Compared with 2,4,6-triphenylpyridine, 2,6-diphenyl-4-(o-substituted phenyl)pyridines as leaving groups in the radicaloid nucleophilic displacement reaction with 2-nitropropanide anion slow down C.T.C. formation. o-Substitution of the 2-phenyl group has little effect on this reaction.The latter modification however decreases SN2 rates of the corresponding pyridiniums with piperidine.
