    Site-selective mono-oxidative addition of active zinc into carbon–bromine bond of dibrominated-thiophenes: preparation of thienylzinc reagents and their applications
    摘要:
    A facile protocol for the preparation of 3-bromo-2-thienylzinc bromide A and 5-bromo-2-thienylzinc bromide B has been developed. It has been successfully accomplished by a site-selective oxidative addition of active zinc into a chemically pseudo-equivalent or equivalent carbon-bromine bond, respectively. The subsequent cross-coupling reactions of the organozincs were also successfully carried out under mild conditions providing the corresponding products in moderate to high yields.

  • New and efficient access to 3-substituted 2,5-dibromothiophenes. Consecutive nickel-catalyzed electrochemical conversion to thienylzinc species
    作者:Mohamed Mellah、Eric Labbe´、Jean Yves Ne´de´lec、Jacques Pe´richon
    DOI:10.1039/b006748m
    日期:——
    We have achieved the stepwise synthesis of 3-substituted thienylzinc reagents using both electrochemical methods and an original bromination procedure. For several compounds 3-bromothiophene was the starting substrate, which was functionalized according to recently developed electrochemical procedures. The nickel-catalyzed electrochemical reduction of the resulting 3-substituted 2,5-dibromothiophenes in the presence of zinc salts allowed the formation of monothienylzinc species in good yields. The selectivity of this reaction is discussed within the context of the electrochemical synthesis of regioregular polythiophenes.
    我们已经通过电化学方法和一种原创的化程序实现了3取代噻吩锌试剂的逐步合成。对于几个化合物,3-溴噻吩是起始底物,它根据最近开发的电化学程序进行了功能化。在盐存在下,对得到的3取代2,5-二溴噻吩进行催化的电化学还原,使得单噻吩物种以良好的产率形成。关于该反应的选择性,我们在电化学合成有规聚噻吩的背景下进行了讨论。
