Abstract

-The N-substituents are transferred from the title cations to the C-atom of nitroalkane anions in high yield at 25-80° C in DMSO solution. The title cations are readily available from the appropriate pyrylium cations and primary amines of types RCH2, NH2, and RR'CHNH2, allowing a general 2-step method for the preparation of higher nitro-alkanes. Spectral properties of a variety of nitroalkanes are discussed.
