Abstract A novel magnetically recoverable functionalized magnetic(Fe 3 O 4 ) nanoparticle supported-nickel(II) complex with a high surface area has been synthesized by chemical conjugation of magnetite nanoparticles with highly reactive silanols on the surface of magnetic Fe 3 O 4 to improve the affinity of Fe 3 O 4 nanoparticles for the target species. Functionalized Ni(II) complex containing surface of pyridine, methoxysilanyl and amino groups. Studies revealed that Fe 3 O 4 @[Ni(bpy) 2 (py-tmos)] is a new and highly efficient green catalyst for the synthesis of a diverse range of 3,4-dihydropyrimidin-2(1 H )-ones under solvent free conditions, and in addition Fe 3 O 4 @[Ni(bpy) 2 (py-tmos)] could be easily recovered by a simple magnetic separation and recycled at least 5 times without deterioration in catalytic activity.
