Abstract: The catalyst [RuCl2(TPPTS)2]2 was used in the regioselective hydrogenation of quinoline in [Rmim][p-CH3C6H4SO3] with high conversion and selectivity. The products can be easily separated from the catalyst immobilized in ionic liquids by simple extraction with cycohexane. The conversion reached 86.0% when the catalyst was reused 6 times.
