Beschreibung

Allgemeine Beschreibung

Reaction of phosphorus pentabromide with phosphorus pentoxide at elevated temperatures affords phosphorus(V) oxybromide. Its Raman spectrum has been studied and the molecule has been reported to exhibit point group symmetry C_3v.[1] Phosphorus(V) oxybromide (Phosphorus oxide bromide) participates in the preparation of 1:1 addition ionic compound having melting point at 154·0°C, via reaction with gallium tribromide. This ionic compound contains non-metal cation POBr₂⁺.[2]

Anwendung

Phosphorus(V) oxybromide may be used as brominating reagent in the synthesis of 2,4,6-tribromopyrimidine.[3] It may be used in the preparation of bromoheterocyclic compounds.[4]
