The Core‐Shell Magnetic Mesoporous Microspheres Immobilized NHC‐Palladacycles: An Efficient and Recyclable Catalyst for Suzuki–Miyaura Cross‐Coupling of Pharmaceutical Synthesis

Herein, the core-shell magnetic mesoporous microspheres immobilized N-heterocyclic carbene-palladacycles catalyst with constrained aliphatic linkers (Fe3O4@mSiO2@NHC−Pd) were successfully prepared, achieving high catalyst loading, outstanding catalytic activity, and multiple reusability without a significant decrease in catalytic performance even after 12 cycles for the Suzuki-Miyaura cross-coupling reaction of aryl chlorides and aryl boronic acids.
