Noble‐metal free Suzuki–Miyaura reaction catalyzed by magnetically recyclable MOF composites

Abstract

An effective metal–organic frameworks composite, Cu‐BTC@Fe3O4, was applied to catalyze Suzuki–Miyaura reaction under mild conditions and could achieve a good yield up to 98%. This magnetic noble‐metal free catalyst was proved excellent reusability for at least four cycles without loss of catalytic activity and crystallinity. X‐ray photoelectron spectroscopy confirmed that the binding energy of Fe‐2p shifted to a negative value by 0.3 eV in Cu‐BTC@Fe3O4 after catalysis; in the meantime, the binding energy of Cu‐2p shifted to a positive value by 0.1 eV. A possible bimetallic catalytic mechanism involved in this coupling reaction was proposed. In addition, the heterogeneous and recyclable properties of the catalyst were shown by hot filtration experiments, and the catalyst can be easily separated from reaction system in the presence of magnetic field.

In situ construction of halogen MOF bifunctional catalysts for synergistic removal of NO and Hg0

“…35 O α plays a crucial role in NO reduction and has high activity in NH 3 -SCR reactions due to its high mobility. 36 Therefore, halogen-modified Cu-Ce-BTC catalysts have great potential in NH 3 -SCR reactions. 37 Fig.…”

Magnetic nanoparticle-decorated metal organic frameworks for chemiluminescence detection of glutathione

“…Fe 3 O 4 nanoparticles (Fe 3 O 4 NPs) have peroxide activity and could be recycled and reused by magnets as a biocompatibility magnetic material [33,34]. There have also been reports of Fe 3 O 4 NPs combined with MOFs to form composites [35][36][37][38]. Zhang's group used the synthesized composite Cu-BTC@Fe 3 O 4 to catalyze the Suzuki-Miyaura reaction under mild conditions with good catalytic activity [35].…”
