Radical reduction of alkyl and aryl halides is a fundamental and important reaction in organic synthesis, and has been extensively used. Although inorganic chemists have been aware of free radicals for many years it is only recently that their importance in biochemistry and medicine has become more widely appreciated. The toxic nature of free radicals was firmly brought to the attention of the public by the recent. The book covers a wide range of free radicals and it is certain that, with the continuing research in this field, the crucial role of these chemical species in normal and pathological biochemical processes will become increasingly apparent. Consequently, the book provides essential guidance to the practical aspects of free radical chain reactions for students, chemists, and practitioners.
