Phosphazene, XLIV Unsymmetrisch Organosubstituierte Diphosphornitrid-Verbindungen

Abstract

Diphosphornitride cations which bear chlorine substituents at both phosphorus atoms are obtained by the action of chlorophosphoranes RPC1₄ or R₂PC1₃ on phosphinic thioamides R₂PSNH₂. The two components can contain different R groups to produce unsymmetric species. The chlorine can subsequently be exchanged by reaction with NH₃, SO₂ or HCOOH. ³¹P- and ¹H-NMR-data elucidate the structures.
