Abstract

The Stille coupling reaction has been performed in 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM BF4), a room-temperature ionic liquid (RTIL). Use of this solvent system allows for facile recycling of the solvent and catalyst system, which can be used at least five times with little loss in activity. An interesting preference in starting catalyst oxidation state for use with aryl bromides and aryl iodides was observed.
