New catalytic alkylation of in situ generated perfluoro-alkyloxy-anions and perfluoro-carbanions

Alkyl fluoroformates RHOC(O)F are a new family of excellent alkylating agents. Perfluoroacyl fluorides, selected perfluoroketones and fluoroolefins can be alkylated to hydrofluoroethers RF-O-RH and hydrofluoroalkanes RF-RH, respectively. Potassium fluoride and cesium fluorides catalysts in glymes at 50-100 °C are the preferred experimental conditions.
