An unprecedented method for the palladium (II)-catalyzed direct halogenation of benzothiadiazole derivatives is reported here, which would allow the rational tuning of their electronic properties by further transformations. The key strategy is the combination of the double functions of benzothiadiazole as both an important moiety of functional materials and modifiable directing group. Various mono/polychlorinated
本文报道了一种空前的钯(II)催化苯并噻二唑衍生物直接卤化的方法,该方法可以通过进一步转化合理地调节其电子性能。关键策略是结合苯并噻二唑的双重功能,这既是功能材料的重要组成部分,又是可修饰的导向基团。可以有效地制备各种单/多氯代,溴代或碘代苯并噻二唑产品,这些产品可以转化为多种有价值的多芳族化合物,并在材料化学中具有潜在的应用。
