Abstract

Electrochemical anodic oxidation method for the incorporation of fluorine atom into quinoline ring is described. Our method involves a regioselective 5,8-difluorination of quinolines using HF:pyridine as a reagent/supporting electrolyte in an undivided electrochemical cell equipped with platinum anode and cathode. Various quinoline derivatives were subjected to electrolytic fluorination at room temperature to obtain moderate to good yields in short reaction time.
