An organic‐inorganic hybrid heterogeneous nanocatalyst system was synthesized by covalent grafting a palladium dichloride complex of the type (L) 2 PdCl 2 (L=trimethoxysilyl‐functionalized triphenylphosphine) on silica‐coated magnetic nanoparticles. It is a highly active and recyclable catalyst for the Suzuki–Miyaura cross‐coupling reaction. The new catalyst can easily be separated from the reaction mixture by applying an external magnetic field and can be recycled many times without any loss of activity.
