Abstract: | A New Contribution to the Phosphazo Reaction The reaction of acrylonitrile with phosphorus pentachloride gives ClCH2CCl2CCl2NPCl3 (I) and a hexachlorophosphate with the composition C3H2Cl14NP3 (II). For the first time the structure of (II) has been exactly determined by using 1H- and 31P-NMR-spectra. The course of reaction was studied in detail. 3-chloropropionitrile has been found as the product of a secondary reaction. The reaction of butyramide with PCl5 has also been investigated, and was found to be analogous. |
