Synthetically Reversible, Proton-Mediated Nitrite N-O Bond Cleavage at a Dicopper Site.

ABSTRACT: A monocationic dicopper(I,I) nitrite complex [Cu₂(μ-κ¹:κ¹-O₂N)DPFN][NTf₂] (2) (DPFN = 2,7-bis(fluoro-di(2-pyridyl)methyl)-1,8-naphthyridine, NTf₂^- = N(SO₂CF₃)₂^-), was synthesized by treatment of a dicopper acetonitrile complex, [Cu₂(μ-MeCN)DPFN][NTf₂]₂ (1), with tetrabutylammonium nitrite ([nBu₄N][NO₂]). DFT calculations indicate that 2 is one of three linkage isomers that are close in energy and presumably accessible in solution. Reaction of the μ-κ¹:κ¹-O₂N complex with p-TolSH produces nitrous acid (HONO) and the corresponding dicopper thiolate spe
