Abstract: The interaction of vanadium compounds (VCl(4) and VOCl(3)) with alcohols (tert-butanol and 2-ethyl-1-hexanol) and aluminum alkoxides Al(OR)(2)Cl is studied by EPR, (51)V NMR, and electronic absorption spectroscopy. (51)V NMR evidence shows that the reaction of VOCl(3) with alcohols results in a successive substitution of alkoxy groups for the chlorine atoms in vanadium oxytrichloride. In this process, the amount of alcohol required for obtaining di- and trisubstituted alkoxo derivatives exceeds the stoichiometric amounts. Synthesis of alkoxy derivatives of VOCl(3) is shown to be accompanied by a side reaction of the reduction of vanadium to V(4+). It is found that the reaction of VOCl(3) with Al(OR)(2)Cl leads to the formation of monoalkoxide derivatives of vanadium oxytrichloride. Upon interaction of VCl(4) with alcohols (tert-butanol and 2-ethyl-1-hexanol) or aluminum alkoxides, only two chlorine atoms are replaced by alkoxy groups to form vanadium alkoxide of the composition V(OR)(2)Cl(2) center dot ROH.
