Abstract
Singly, doubly and triply bridged polyazaheterophanes (1,2,3) have been synthesized from hexachlorocyclotriphosphazene, N3P3Cl6. 31P NMR spectra indicate that the molecules 2 exist in a single conformation when there are three differently populated conformations A, B and C, in molecules 3 at ambient temperature, A and (B + C) being separated by a high interconversion barrier (about 22 Kcal mole−1) whereas the barrier between B and C is much lower (about 4 Kcal mol−1).Keywords
