POLYNITRO ALIPHATIC SYNTHESIS.

Abstract

Carbomethoxymethylene triphenylphosphorane and conjugated nitroolefins react with subsequent proton-transfer to give phosphorus ylides, carbomethoxynitro alkylidene triphenylphosphoranes (I). The structures of I were established from their infrared and ultraviolet absorptions. Chemical evidence for the structure of a typical phosphorane was obtained by its bromination and subsequent regeneration by aqueous sodium carbonate. Methylene triphenylphosphorane and dimethylsulfoxonium methylide (II) react with conjugated nitroolefins to yield nitrocyclopropanes; II is the much more efficient and convenient reagent. The spectral properties of various nitrocyclopropanes are described. (Author)
