Derivatives of NPCl2(NSOCl)2 and (NPCl2)2NSOCl, Part XXIII [1]. Reactivity in Aminolysis Reactions by NH3

Abstract

Reactions of the cyclic systems (NPCl2)2NSOX and NPCl2(NSOX)2 (X = F, Cl, Ph) with NH3 in diethyl ether or acetonitrile at low temperature provide convincing evidence that the P-bonded chlorine atoms are replaced by NH2 groups along a geminal pathway. No disruption of the S-F and S-Ph bonds occurs. Aminolysis of NPCl2(NSOCl)2 proceeds to NP(NH2)2(NSOCl)2, followed by decomposition, (NPCl2)2NSOCl can be transformed to NPClNH2NP(NH2)2NSOCl without cleavage of the ring skeleton
