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.
元素氟以亲电模式取代未活化的叔氢。这种非常规的取代取决于原子电荷密度,氢原子以及对CH键的p轨道贡献。通过使F 2与位于各种尺寸的环上的叔CH键反应,生成相应的叔氟衍生物,可以证明这一点。
