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

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
