Supported Ionic Liquids and Ionic Catalysts for Continuous Biphasic Reactions

Biphasic olefin metathesis
The replacement of one triflate ligand in the standard systems by betaine-type ligands led to catalysts that could be applied in olefin metathesis reactions under biphasic conditions in a mixture of pyrrole and heptane. The biphasic reaction setup offers access to metal free products, which are of high importance in, for example, pharmaceutical industry.
