Abstract: The aim of this study is to develop a. catalytic method which has advantages over current methods to detoxify and degrade environmentally harmful polychlorinated biphenyls (PCBs). A variety of catalysts have been employed in a preliminary study on 1,4-dibromobenzene and 4,4'-dibromobiphenyl which may be considered to represent simple analogues of PCBs. The most satisfactory catalysts are those involving (Pd(dppf)] [dppf = 1,1'-bis(diphenylphosphino)ferrocene], generated in situ from PdCl2(dppf) or Pd(dppf)2. In the presence of the reducing reagent, namely NaBH4, debromination has been achieved at relative mild conditions with high product yields (> 70%). Thus, our results indicate the possibility of dechlorination of PCBs with such catalysts.
