investigated. Both derivatives were selectively fluorinated in good yields at the carbon α to the sulfur atoms in Et4NF·3HF/DME using a platinum anode and an undivided cell. The fluorination yields of the benzofuranone derivatives were improved by the addition of Ph2S, which was not effective in the case of the benzothiazole derivative. The fluorination yield of the benzothiazole derivative was strongly
