Electrochemical fluorination of 2-quinolyl and 4-(7- trifluoromethyl)quinolyl sulfides bearing an electron-withdrawing group at the position α to the sulfur atom was studied. Fluorination was successfully carried out using Et4NF·nHF (n = 3, 4) and Et3N·3HF as a supporting electrolyte and a fluoride ion source in dimethoxyethane in a divided cell to provide the corresponding α-fluorinated sulfides in good yields. A trifluoromethyl group positioned on the quinoline ring significantly enhanced anodic α-fluorination. 4-(Methylthio)-7-(trifluoromethyl)quinoline was also found to undergo anodic fluorination efficiently. Solvent effects of various donor numbers were also established.
