Polymer-supported macrocyclic Schiff base palladium complex was prepared and characterized. The catalyst exhibits excellent catalytic activity and stability for Suzuki cross-coupling reaction under ambient condition. Various aryl bromides were coupled with aryl boronic acids in DMF/H2O, under air, in the presence of 0.1 mol% of the catalyst to afford corresponding cross-coupled products in high yields within 20-30 min. Furthermore, the heterogeneous catalyst can be readily recovered by simple filtration and reused several times without significant loss in its activity. (C) 2010 Elsevier B.V. All rights reserved.
