Fan, Ao published the artcilePhosphonium ionic liquids as highly thermal stable and efficient phase transfer catalysts for solid-liquid Halex reactions, SDS of cas: 350-30-1, the publication is Catalysis Today (2012), 198(1), 300-304, database is CAplus.
Trihexyl (tetradecyl) phosphonium tetrafluoroborate was found to be an active catalyst for the introduction of fluoride by nucleophilic aromatic substitution. With a decomposition temperature above 300 °C, this ionic liquid is suitable for reactions at high temperatures The addition of 1 mol% of the ionic liquid relative to KF increased the initial rate for the fluorination of 1,2-dichloro-4-nitrobenzene six-fold compared to the uncatalyzed reaction. The highest reaction rate was observed at 20 mol% ionic liquid relative to KF. Ease of handling without the need for stringent drying conditions and reuseability make this ionic liquid a useful phase transfer catalyst.
