Anodic monofluorination of N-substituted 1,4-benzoxazinone derivatives in DME containing Et4NF · 4 HF using a divided cell and platinum plate electrodes provided the corresponding α-monofluorinated products selectively in good to moderate yields, while that of N-unsubstituted 1,4-benzoxazinone derivative gave the corresponding benzene ring fluorinated product selectively.
