Vanadyl isopropoxide is the metal alkoxide with the formula VO(O-iPr)₃ (iPr = CH(CH₃)₂). A yellow volatile liquid, it is a common alkoxide of vanadium. It is used as a reagent and as a precursor to vanadium oxides.^[1] The compound is diamagnetic. It is prepared by alcoholysis of vanadyl trichloride:

VOCl₃ + 3 HOCH(CH₃)₂ → VO(OCH(CH₃)₂)₃ + 3 HCl

The related cyclopentanoxide VO(O-CH(CH₂)₄)₃ is a dimer, one pair of alkoxide ligands bind weakly trans to the vanadyl oxygens.^[2]
