Abstract

Direct fluorination of adamantanes was achieved by iodine pentafluoride and one or two fluorine atoms were introduced selectively on the tertiary carbons of adamantanes.

8

More than one fluorine atom of IF5 is used and one equivalent of IF5 is not necessary for the fluorination.7a

9

Even at 75 ˚C, the difluorinated product of methyl adaman-tane-1-carboxylate or 1-(acetoxymethyl)adamantane was not obtained.
