The preparation of mixed thiophene/furan oligomers with alkyl groups at α,α′-position by the method which we discovered recently in our lab is presented. Thus, the mixed thiophene/furan oligomers can be prepared in good yields from monoiodoarene in the presence of 5 mol % of palladacycle catalyst and 1.2 equiv of N,N-diisopropylethylamine in DMF at 100°C for 8 h.
介绍了采用本实验室最近发现的方法制备α,α'-位烷基的噻吩/呋喃混合低聚物。因此,在 5 mol% 的钯环催化剂和 1.2 当量的 N,N-二异丙基乙胺在 DMF 中在 100°C 下 8 小时,可以以良好的产率从单碘芳烃制备混合噻吩/呋喃低聚物。
