Abstract
A nickel boride reagent, prepared in situ by the reaction of nickel ch loride with sodium borohydride, has been used to hydrodechlorinate and hydrogenate chloroaromatic compounds. The same reagent can also dechl orinate chloro-olefinic compounds but chloroalkanes do not react. The reactions can be sustained by addition of hydrogen gas and the ratio o f the aromatic to aliphatic hydrocarbons produced can be varied by add ition of sodium hydroxide to the reaction mixture and by the duration of the reaction. The reactivity of polychlorinated biphenyls (PCBs), p olychlorinated naphthalenes (PCNs), chlorobenzene and tetrachloroethyl ene have been studied. Capillary gas chromatography was used to follow the course of reactions and gas chromatography-mass spectroscopy (GC- MS) was used for product identification.
