✦ Synopsis

Sincecyclicvottammetry is a useful method to evaluate the electron-donor and -acceptor properties of organic and inorganic compounds, it is ofconsiderable interest to study free radicals by this electrochemicat technique. However, the free radicals which can be studied by this technique are significantly limited owing to their wellknown transient properties[l J. This problem has been overcome in part by the use of a special technique [2].

In this paper we report the cyclic voltammetric behaviour of N-[(4-nitrophenyl)thioJ-2,4,6-tri-tertbutylphenylaminyl radical (I), which is interesting as a new class of isolable nitrogen-centred free radicals[3]. NHS NO2 2 EXPERIMENTAL N-[(4-Nitrophenyl)-2,4,6-tri-tert-butylphenylaminyl radical (1) and N-[ (6nitrophenyl)thioJ-2,4,dtri-tertbutylaniline (2) were prepared by our previously reported method[3].
