Abstract :
Immobilization of molybdenum (VI) ions onto magnetic nanoparticles have been successfully prepared and applied for C–X cross-coupling reactions with aryl halides in green deep eutectic solvents. The results prove that the Fe3O4@SiO2−HNPABA−Mo(VI) magnetic nanoparticles show high catalyst activity and good stability. It was also revealed that this complex can be recycled up to five times without any significant loss in catalytic activity
