Abstract
New formazans, tetrazines, and verdazyl radicals containing pentafluorophenyl residues were synthesized on the basis of the reaction of perfluorophenylhydrazones with benzenediazonium salts. The stabilities of the free radicals obtained considerably exceed the stability of the diphenylpicrylhydrazyl radical.
