• Nanocrystalline Titania-Supported Palladium(0) Nanoparticles for Suzuki-Miyaura Cross-Coupling of Aryl and Heteroaryl Halides
  作者：B. Sreedhar、Divya Yada、P. Surendra Reddy

  DOI：10.1002/adsc.201100012

  日期：2011.10

  The Suzuki cross-coupling reaction of various aryl and heteroaryl halides with arylboronic and heteroarylboronic acids was studied using a titania-supported palladium(0) catalyst at room temperature under air. The conversion and selectivity results obtained for many substrates were excellent and similar to those provided by more active or even homogeneous catalysts. The methodology is similarly effective

  使用二氧化钛负载的钯（0）催化剂在室温下于空气中研究了各种芳基和杂芳基卤化物与芳基硼酸和杂芳基硼酸的Suzuki交叉偶联反应。对于许多底物，获得的转化率和选择性结果极好，与活性更高甚至均相的催化剂所提供的结果相似。使用2-溴-3,4,5-三甲氧基苯甲醛作为偶合伙伴，该方法同样有效，并获得了高收率的产品。此外，已表明其可用于合成三联苯和四联苯。通过简单的过滤从反应中定量回收催化剂，并重复使用多个循环，而活性没有明显损失。
