The interaction of Ph3Ti with a number of ketones (acetone, 2-butanone, 3,3-dimethyl-2-butanone, benzophenone) was studied.The PhTi(OCR1R2Ph)2 complexes, where R1=R2=Me (a), R1=Me, R2=Et (b), R1=Me, R2=t-Bu (c), and R1=R2=Ph (d) were isolated in satisfactory yields.These compounds were characterized by ESR and IR spectroscopy and elemental analysis.Their thermal stability was determined by the DTA method.The reaction of Bn3V with acetone gives V(OCMe2Bn)3.In analogy with titanium compounds, BN4V reacts with acetone at the ratio 1 : 2 to give Bn2(OCMe2Bn)2. - ke words: ketones; phenyltitanium dialkoxides; dibenzylvanadium dialkoxide, vanadium trialkoxide.

Reactions of VCl3*3THF with RMgX (R = Ph, CH2SiMe3, C6F5) in various ratios have been studied.The stable compounds R3V*THF (R = CH2SiMe3, C6F5) were obtained.The chemical properties of R3V*THF, R4V*2L (R = CH2Ph, L = Et2O; R = C6F5, L = THF) and (Me3SiCH2)4V were investigated.Cleavage of the vanadium-carbonium ?-bond occurs in reactions with H2O, HCl and HgCl2.The insertion of carbon dioxide into the vanadium-carbon ?-bond was investigated.A scheme for the derivatives of tri- and tetravalent vanadium is proposed.Oxidative addition to (C6F5)3V*THF by Ph3CCl and VCl3*3THF was also studied.
