Selective fluorination of adamantanes was achieved by the electrochemical fluorination method, using Et3N−5HF as electrolyte and a fluorine source. Mono-, di-, tri-, and tetrafluoroadamantanes were selectively prepared from adamantanes by controlling the oxidation potential, and the fluorine atoms were introduced selectively at the tertiary carbons. Adamantanes that have functional groups such as ester

The directfluorination reaction of the functionalized adamantanes was achieved by using BrF3. In the reaction with methyl adamantane-1-caroxylate 1 and dimethyl adamantane-1,3-dicarboxylate 3, three and two fluorine atoms, respectively, were introduced selectively to their tert-carbons. On the other hand, in the reactions with 1-acetoxymethyladamantane 5, and 2-adamantanone 9, not only the expected
