A facile synthetic approach to the direct preparation of 3-pyridylzinc bromide has been demonstrated using Rieke zinc with 3-bromopyridine in the presence of a catalytic amount of lithium chloride. A variety of different electrophiles have been coupled to give the corresponding cross-coupling products in moderate to good yields. Also, this methodology has been expanded to the preparation of the corresponding
已经证明在催化量的氯化锂的存在下,使用里克锌和3-溴吡啶,可以直接合成3-吡啶基溴化锌的简便合成方法。已经将多种不同的亲电试剂偶联,以中等至良好的产率得到相应的交叉偶联产物。同样,该方法已扩展到制备3-溴吡啶类似物的相应有机锌试剂。 3-吡啶基溴化锌-偶联反应-杂环衍生物
