Regiospecific uncatalyzed hydrophosphination of compounds possessing mutiple bonds leads to the formation in good yields of various polyfunctionalyzed systems. A good stereoselectivity is observed when a chiral electrophile is used. The mild conditions observed in all these reactions are a consequence of the strong PH activation induced by the unsaturated fragments directly bonded to the phosphorus atom
