Article abstract of DOI:10.1016/0040-4020(95)00353-A

The synthesis of new organic free radicals of the PTM (perchlorotriphenylmethyl) series with different substituents in the 3- and 5-positions of one phenyl ring and their α-H precursors are described.All these radicals are stable red solids with high melting points.Their electron spin resonance spectra in solution and their magnetic susceptibilities in solid are reported and commented upon.Electrochemical behavior of radical 5 by means of cyclic voltammetry is also presented.
