  • Readily undergoes additions with nucleophiles, e.g. alcohols or amines, to give 2-alkoxy or 2-alkylamino propenyl phosphonium salts. In these reactions, the reactive species is the allenic isomer, propadienyl triphenylphosphonium bromide: J. Org. Chem., 42, 200 (1977). By using a chiral alcohol, the subsequent base-promoted Wittig reaction with carbonyl compounds yields amino or alkoxy dienes which undergo face-selective Diels-Alder additions to dienophiles: J. Chem. Soc., Chem. Commun., 1785 (1995):
