ResumoAminolysis of the genuine monoANSA derivative, N3P3Cl4[HN(CH2)2O(CH2)2NH], 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.
