PRECIS DE LA DIVULGATION: Des phosphinamides sont préparés par l'action d'un halogénure organique sur une oxazaphospholidine. Selon la configuration, désirée pour le stéréoisomère à obtenir, on utilise une oxazaphospholidine issue d'un aminoalcool optiquement actif (+) ou (-). Ces phosphinamides sont utiles à la préparation de phosphinates, en particulier de phosphi- nates optiquement actifs, de configuration absolue, connue; pour cela le phosphinamide est soumis à l'alcoolyse.
