Pyrene-Tagged Ionic Liquids: Separable Organic Catalysts
for SN2 Fluorination
Posted on 2017-06-19 - 22:19
We prepared pyrene-substituted imidazolium-based
ionic liquids
(PILs) as organic catalysts for the SN2 fluorination using
alkali metal fluoride (MF). In this system, the PIL significantly
enhanced the reactivity of MF due to the phase-transfer catalytic
effect of the imidazolium moiety as well as the metal cation−π
(pyrene) interactions. Furthermore, this homogeneous catalyst PIL
was easily separated from the reaction mixture using reduced graphene
oxide by π–π stacking with the pyrene of PIL.
