SelectfluorTM on a PolyHIPE Material as Regenerative and Reusable Polymer‐Supported Electrophilic Fluorinating Agent
Résumé
The first recyclable polymer‐supported electrophilic fluorinating agent was prepared by reaction of molecular fluorine with the triethylenediamine motif that is grafted onto a poly(4‐vinylbenzyl chloride‐co‐divinylbenzene) polyHIPE material. The resulting polymeric SelectfluorTM‐type reagent demonstrated high efficiency in the fluorination of naphthol in the course of repeated sequences of fluorination and regeneration. It also reacted with the enol form and the sodium enolate of 1,3‐dicarbonyl compounds.
