An answer to the spiro versus ansa dilemma in cyclophosphazenes: Part X. The serendipitous chemistry of the genuine cyclophosphazenic monoANSA derivative N 3P 3Cl 4[HNCH 2) 2OCH 2) 2NH

Abstract

Aminolysis of the genuine monoANSA derivative, N 3P 3Cl 4[HN(CH 2) 2O(CH 2) 2NH], leads to neat new B.A.S.I.C. structures in which the chlorine atoms trans to the ANSA arch are never involved. This is the first time to our knowledge that non-reactive chlorine atoms of a phosphonitrilic chloride trimer are made conspicuous.
