2. General information on fluorination processes

Unlike chlorine derivatives, which are essentially obtained by chlorination reactions with chlorine (substitution of a hydrogen atom or addition to a compound with a double or triple bond $\text{CCC}$ ), fluorine derivatives can only exceptionally be manufactured from elemental fluorine.

Due to the very high bond energies $\text{CCF}$ (447 to 505 kJ/mol) and HF (566 kJ/mol), fluorinations with elemental fluorine, such as : .
