The article present the studies made on several aliphatic nitro derivatives. The studies were made in acetonitrile. For all the investigated compounds we observed the cleavage in cyclopropyl radical and nitrite ion in an aprotic medium. Cyclic voltammograms and preparative electrolyses (performed under potentiostatic conditions in an H cell on a glassy carbon in dry acetonitrile containing Bu4NPF6, c = 0.1 M, as supporting electrolyte) of nitrocumene and of some nitrocyclopropanes will be presented and discussed in the light of the different mechanistic pathways of cleavage of the radical anions.
