Abstract

The cationic N-species [(-HCF)PN] () featuring a perfluoro-arene phosphonium group serves as a N-source in stoichiometric reactions with several Lewis bases (L) allowing for the stepwise formation of [(L)N] and [(L)N] cations (L = phosphine, carbene) with liberation of (-HCF)P. X-Ray diffraction analysis and computational studies provide insight into the bonding in these remarkably stable azido-cations.

摘要

具有全氟芳烃鏻基团的阳离子型氮物种[(-HCF)PN]（）在与几种路易斯碱（L）的化学计量反应中作为氮源，能够逐步形成[(L)N]和[(L)N]阳离子（L = 膦、卡宾），同时释放出(-HCF)P。X射线衍射分析和计算研究揭示了这些极其稳定的叠氮阳离子中的键合情况。
