The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Organoborane Acceptor-Substituted Polythiophene via Side-Group Borylation. Author is Li, Haiyan; Sundararaman, Anand; Venkatasubbaiah, Krishnan; Jaekle, Frieder.

Organoborane acceptor-modified polythiophene was prepared from silylated polythiophene via a new polymer modification strategy. The attachment of electron-deficient dimesitylboryl groups leads to a significant decrease of the LUMO levels as evidenced by a strong bathochromic shift in the UV-visible absorption and emission spectra and the observation of reversible reduction waves in the cyclic voltammogram at significantly less cathodic potentials than for the silylated precursor polymer. The modification of conjugated polymers with electron-deficient boryl groups provides a new design principle for the preparation of electronically interesting materials.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 75732-01-3, is researched, Molecular C9H11Cu, about Toward absolute asymmetric synthesis of coordination polymers with bidentate sulfide ligands, the main research direction is copper halo mesityl sulfide complex preparation crystal structure.Application of 75732-01-3.

In search for sulfide-containing coordination polymers that crystallize as conglomerates, five new copper(I) complexes with prochiral sulfide ligands were prepared and characterized by single crystal x-ray structure determination Three unsym. sulfides were used: Ph propargyl sulfide (Sprop), allyl Me sulfide (Sally), and 2,5-dithiahexane (SS). In [CuCl(Sprop)]n (1), layers are formed via π-coordination of propargyl groups to copper(I). In [Cu2Br2(Sprop)4] (2), discrete dimers form with non-coordinating propargyl groups. In [CuCl(Sally)]n (3), layers are formed via π-coordination of allyl groups to copper(I), but disordered Sally ligands are also found. The mesitylcopper complex [Cu4(Mes)4(Sally)2] (4) is chiral but discrete. In [Cu4(Mes)4(SS)]n (5), racemic chains are formed by the SS ligand. Three out of five complexes prepared thus form coordination polymers, and all of the five complexes (1-5) exhibit terminal sulfide ligands that could be oxidized selectively when incorporated in an enantiopure polymer. Unfortunately none of 1-5 crystallized as a conglomerate, but whether this reflects an inherent tendency in this system is too early to say.

Li organoamidocuprates LiCuR(NR’2) are an important class of organocopper reagents and found widespread application in conjugate addition and other bond-forming reactions. The dependence of the structures and equilibrium of these species on the steric and electronic properties of the amido group is reported in both the solid state and in solution Three different cuprate complexes were crystallog. characterized: the organoamidocuprate [Cu2Li2Mes2TMP2] (2) (TMP = 2,2,6,6-tetramethylpiperidide) which is shown to adopt a head-to-tail conformation; [Cu2Li2(N(CH2Ph)CH2CH2NMe2)4] (3) which is a homoamidocuprate and contains addnl. coordination of the Li centers from intra-mol. tertiary amine groups; and the diastereomeric organoamidocuprate [Cu2Li2Mes2(N(R-CH(Ph)Me)(CH2CF3))2] (4) which adopts a head-to-head conformation. Complex 4 is unique in being the 1st crystallog. characterized example of a head-to-head isomer of a heterocuprate, and its structure also has implications for the use of scalemic amidocuprates in asym. induced conjugate addition The solution equilibrium of all new complexes also were studied using 7Li NMR spectroscopy, and in each case the species observed in the crystal structure was shown to also be the predominant isomer in solution

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 Homoleptic Copper(I) Alkoxide and Phenoxide Clusters Stabilized by Intramolecular π-Coordination: Tetrameric o-Allylphenoxocopper(I) and Hexameric 2-Methyl-3-buten-2-oxocopper(I), published in 1998-01-19, which mentions a compound: 75732-01-3, mainly applied to copper alkoxide phenoxide cluster intramol stabilized; tetrameric allylphenoxocopper hexameric methylbutenoxocopper preparation structure, COA of Formula: C9H11Cu.

