Elemental fluorine substitutes tertiary unactivated hydrogens in an electrophilic mode. This unorthodox substitution depends on the atomic charge density, on the hydrogen atom and on the p-orbital contribution on the CH bond. This is demonstrated by reacting F2 with tertiary CH bonds located on rings of various sizes, producing the corresponding tertiary fluorine derivatives.
