| Abstract: | Catalytic properties of AlBr3, AlBr3–CuCl2 and AlBr3–NiSO4 in liquid-phase conversion of butane and pentane have been examined. A possibility for the oxidative condensation has been revealed due to both the stoichiometric reduction of Ni2+ and Cu2+ ions entering into the composition of superacid catalysts, and the catalytic oxidation in the presence of bromine as an oxidant. Nature of the centers responsible for the oxidative condensation of lower paraffins is discussed.
