The beta -diketone complexes of vanadium(IV), VO(dik)//2 (where dik EQUVLNT btfac, tfac, ttfac, acac, bzac and bzbz) have been prepared either by the reaction of vanadium pentoxide with the appropriate ligand in toluene under reflux for 24 h or by the reaction of a warm aqueous or ethanolic solution of vanadium sulphate with the ligand. The oxovanadium(IV) complexes react with sulphur oxide dichloride and dibromide and phosphorus pentachloride to form dihalovanadium(IV) diketonate complexes. These compounds have been characterized by elemental analysis, melting point measurements, IR and Raman spectra, magnetic susceptibility measurements, electron spin resonance (ESR) and mass spectral studies and X-ray powder diffraction.
Molecular vapor synthesis: The use of titanium monoxide and vanadium monoxide vapors as reagents

The production and reactivity of titanium monoxide (TiO) and vanadium monoxide (VO) on a synthetically useful scale were studied by using the techniques and apparatus previously developed for reactions of metal atoms. Cocondensation reactions with chlorine showed that greater amounts of metal atoms were produced as impurities in the vapor when stoichiometric metal monoxides were used as vapor sources than when metal sesquioxides were used. It was found that evaporation of MO and M2O3 solids from open tungsten boats yielded vapor compositions of M, MO, and MO2 similar to those reported earlier from Knudsen cells in the case of vanadium but somewhat different in the case of titanium. The monoxide molecules reacted with chlorine to produce oxometal chlorides in high yields. They reacted with 2,4-pentanedione and other organics containing relatively acidic hydrogen, to form water as a byproduct via protonation of the oxo moiety; coordination compounds of titanium and vanadium were isolated as acac complexes in high yields.
