| Abstract: | Dehalogenation of perhalogenated cyclohexanes C6Cl6F6, 1-azacyclohexenes C5Cl4F5N and bicyclo4.4.0]dec-1(6)-enes C10Cl8F8 in the vapour phase over iron filings at 350-500 °C and in solution with Zn and additivities (Cu, NiCl2·6H2O + bpy) at 80 °C (heterogeneous reaction) or with P(NEt2)3 at 20 °C (homogeneous reaction) was studied. In all cases, perfluoroarenes, chloroperfluoroarenes and dichloroperfluoroarenes (benzenes, naphthalenes and pyridines) were obtained in good overall yield. |
