The preparation of a new inorganic ring system containing one sulfur, two phosphorus and three nitrogen atoms in the ring

Abstract

The results of the thermal decomposition at low pressure of Cl3P  NPCl2 ; NSO2Cl, Cl3P  NPCl2  NPCl2  NSO2Cl and mixtures of these compounds with Cl3P  NSO2Cl, are reported. In all cases inorganic heterocycli, containing nitrogen phosphorus and/or sulfur atoms, were obtained. The isolation of the hitherto unknown compound (NPCl2)2 NSOCl is described. A short discussion of the I.R. spectra of α‐(NSOCl)3, NPCl2(NSOCl)2, (NPCl2)2 NSOCl and (NPCl2)3 is given.
