The use of heterogeneous bimetallic Pd‐based nanocatalyst for directing the inactivated sp³ C−H coupling has been scarcely explored. This work reported the formation of symmetrical C−C bonds from the inactivated sp³ C−H bonds catalyzed by employing reduced graphene oxide supported PtPd@Pt porous nanospheres. The reaction of sp³ C−H activation proceeded under mild conditions without any solvent, ligand or directing group. It is a higher atom‐, step‐ and cost‐effectiveness strategy for developing heterogeneous catalysts in the synthesis of bibenzyls with various functional groups (e. g. aryl, alkyl, methoxyl, halogen, ester, and pyridyl).

还原性氧化石墨烯负载的PtPd @ Pt多孔纳米球催化的非偶合基团sp3 C–H活化，通过均相偶合合成联苄。

很少探索使用非均相双金属钯基纳米催化剂指导失活的sp ³ C-H偶联。这项工作报道了通过使用还原性氧化石墨烯负载的PtPd @ Pt多孔纳米球催化的灭活的sp ³ C-H键形成对称的C-C键。sp ³ C H活化反应在温和条件下进行，没有任何溶剂，配体或指导基团。在合成具有各种官能团（例如芳基，烷基，甲氧基，卤素，酯和吡啶基）的联苄中，开发多相催化剂是一种更高的原子，步骤和成本效益策略。
