In pursuit of the PO2+ cation. The reaction of KPO2F2 and SbF5 leads to an eight-membered antimony-oxygen-phosphorus-bridged ring

摘要

The reaction of KPO2F2 with the strong Lewis acid SbF5 was studied as a potential pathway to the unknown PO2+ cation. The resulting product has the desired PO2SbF6 composition but consists of an eight-membered, antimony-oxygen-phosphorus-bridged ring that was characterized by vibrational and NMR spectroscopy, ab initio methods, and a Institute. University of Southern California. University Park single crystal x-ray diffraction study. The preferred formation of the ring and its mechanism are discussed. [References: 25]
