Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Colloidal Cu/ZnO catalysts for the hydrogenation of carbon dioxide to methanol: investigating catalyst preparation and ligand effects. Author is Pike, Sebastian D.; Garcia-Trenco, Andres; White, Edward R.; Leung, Alice H. M.; Weiner, Jonathan; Shaffer, Milo S. P.; Williams, Charlotte K..

The production of methanol from CO2 hydrogenation is a promising potential route to a renewable liquid fuel and renewable energy vector. Herein, three distinct routes to make colloidal catalysts based on mixtures of Cu(0) and ZnO nanoparticles (NPs) and using low-temperature organometallic procedures are reported. The colloids are surface coordinated by a phosphinate ligand: dioctylphosphinate ([DOPA]-), which delivers a high solubility in organic solvents. Further, the synthetic routes allow fine control of the ZnO:Cu and ligand loadings. The catalysts are prepared by mixing small NPs (2 nm) of either Cu(0) or air-stable Cu2O NPs with ZnO NPs (3 nm), or by the synthesis of Cu(0) in presence of ZnO NPs (ZnO: 2 nm, Cu: 6 nm). The resulting colloidal catalysts are applied in the liquid phase hydrogenation of CO2 to methanol (210°, 50 bar, 3 : 1 molar ratio of CO2 : H2). The catalysts typically exhibit 3 times higher rates when compared to a heterogeneous Cu-ZnO-Al2O3 com. catalyst (21 vs. 7 mmolMeOH gCuZnO-1 h-1). The characterization of the post-catalysis colloids show clear Cu/ZnO interfaces (HR-TEM), which are formed under reducing conditions, as well as differences in the Cu(0) NP size (from 3 to 7 nm) and nanoscale restructuring of the catalysts. The combination of characterization and catalytic results indicate that the activity is mostly dictated by the Cu(0) particle size and ligand loading. Smaller Cu(0) NPs exhibited lower turnover frequency (TOF) values, whereas higher ligand loadings ([DOPA]-:(Cu + Zn) of 0.2-1.1) lead to smaller Cu(0) NPs and reduce the formation of Cu/ZnO interfaces. UV-vis spectroscopy reveals that the Cu(0) NPs are more stable to oxidation under air after catalysis than beforehand, potentially due to migration of ZnO onto the Cu surface while under catalytic conditions.

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.
