Outlook for Fluorous Solvents and Ionic Liquids

Not very long ago, ionic liquids (ILs) were just considered as potential alternative solvents for multiphasic reactions and were mentioned in the outlook chapter of books dealing with this area, whereas water was already industrialized in key transition metal catalyzed processes [2]. ILs have now attracted more interest It is possible to buy them, which probably promotes their use, and there are more and more physical data available on these solvents. The range of reactions that have been described in these media is probably wider than in SCCO2 or fluorous solvents. But it would not be reahstic to assume that all catalyzed reactions can be transferred to ILs with benefits. The advantages of using ILs have been well described for some reactions which have been reported in this book, and just a few of them have been run on micro-pilot or pilot scale.
