The N-substituents are transferred from the title cations to the C-atom of nitroalkane anions in high yield at 25-80 deg C in DMSO solution.The title cations are readily available from the appropriate pyrylium cations and primary amines of types RCH2NH2 and RR'CHNH2, allowing a general 2-step method for the preparation of higher nitroalkanes.Spectral properties of a variety of nitroalkanes are discussed.
2- and 4-(α-Substituted Aryl)pyridines as Leaving Groups in SN2 Reactions and Radicaloid Nucleophilic Displacements.

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.
