Abstract Heterogeneous homocoupling reactions of phenylboronic acids were greatly accelerated via Suzuki homocoupling reactions. In this work, a tandem route was designed which firstly one part of phenylboronic acids reacted with iodine to form iodobenzenes, then another part of phenylboronic acids coupled with iodobenzenes to produce biaryl compounds. The tandem reaction were catalyzed by a bifunctional heterogeneous catalyst of metal organic frameworks encapsulated with palladium nanoparticles (Pd@MOFs). This strategy for forming symmetric C-C bond between benzene rings has obvious advantages such as high efficiency, easy separation, good recyclability and no addition of toxic halogenated benzene.

钯纳米颗粒包覆的金属有机骨架催化 Suzuki 均偶联反应合成联芳基化合物

摘要 Suzuki 均偶联反应极大地加速了苯基硼酸的非均相偶联反应。在这项工作中，设计了一种串联路线，首先一部分苯基硼酸与碘反应生成碘苯，然后另一部分苯基硼酸与碘苯偶联生成联芳基化合物。串联反应由包封有钯纳米颗粒（Pd@MOFs）的金属有机骨架的双功能多相催化剂催化。这种在苯环之间形成对称CC键的策略具有效率高、易于分离、可回收性好、不添加有毒卤代苯等明显优点。
