fluorodesulfurization of 3-aryl-2-phenylthio 2H-benzo[b][1,4]oxazine derivatives was successfully carried out using various N-halogenosuccinimides as oxidizing reagent in the presence of Et 3 N·3HF to provide the corresponding monofluorinated products in excellent yields. Selective fluorodesulfurization of the corresponding pyrido[3,2-b][1,4]oxazine derivatives was also achieved similarly.
