An Efficient Pd/Al(OH)3 Nanoparticle Catalyst for Suzuki Coupling Reactions of Aryl Halides

Abstract A high-performance palladium-based Pd/Al(OH) 3 catalyst has been prepared by the one-pot three-component method. It was found that this ‘ligandless’ Pd/Al(OH) 3 catalyst showed remarkable reactivity and gave excellent yields (up to 99%) towards the condensation of aryl bromides with various arylboronic acids under mild conditions, and afforded good yields of the coupling products (up to 97%) with most aryl chlorides in two different catalytic systems. Furthermore, this catalyst could be easily recovered through filtration and reused for 8 cycles without significant loss of the yield.
