Reactions of free radicals. Free radicals can be defined as molecules or molecular fragments containing one or more unpaired electrons.11 Although this definition does not specify exactly, where the unpaired electron is present, still it is preferred because it allows us to classify most of the transition metal ions as free radicals and thus better understand the close interrelation between
