Polymer-Supported Ammonium Fluoride: A Useful Reagent for Si-O Bond Cleavage.

Abstract Polymer-supported ammonium fluoride (1) is a convenient reagent for Si-O bond cleavage. Resin 1 is inexpensive, easy to prepare from commercial amine-containing anion exchange resins and aqueous hydrofluoric acid, easy to store. The product is easily separated from the reaction mixture by filtration. The used resins can be regenerated and reused without losing its reactivity.
