Composés du phosphore dicoordonné: action des amines sur les triazaphospholes-1,2,4,3 substitués en 2,5. Étude thermodynamique de l'équilibre de formation des triazaphospholines et caractérisation de leurs dérivés tétracoordonnés

The oxidation of 2,5-disubstituted 1,2,4,3-triazaphospholes with amines gives 1,2 addition products by an equilibrium reaction. This equilibrium has been proved by temperature lowering and also by chemical reaction: addition of sulfur, selenium, or azide (X) shifts the equilibrium to the 1,2 addition products:[Formula: see text]The thermodynamical parameters associated with this equilibrium have been determinated in some cases.
