Reactivity of B(C6F5)3 with oxovanadium(v) complexes VOL3 (L = OCH2CF3, NEt2): Formation of the organometallic vanadium(v) complex [VO(μ-OCH2CF3)(OCH2CF3) (C6F5)]2 and the Lewis acid adduct

Treatment of the oxovanadium(v) complex [VO(OCH2CF3)3]2 (3) with the Lewis acid B(C6F5)3 leads to aryl/alkoxy group exchange and formation of the unexpected organometallic oxovanadium(v) [VO(μ-OCH2CF3)(OCH2CF3) (C6F5)]2 (1), while reaction of B(C6F5)3 and [VO(NEt2)3] produces the Lewis acid adduct [(Et2N)3VO·B(C6F5) 3] (2). The crystal structures of 1, 2 and 3 were determined, 51V NMR chemical shifts for complexes 1-3 and [VO(NEt2)3] are discussed. A concentration-dependant monomer-dimer equilibrium for 3 is observed in solution. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
