摘要：

Pd-catalyzed reductive debromination of highly brominated benzenes is studied as a model for degradation of polybrominated biphenyls (PBBs). A complete conversion of hexabromobenzene to benzene at room temperature has been achieved. Both PdCl2[(C5H4PPh2)(2)M] (M = Fe, Ru) show excellent catalytic activities in the presence of NaBH4 as a reducing agent and Me2NC2H4NMe2 as a base. (C) 1997 Elsevier Science B.V.
