  Formation of N₂O from a Nickel Nitrosyl: Isolation of the cis-[N₂O₂]^2– Intermediate

  摘要：

  Addition of 2,2'-bipyridine (bipy) to [Ni(NO)(bipy)][PF6] (1) results in formation of a rare five-coordinate nickel nitrosyl [Ni(NO)(bipy)(2)][PF6] (2). This complex exhibits a bent NO- ligand in the solid state. On standing in acetonitrile, 2 furnishes the NO coupled product, [Ni(kappa(2)-O2N2)(bipy)] (8) in moderate yield. Subsequent addition of 2 equiv of acetylacetone (H(acac)) to 8 results in formation of [Ni(acac)(2)(bipy)], N2O, and H2O. Preliminary mechanistic studies suggest that the N-N bond is formed via a bimetallic coupling reaction of two NO- ligands.

  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
