Abstract: Magnetite nanoparticles as efficient catalyst for C—O cross-coupling reaction of aryl bromide with phenol under solvent-free and ligand-free conditions were described. Under the optimized conditions:130 ℃, 48 h and 7% molar fraction of Fe3O4, the yield of diaryl ether reaches up to 94.7%. The separated magnetite nanoparticles catalyst can be recycled for 4 runs in the C—O cross-coupling reaction without significantly loss of catalytic activity.

Key words: cross-coupling, magnetic Fe3O4 nanoparticles, diaryl ether, arylation, recyclability
