Fluorous Lewis acids and phase transfer catalysis
That’s the title of a recent review published in the journal Molecular Diversity. The review covers in good detail all of the work conducted using fluorous Lewis acids, primarily metal perfluorosulfonates such as Yb(OSO2C8F17)3, in catalyzing various reactions. Basically, any … Continue reading

Handbook of Asymmetric Heterogeneous Catalysis
One of the newest additions to Wiley’s “Handbook” series is the “Handbook of Asymmetric Heterogeneous Catalysis” that includes a chapter on asymmetric fluorous catalysis written by Prof. Gianluca Pozzi of the CNR-Istituto di Scienze e Tecnologie Molecolari in Milan, Italy. … Continue reading
Biphasic Biocatalysis By Adding Fluorosurfactants
A little more than a year ago, we published a post describing Prof. Neil Thomas’ work in fluorous biphasic biocatalysis. The key to this was that an enzyme, in this case ?-chymotrypsin mediated transesterification, could be rendered fluorous through non-covalent … Continue reading
Tris Rf8 compounds are hard to dissolve… but, that’s not so bad.
Recent Org Lett paper from Prof. Reiser and coworkers at Universität Regensburg, Germany, describes new fluorous TEMPOs that are used in oxidation of alchols to aldehydes. The structures are shown below. They initially prepared a fluorous TEMPO with one Rf8 … Continue reading
Immobilization of Fluorous Catalysts on Solids
The Journal of Fluorine Chemistry has published online an upcoming paper from Profs Jörg Tiller (Universität Dortmund) and Willi Bannwarth (Universtät Freiburg) describing ring closing metathesis using a fluorous Grubbs-Hoveyda catalyst immobilized on an amphiphilic polymer co-network (APCN). First what … Continue reading
