Abstract

To alleviate the problem of solid salt precipitation when using inorganic bases in cross-coupling reactions, basic anions were combined with the trihexyl(tetradecyl)phosphonium ([P66614]+) cation to ensure an ionic liquid byproduct. If the starting base is also an ionic liquid, as is the case for [P66614][OH]·4MeOH, it can be used as both base and solvent.
