Graphical Abstract
Eine einfache und hoch effiziente Variante der Friedel-Crafts-Alkenylierung von Arenen beruht auf dem Einsatz eines Metalltriflat-Katalysators in einer ionischen Flüssigkeit (siehe Schema, bmim=1-Butyl-3-methylimidazolium, Tf=Trifluormethansulfonyl). So wird die katalytische Aktivität deutlich erhöht und die Bildung von Nebenprodukten zurückgedrängt. Mit diesem System gelangen einige Reaktionen, die in gängigen organischen Lösungsmitteln nicht möglich sind.

- 10In sharp contrast to these results, only very small amounts of the alkenylated product was obtained (<2 % yield) in the hydrophilic ionic liquids, [bmim][BF4] or [bmim][OTf].
- 11Recently, Rogers and co-workers reported the instability of the ionic liquids’ counterion PF6 towards moisture, which resulted in hydrolysis and the formation of HF (R. P. Swatloski, J. D. Holbrey, R. D. Rogers, Green Chem. 2003, 5, 361). Therefore, to examine the possible catalytic effect of HF on this reaction, we also carried out the reaction only in [bmim][SbF6] or in a mixture of [bmim][SbF6] and water (1:1, v/v) without any metal triflate catalyst. However, the reaction did not occur at all.
- 12A new synthetic route to alkenylated arenes involving Pd- and Pt-catalyzed addition of arenes to alkynes in the presence of trifluoroacetic acid was recently reported:
