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 Oligonuclear Homoleptic Copper(I) Pyrazolates with Multinucleating Ligand Scaffolds: High Structural Diversity in Solid-State and Solution, published in 2009-11-02, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, Synthetic Route of C9H11Cu.

The synthesis of three pyrazole-based, potentially binucleating ligands 3,5-bis(R1NMeCH2)-4-R2pyrazole (L1H: R1 = pyridyl-2-methyl-, R2 = Ph; L2H: R1 = 8-quinolyl-, R2 = H; L3H: R1 = 8-quinolyl-, R2 = Ph) is described. Reaction of L1-3H with 1 equiv of mesitylcopper affords oligonuclear homoleptic complexes [CuL]n (1-3). The single crystal x-ray structure of 2 shows a tetranuclear assembly of linear coordinated Cu(I)-centers bridged by pyrazolato ligands that alternate above and below the Cu4 plane, with addnl. weak interactions from some of the ligand side arms. As the single crystal X-ray structure of 3 reveals, Ph substitution at the 4-position of the pyrazolato framework leads to significant structural modification of the Cu4 array, giving a rhombical tetranuclear complex with two linear coordinated Cu(I) centers that exhibit a short intramol. Cu···Cu contact (2.8212(10) Å) and two peripheral Cu(I) centers in a distorted tetrahedral coordination mode. Thus, 3 represents a very rare example of an inorganic pyrazolato cuprate which can also be viewed as a partly rearranged structural isomer of 2. Also, the crystal lattice of 3 shows an extended network of intra- and intermol. π-π stacking interactions between the aromatic rings. In solution, 1-3 each form two types of oligomers a and b that slowly (<1 s-1) equilibrate at room temperature Using Diffusion Ordered Spectroscopy (DOSY) and variable temperature 1H NMR spectroscopy, a and b correspond to a tetrameric and a (planar) trimeric species. Coordination of the pyridyl/quinolyl side arms that is observed in the solid state seems to be only transient in solution There are many compounds similar to this compound(75732-01-3)Synthetic Route of C9H11Cu. if you want to know more, you can check out my other articles.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called [(MesCu)2(η3-Si4)]4-: A Mesitylcopper-Stabilized Tetrasilicide Tetraanion, published in 2010, which mentions a compound: 75732-01-3, mainly applied to mesityl copper stabilized tetrasilicide tetraanion preparation crystal mol structure; mol structure calculation copper stabilized tetrasilicide tetraanion; Zintl anion, Computed Properties of C9H11Cu.

The formation of [(MesCu)2Si4]4- (3a) shows that highly charged silicon clusters can be obtained and handled in solution The title anion fills the gap between alkylated Si4R4 cage mols. and the (Si4)4- clusters in binary Zintl phases. The coordination of the MesCu fragment is comparable to the coordination of copper(I) to tetrahedral P4 as it has been reported in [Cu(P4)2]+. The copper atom bridges two P4 mols. which coordinate in η2 fashion. The coordinated P-P bond is also elongated by approx. 0.2 Å compared to the other P-P distances. The [Cu(P4)2]+ ion has been obtained only in the presence of weakly coordinating counter anions. The results show that related ions can be obtained even in the presence of strongly coordinating solvent mols. such as NH3.

HPLC of Formula: 75732-01-3. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. 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.
