A highly efficient system composed of Pd-TPPTS [TPPTS: trisodium salt of tri(m-sulphonylphenyl)phosphine] and halogen-free ionic liquid ([Rmim][p-CH3C6H4SO3), R = methyl, ethyl, n-butyl, n-hexyl, n-octyl, n-dodecyl) has been established for Heck coupling of aryl halides with styrene. Most of the investigated substrates could give the complete conversions (> 95%) with the catalyst of 1 mol% at 110 degrees C. The resulting products can be easily separated from the ionic liquids by simple liquid-liquid extraction, and the catalyst immobilized by ionic liquids can be consecutively run five times without significant loss in catalytic activity.
