At least three different cationic species arise in the classic protonolysis of [V IV (NEt 2 ) 4 ] with a borate ammonium salt. The unexpected formation of the vanadium( V ) species [V(NEt 2 ) 4 ][B(C 6 H 5 ) 4 ] (shown in the picture without its counterion) underlines the problem of deducing the true oxidation state of vanadium species in Ziegler–Natta reactions.
