摘要
In this work, we described a methodology to immobilize Salen Pd (II) complex on the surface of magnetite nanoparticles. The palladium catalyst exhibited efficient catalytic activity in coupling reactions with aryl iodides or bromides and phenylboronic acid at 100 degrees C for 1-3 h under DMF/H2O. Furthermore, the catalyst could be magnetically isolated with a permanent magnet and the yields achieved above 85% after reused at least 5 times.
