The novel magnetic nanoparticle-supported bifunctional catalyst NH-Pd(0)@MNP was successfully prepared and evaluated in a one-pot tandem reaction, producing a series of biaryl derivatives under phosphine-free conditions. The catalyst can be easily separated using an external magnetic field and reused multiple times without significant loss of catalytic activity.
A novel magnetic nanoparticle-supported bifunctional catalyst NH-Pd(0)@MNP was prepared and its activity was evaluated in one-pot Suzuki coupling-Knoevenagel condensation tandem reaction. A series of biaryl derivatives were synthesized via sequential Suzuki coupling-Knoevenagel condensation in ethanol/water medium under phosphine-free conditions. Meanwhile, the catalyst could be easily separated by an external magnetic field, and could be reused several times without remarkable loss of catalytic activity.
