Abstract The distribution of products of benzhydryl bromide heterolysis in the presence of triphenylverdazyl in anhydrous nitrobenzene and propylene carbonate, as well as in anhydrous acetonitrile in the presence of benzyltriethylammonium chloride was studied. In kinetic experiments the contribution of verdazyl alkylation was always minor, and verdazyl was mostly consumed in the reaction with HBr evolved during solvolysis. Thus, ...
