    Abstract: 我們報導了以綠色化學方式合成自身耦合產物,其單元為重要的有機光電小分子材料。合成不同種類的聯噻吩衍生物與具官能基的芳香環,其中最環保的是使用水作為溶劑且異質催化劑Pd/C可回收再使用。


    ;We report herein an operationally simple homocoupling reaction that targets on the green synthesis of organic-electronically important building blocks. A variety of synthetically useful bithiophene derivatives and functionalized biphenyls are efficiently prepared by a on-water and under-air protocol using recyclable Pd/C as catalyst. We find that Pd/C gives generally higher and cleaner homocoupling conversions than using Pd(OAc)2 in the cases of (hetero)aryl iodides since Pd(OAc)2 triggers more side reactions including dehalogenations and oligomerizations. Under the optimum conditions, a broad range of functional groups such as ester, ketone, aldehyde, nitrile, nitro group, chloride, and bromide are well tolerated. We expect present methodology would make a valuable synthetic contribution towards bridging green chemistry with thiophene-based organic materials.
