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
