A Novel Three-Component Reaction of Triphenylphosphine, DMAD, and Electron-Deficient Styrenes: Facile Synthesis of Cyclopentenyl Phosphoranes

Abstract

The zwitterion formed from triphenylphosphine and DMAD adds to electron-deficient styrenes to form stable cyclopentenyl phosphoranes. This is the first example of such a zwitterion in which the phosphine is incorporated into the product

Key words

triphenylphosphine - dimethyl acetylenedicarboxylate - zwitterions - electron-deficient styrenes - phosphoranes
