Darstellung von Carbonsaeure-dihalogenphosphorsaeure-anhydriden

The mixed anhydrides 3, 4, 6, and 7 are prepared in good yields by conproportionation of the respective carboxylic and dihalophosphoric anhydrides 1 and 2.The aryl derivatives 3 and 4 can be isolated in neat form, the alkyl compounds 6 and 7 undergo further reactions upon destillation.For the combination of trihaloacetic and dihalophosphoric anhydrides, the equilibrium is shifted to the side of the symmetrical anhydrides (5d, e and 2).
