The study accelerated heterogeneous homocoupling reactions of phenylboronic acids via a tandem route utilizing a bifunctional heterogeneous catalyst of metal organic frameworks encapsulated with palladium nanoparticles. This strategy successfully formed symmetric C-C bonds between benzene rings, demonstrating advantages such as high efficiency, easy separation, good recyclability, and no addition of toxic substances.
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.
