- The N-substituents are transferred from the title cations to the C-atom of nitroalkane anions in highyield 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

alk-l-ynyltrimethylstannane results in the rapid formation of trimethylstannyl acetate and an unstable species, believed to be the corresponding alk-l-ynyllead triacetate, which can effect the rapid α-alkynylation of β-dicarbonylcompounds and nitronatesalts.
