Abstract

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)

B(C6F5)3与氧化钒(V)配合物VOL3 (L = OCH2CF3, NEt2)的反应性:有机金属钒(V)配合物[VO(μ-OCH2CF3)(OCH2CF3)(C6F5)]2和Lewis酸加合物[(Et2N)3VO·B(C6F5)3]的形成

氧化钒(V)配合物[VO(OCH2CF3)3]2(3)与Lewis酸B(C6F5)3处理后，发生芳基/烷氧基交换，生成意料外的有机金属氧化钒(V) [VO(μ-OCH2CF3)(OCH2CF3)(C6F5)]2(1)，而B(C6F5)3与[VO(NEt2)3]反应生成Lewis酸加合物[(Et2N)3VO·B(C6F5)3](2)。讨论了配合物1−3和[VO(NEt2)3]的51V核磁共振化学位移。在溶液中观察到浓度依赖的单体-二聚体平衡。(©Wiley-VCH Verlag GmbH &KGaA公司，德国Weinheim, 69451, 2003)