Built-in π-alkene functionalities have been found to yield homoleptic copper(I) phenoxide and alkoxide clusters exhibiting tetrameric cubane- or hexameric ribbon-shaped structures. While tetrameric o-allylphenoxocopper(I) (1) is remarkably stable, retains its structure in solution, and resists carbonylation, hexameric methylbutenoxocopper(I) (2) dissolves in such a way that oxo-bridged copper(I) is retained, whereas π-alkene-copper(I) coordination is destroyed, leaving copper(I) free to accept carbon monoxide as a ligand.

Author is Krieck, Sven; Goerls, Helmar; Westerhausen, Matthias.

The addition of [(L)4Ca(I)Mes] (Lewis base L = thf, Et2O) to mesityl copper(I) and the transmetalation reaction of mesityl copper(I) with activated calcium are suitable pathways for the synthesis of dimesityl cuprates(I) of calcium. However, the structures of the calcium cuprates(I) depend on the preparative procedure. The transmetalation reaction leads to the formation of [Mes-Cu-Mes]- anions whereas the addition yields dinuclear [(Mes-Cu)2(μ-Mes)]- anions. The solvent-separated counterions are [Ca(thf)6]2+ and [(thf)5CaI]+, resp. In contrast to these findings, the addition of [(L)4Ca(I)Mes] to mesityl copper(I) in an Et2O/toluene mixture led to formation of tetrameric solvent-free iodocalcium dimesityl cuprate(I) [ICa(μ-η1,η6-Mes2Cu)]4, representing a rare example of a heavy Normant-type organocuprate.

Chem. charging of single-walled carbon nanotubes (SWCNTs) and graphenes to generate soluble salts shows great promise as a processing route for electronic applications, but raises fundamental questions. The reduction potentials of highly-charged nanocarbon polyelectrolyte ions were investigated by considering their chem. reactivity towards metal salts/complexes in forming metal nanoparticles. The redox activity, degree of functionalisation and charge utilization were quantified via the relative metal nanoparticle content, established using thermogravimetric anal. (TGA), inductively coupled plasma at. emission spectroscopy (ICP-AES) and XPS. The fundamental relationship between the intrinsic nanocarbon electronic d. of states and Coulombic effects during charging is highlighted as an important area for future research.

Computed Properties of C9H11Cu. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Highly Fluorinated Weakly Coordinating Monocarborane Anions. 1-H-CB11F11-, 1-CH3-CB11F11-, and the Structure of [N(n-Bu)4]2[CuCl(CB11F11)]. Author is Ivanov, Sergei V.; Rockwell, Juston J.; Polyakov, Oleg G.; Gaudinski, Christine M.; Anderson, Oren P.; Solntsev, Konstantin A.; Strauss, Steven H..

Treatment of CsCB11H12 with F2 in anhydrous HF produced Cs(1-H-CB11F11) in 74% isolated yield. The polyfluorocarborane anion was stable in 5 M aqueous acid. It is deprotonated in 3 M aqueous base but only slowly undergoes F/OH metathesis in this medium. Salts of 1-CH3-CB11F11- were prepared by treating salts of 1-H-CB11F11- with di-Me sulfate in basic solution Neither 1-H-CB11F11- nor 1-CH3-CB11F11- reacted with ≥20-fold excess triethylaluminum. The compound Si(i-Pr)3(1-CH3-CB11F11) was generated in toluene solution and was found to exhibit a δ(29Si) value of 120.0, the highest pos. value yet observed for any Si(i-Pr)3X species. On this basis, the 1-H-CB11F11- and 1-CH3-CB11F11- anions show great promise as robust, chem. inert, weakly coordinating anions. The crystalline compound [NBu4]2[CuCl(CB11F11)] was formed when [Cu(mesityl)]n was treated with one equiv [NBu4][1-H-CB11F11] and one equiv NBu4Cl. The Cu(I) coordination geometry in the [CuCl(CB11F11)]2- anion, determined by x-ray crystallog., is two-coordinate linear, with Cu-Cl = 1.917(5) Å, Cu-Cl = 2.136(1) Å, and Cl-Cu-Cl = 176.0(2)°.
