Perchlorofluoroalkanes such as Freon-113 are renowned for their chemical stabilityand thus are fiequently used in laboratory as inert solvents even for radical reactions.Withthe exception of their reactions with metals and Lewis acids,very few other reactions havebeen investigated.The carbon atoms of these perhalohydrocarbons are not vulnerable todirect S_N2 type attacks by nucleophiles,thus the latter can only set on the exposed halogenatoms.In fact,examples of bromophilic attacks of this type have been reported,but no
