我们首次证明了具有适当金尺寸和聚合物厚度的聚（2-氨基苯硫酚）稳定的金纳米粒子是水和空气中芳基卤与芳基硼酸的Suzuki-Miyaura交叉偶联反应的活性催化剂。用带有各种取代基的芳基卤化物或芳基硼酸可以获得高产率。这一新发现无疑将拓宽金纳米粒子在有机催化反应中的应用。
We have demonstrated that poly(2-aminothiophenol)-stablized gold nanoparticles with proper gold size and polymer thickness are active catalysts for Suzuki-Miyaura Cross-coupling reaction of aryl halides with arylboronic acids in water and air for the first time. High yields can be obtained with aryl halides or arylboronic acids bearing a variety of substituents. This new finding will undoubtedly broaden the application of gold nanoparticles in organic catalytic reactions.
