  Late-Metal Nitrosyl Cations: Synthesis and Reactivity of [Ni(NO)(MeNO₂)₃][PF₆]

  摘要：

  The reaction of [NO][PF6] with excess Ni powder in CH3NO2, in the presence of 2 mol % NiI2, results in the formation of [Ni(NO)(CH3NO2)(3)][PF6] (1), which can be isolated in modest yield as a blue crystalline solid. Also formed in the reaction is [Ni(CH3NO2)(6)][PF6](2) (2), which can be isolated in comparable yield as a pale-green solid. In the solid state, 1 exhibits tetrahedral geometry about the Ni center with a linear nitrosyl ligand [Ni1-N1-O1 = 174.1(8)degrees] and a short Ni-N bond distance [1.626(6) angstrom]. As anticipated, the weakly coordinating nitromethane ligands in 1 are easily displaced by a variety of donors, including Et2O, MeCN, and piperidine (NC5H11). More surprisingly, the addition of mesitylene to 1 results in the formation of an eta(6)-coordinated nickel arene complex, [Ni(eta(6)-1,3,5-Me3C6H3)(NO)][PF6] (6). In the solid state, complex 6 exhibits a long Ni-C-cent distance [1.682(2) angstrom], suggesting a relatively weak Ni-arene interaction, a consequence of the strong pi-back-donation to the nitrosyl ligand. The addition of anisole to 1 also results in the formation of a eta(6) nickel arene complex, [Ni(eta(6)-MeOC6H5)(NO)][PF6] (7). This complex also exhibits a long Ni-C-cent distance [1.684(1) angstrom].

  results in formation of the hyponitrite complex, [(bipy)Ni(κ2-O2N2)}η1:η1-N,N-Ni(NO)(bipy)}2][PF6]2 (9), in modest yield. Importantly, the hyponitrite ligand in 9 is thought to form via coupling of two NO– ligands and not by coupling of a nucleophilic nitrosyl ligand (NO–) with an electrophilic nitrosyl ligand (NO+). X-ray crystallography reveals that complex 9 features a new binding mode of the cis-hyponitrite
