Abstract
The halide content of halogenated aromatic hydrocarbons such as PCBs can be reduced by treatment with a reagent comprising (i) at least one complex of a transition metal of group 4 or 5 with a multidentate or unidentate organic or inorganic ligand and (ii) a reducing agent. The reaction is conducted in the presence of an aliphatic or aromatic amine, optionally in the presence of an inert organic solvent.
