摘要：

Polychlorobiphenyls are completely dechlorinated to biphenyl by a polymethylhydrosiloxane-alkali metal system at ambient conditions. Dechlorination proceeded via the formation of a polychlorobiphenyl radical anion, which cleaved with a regioselectivity similar to that normally observed in nucleophilic substitution of polyhaloarenes.
