Vanadium(V) oxytrifluoride is a chemical compound with the formula V O F₃. It is one of several vanadium(V) oxyhalides. VOF₃ is a yellowish orange powder that is sensitive to moisture.[1] Characteristic of early metal fluorides, the structure is polymeric in the solid state. The solid adopts a layered structure but upon evaporation, the species becomes dimeric. In contrast VOCl₃ and VOBr₃ remain tetrahedral in all states, being volatile liquids at room temperature.[2]

In organic synthesis, VOF₃ is often used for the oxidative coupling of phenolic rings, for example in the syntheses of vancomycin and its analogues.[3] For these applications VOF₃ is typically dissolved in trifluoroacetic acid.
