摘要：

The cationic vanadocene alkyl complex [Cp2VMe(CH3CN)](+) with [BPh4](-) counteranion was structurally established. The reaction of Cp2VMe2 in THF in the presence of B(C6F5)(3) is also described: EPR evidence of the intermediate formation of the [Cp2VMe(THF)](+) species, which gives, via a disproportionation redox reaction, the V-III species [Cp2V(THF)][Me B(C6F5)(3)], is demonstrated.
