Abstract

Fluorination reaction of epoxides and alkyl mesylates can be effectively achieved by reaction with Et3N˙3HF under microwave irradiation. The reaction time could be greatly reduced compared to the reaction under thermal conditions. The reactions were completed in a few minutes and the use of large excess of reagents could be avoided.
