The high chemical passivity of the so-called "inert free radicals" (IFRs), particularly those derived from perchlorotriphenylmethyl (PTM), has allowed one to ascertain the kinetic influence of the free radical character on the reactivity of their nonradic

The free radical character of the benzyl bromide (1) causes accelerations in the nucleophilic substitution reactions with acetate and with diethyl malonate anions which are interpreted in terms of a change-transfer, biradical configuration for the SN2 transition state.
