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