Carbon-halogen bond formation fluorine

Halogenated hydrocarbons undergo an insertion reaction in the carbon-halogen bond and, in the case of fluorine, the reaction products are explosive, probably because of the large energy of formation of the Si—F bond. 

Considerably less work has been done on the kinetic aspects of the radiolysis of fluorine compounds than on other halogen compounds. With °Co y-radiation, perfluoromethane produces perfluoroethane , and perfluoroethane produces (refs. 351, 352) a mixture of perfluoromethane, -propane, -butane, -cyclopropane, and -acetylene. Similar radiolysis studies on perfluorocyclobutane , perfluoro-cyclohexane and other perfluoro-compounds show that the dominant process is one of rupture of the carbon-carbon bond with the formation of a variety of perfluoro-compounds as products.
