Vanadium(V) oxytrifluoride is a chemical compound with the formula VOF3.
[2] 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.
[3] In organic synthesis, VOF3 is used for the oxidative coupling of phenols, for example in the syntheses of vancomycin and its analogues.
