Alkyl fluoroformates RHOC(O)F are a new family of excellent alkylating agents. Perfluoroacylfluorides, 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.
