Vanadium(V) oxytrifluoride is a chemical compound with the formula VOF3. 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.
