Approaches to stable cyclopropenyl anions: tris-1,2,3-p-Nitrophenylcyclopropene

Article abstract of DOI:10.1016/S0040-4020(97)00129-4

Tris-1,2,3-p-nitrophenylcyclopropene has been synthesized from the tosylhydrazone of an enone, and examined as a precursor of the corresponding cyclopropenyl anion. A precursor of the related trimethylsilylcyclopropene has also been prepared by a series of palladium-catalyzed reactions.
