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]
