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.
烷基氟甲酸酯R H OC(O)F是一种新型的优异烷基化剂。全氟氟化物,选择perfluoroketones和氟烯烃可被烷基化,以氢氟醚- [R ˚F -O-R ħ和氢氟烷烃- [R ˚F -R ħ,分别。甘氨酸中的氟化钾和氟化铯催化剂在50–100°C是优选的实验条件。
