Organovanadium chemistry

Organovanadium chemistry is the chemistry of organometallic compounds containing a carbon to vanadium (V) chemical bond. Organovanadium compounds are of some relevance to organic synthesis and to polymer chemistry as reagents and catalysts.

Oxidation states for vanadium are +2, +3, +4 and +5. Low valency vanadium is usually stabilized with carbonyl ligands. Oxo ligands for example in vanadyl ions are common when the valency increases. In most compounds outside the oxidation state of +5, vanadium is paramagnetic hampering NMR spectroscopy. Typical vanadium precursors are vanadium(III) chloride and its adduct with THF VCl₃(THF)₃ and vanadium tetrachloride.
