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
