资源简介：
Cations derived from (NPCl2)3, hexachloro-cyclo-triphosphazene,
the weakly basic precursor of phosphazene polymers, have been
prepared using strongly electrophilic reagents based on carborane
anions. N-protonated, N-methylated, and N-silylated adducts of
(NPCl2)3 have been isolated and characterized by X-ray crystallographic and spectroscopic methods. The normally potent chloride-abstracting silyl reagents of the type R3Si(carborane) are unable
to abstract chloride from (NPCl2)3, even though the coordinatively
unsaturated N2P2Cl5+ cation is widely accepted as a reactive
intermediate in the ring-opening polymerization of (NPCl2)3.
