Abstract

Modified Binh Thuan bentonite catalyst was prepared by exchanging with aqueous solution of PdCl2, giving a catalyst loading of 0.14 mmol of Pd/g (AAS). The Pd2+ - exchanged bentonite effectively catalyzed the Heck carbon-carbon coupling reaction between iodobenzene and styrene. The reaction was performed using 0.5 mol% catalyst at 120 oC in dimethylformamide (DMF) in the presence of Na2CO3 as a base, affording the coupling products in excellent conversions (GC). It was also observed that the catalyst could be facilely separated from the reaction mixture and could be reused in subsequent reaction without significant degradation in activity.
