The polychlorinated biphenyl congener 2,3,4,5,6-pentachlorobiphenyl and hexachlorobenzene were reductively dechlorinated in an aqueous biomimetic model system containing vitamin B{sub 12}. The products of 2,3,4,5,6-pentachlorobiphenyl dechlorination were 2,3,5,6- and 2,3,4,6-tetrachlorobiphenyl. Hexachlorobenzene dechlorinated to pentachlorobenzene and a mixture of 1,2,4,5- and 1,2,3,5-tetrachlorobenzene. The proton from water was shown to be the source of the hydrogen atom used for the replacement of chlorine on the biphenyl ring.
