  一种新的、简单的 3-芳基噻吩路线

  摘要：

  3-芳基噻吩由 2,5-二氯噻吩分两步制备。在温和条件下，2,5-二氯噻吩与各种芳香族化合物在温和条件下发生区域选择性反应，得到 4-芳基-2-氯噻吩。后一种化合物很容易通过催化脱氯以良好的产率转化为相应的 3-芳基噻吩。

  4-diaryl- and 2,3-diarylthiophenes were synthesized from 2,5-dichlorothiophene via 4-aryl-2-chlorothiophenes in two and four steps including Ni-mediated cross-coupling, respectively. Aluminum chloride-catalyzed reaction of 3-aryl-2-chlorothiophenes with some aromatic ethers unexpectedly led to the formation of the corresponding 2,4-isomers.

  3,4′-Diaryl-, and 4,4′-diaryl-2,2′-bithienyls, new classes of mixed thiophene–arene oligomers, were synthesized from 2,5-dichlorothiophene via 4-aryl-2-chlorothiophene in three and two steps, respectively. Namely, a Friedel–Crafts type self-condensation of 4-aryl-2-chlorothiophene, followed by catalytic dechlorination, yielded unsymmetrical bithienyls. Homocoupling of 4-aryl-2-chlorothiophene using
