Energy, activation from inorganic compounds

The reactions of elemental fluorine with inorganic compounds are exothermic and often have little or no reaction associated activation energies. Most often the major synthetic problem is kinetic and thermodynamic control of these vigorous reactions. It is therefore a very unusual synthetic situation when reactions must be activated by methods such as high temperatures, plasmas, or photochemical means. Examples of such cases are the synthesis of NO+BF4 by the photochemically activated reaction of fluorine and oxygen with boronnitride (52) and the plasma-activated synthesis of (CF112)n from graphite (53).
