Abstract

From the reaction of N3P3Cl6 with 1,3-dihydroxypropane two isomeric N3P3Cl2[O(CH2)3]2 derivatives were isolated, whose NMR spectra suggest, and crystal structures prove, them to represent an example of dispiro / spiro-ansa isomerism, the first of its kind in phosphazene chemistry. The crystal structures and NMR spectra are discussed. Extension of the work with difunctional reagents is reported.
