1H and 2H NMR spectroscopic characterization of the V(III) ion-pair intermediates formed upon the activation of α-diimine vanadium(III) chloride L3,5−MeVIIICl3(THF) (L3,5−Me = 1,4-bis-3,5-dimethylphenyl-2,3-dimethyl-1,4-diazabuta-1,3-diene) with AlMe3/[Ph3C][B(C6F5)]4 and MAO is reported. In contrast to previously reported heterobinuclear ion pairs of the type [L1(R)VIII(μ-R)2AlMe2]+[A]− (L1 = bis(imino)pyridine ligand, [A]− = [B(C6F5)4]− or [MeMAO]−, R = Me or Cl), species of the type [L3,5−MeVMe2(THF)2]+[B(C6F5)4]−, [L3,5−MeVMe2(THF)2]+[MeMAO]− and [L3,5−MeVMe2+⟵MeMAO−] were identified.
