Abstract: The invention comprises cyclopentadienyl vanadium oxydihalides of formula (C5H5) VOX2 where X is halogen. They may be prepared by reacting cyclopentadienyl vanadium carbonyl compound such as cyclopentadienyl vanadium tetracarbonyl in the absence of water with a hydrogen halide or a compound which splits off hydrogen halide, and an oxidising agent. Suitable oxidising agents include chlorine, bromine and iodine, compounds which readily split off halogen such as lead tetrachloride, oxygen, gas mixtures containing oxygen or compounds which evolve oxygen. The reaction may be carried out in proton-inactive solvents such as benzene and its homologues, chlorinated hydrocarbons such as chloroform and carbon tetrachloride, ketones, aldehydes and ethers. The preparation of cyclopentadienyl vanadium oxydichloride and cyclopentadienyl vanadium oxydibromide is described.
