In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Copper/α-Ketocarboxylate Chemistry With Supporting Peralkylated Diamines: Reactivity of Copper(I) Complexes and Dicopper-Oxygen Intermediates, published in 2010-04-05, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, Electric Literature of C9H11Cu.
To further understand Cu-promoted oxidation reactions, the Cu(I) complexes LCuX (L = N,N’-di-tert-butyl-N,N’-dimethylethylenediamine; X = benzoylformate (BF) or p-nitro-benzoylformate) were synthesized, fully characterized by x-ray crystallog. and spectroscopy in solution, and their reactivity with O2 at -80° examined Oxidative decarboxylation of the α-ketocarboxylate ligand was observed, but only to a significant extent when cyclohexene, cyclooctene, or MeCN was present. Spectroscopic and conductivity data are consistent with mechanistic postulates involving displacement of the α-ketocarboxylate by the additives to a small extent, followed by oxygenation of the LCu(I) moiety to yield Cu-O species that subsequently induce decarboxylation. To test these hypotheses, spectroscopic and kinetic studies of the reactions of Bu4NBF with preformed μ-η2:η2-peroxodicopper(II) and/or bis(μ-oxo)dicopper(III) complexes supported by L or N,N,N’,N’-tetramethylpropylenediamine were performed. In an illustration of a new mode of reactivity for such dicopper-O cores, decarboxylation of the added α-ketocarboxylate was observed and the intermediacy of a carboxylate-bridged μ-η2:η2-peroxodicopper(II) complex was implicated.
