-trobenzene
