Author is Weidner, Karin; Sun, Zhongdong; Kumagai, Naoya; Shibasaki, Masakatsu.

α-Azido 7-azaindolinylamide I underwent diastereoselective and enantioselective aldol additions to ortho-substituted aryl aldehydes 2-RC6H4CHO (R = F3C, Br, I, O2N, PhCC, F) in the presence of mesitylcopper and either a nonracemic bis(diphenylphospholanyl)ethane or a nonracemic bis(diarylphosphino)binaphthalene ligand to yield either nonracemic syn- or anti-α-azido-β-hydroxy acyl 7-azaindolinylamides such as II (R = F3C, Br, I, O2N, PhCC, F; R1 = N3, H; R2 = H, N3) in 74-98% yields, 53:47->98:2 dr, and 89-99% ee. Aromatic aldehydes lacking ortho substituents underwent diastereoselective and enantioselective aldol addition reactions with I to yield syn-α-azido-β-hydroxy amides only. Alkynals underwent diastereoselective and enantioselective aldol addition reactions with I to yield anti-α-azido-β-hydroxy amides; aldol addition of I to hydrocinnamaldehyde gave product with no diastereo- or enantioselectivity. II (R = F3C; R1 = N3; R2 = H) was converted to the corresponding nonracemic α-azido-β-hydroxy carboxylic acid and Me carboxylate and to a nonracemic 3-aryl-2-aziridinecarboxylic acid; the 7-azaindoline byproduct could be recovered. The structures of II (R = F3C, PhCC; R1 = N3; R2 = H), an aziridine derived from II (R = F3C; R1 = N3; R2 = H), and the tert-Bu carbonate ester of a racemic anti-α-azido-β-hydroxy 7-azaindolinylamide derived from 3-(4-fluorophenyl)-2-propynal were determined by X-ray crystallog.

Recommanded Product: Mesitylcopper(I). The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Copper/α-Ketocarboxylate Chemistry With Supporting Peralkylated Diamines: Reactivity of Copper(I) Complexes and Dicopper-Oxygen Intermediates. Author is Gupta, Aalo K.; Tolman, William B..

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.

Author is Helgadottir, I. S.; Arquilliere, P. P.; Brea, P.; Santini, C. C.; Haumesser, P.-H.; Richter, K.; Mudring, A.-V.; Aouine, M..

Ionic liquids (ILs) can be used to generate and stabilize metallic nanoparticles (MNPs) by several phys. and chem. routes. Here, the simultaneous decomposition of Ru and Cu organometallic precursors in IL is shown to yield core-shell Ru@CuNPs with smaller diameters and narrower size distributions than the corresponding monometallic NPs, in a broad range of Ru:Cu compositions They are probably formed by rapid nucleation of Ru cores followed by decomposition of the Cu precursor on their surface. This effect forces the formation of a bimetallic structure that does not form with the use of purely phys. processes such as PVD. These Cu, Ru, and Ru@CuNPs could be used for the formation of seed and barrier layers for the metalization of advanced interconnect structures.

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.

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 Reactivity of Liquid Ammonia Solutions of the Zintl Phase K12Sn17 towards Mesitylcopper(I) and Phosphinegold(I) Chloride, published in 2014, which mentions a compound: 75732-01-3, mainly applied to preparation heterometallic tin gold copper cluster Zintl anion; crystal structure heterometallic tin gold copper cluster Zintl anion; alkali metal tin Zintl phase reactivity mesitylcopper chlorophosphinegold; Zintl anions; cluster compounds; copper; structure elucidation; tin, Computed Properties of C9H11Cu.

To gain more insight into the reactivity of intermetalloid clusters, the reactivity of the Zintl phase K12Sn17, which contains [Sn4]4- and [Sn9]4- cluster anions, was investigated. The reaction of K12Sn17 with gold(I) phosphine chloride yielded K7[(η2-Sn4)Au(η2-Sn4)](NH3)16 (1) and K17[(η2-Sn4)Au(η2-Sn4)]2(NH2)3(NH3)52 (2), which both contain the anion [(Sn4)Au(Sn4)]7- (1a) that consists of two [Sn4]4- tetrahedra linked through a central gold atom. Anion 1a represents the first binary Au-Sn polyanion. From this reaction, the solvate structure [K([2.2.2]crypt)]3K[Sn9](NH3)18 (3; [2.2.2]crypt = 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) was also obtained. In the analogous reaction of mesitylcopper with K12Sn17 in the presence of [18]crown-6 in liquid ammonia, crystals of the composition [K([18]crown-6)]2[K([18]crown-6)(MesH)(NH3)][Cu@Sn9](THF) (4) were isolated ([18]crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadiene, MesH = mesitylene, THF = tetrahydrofuran) and featured a [Cu@Sn9]3- cluster. A similar reaction with [2.2.2]crypt as a sequestering agent gave crystals of [K[2.2.2]crypt][MesCuMes] (5). The cocrystn. of mesitylene in 4 and the presence of [MesCuMes]- (5a) in 5 provides strong evidence that the migration of a bare Cu atom into an Sn9 anion takes place through the release of a Mes- anion from mesitylcopper, which either migrates to another mesitylcopper to form 5a or is subsequently protonated to give MesH.

Now I present to you an article called Copper(I) Siloxides – Aggregated Solid-State Structures, Cu-Cu Interactions and Dynamic Solution Behavior, published in 2012, which mentions a compound: 75732-01-3, mainly applied to aggregated copper siloxide preparation crystal mol structure; dynamic solution behavior aggregated copper siloxide; mol structure calculation aggregated copper siloxide, Recommanded Product: 75732-01-3.

Reaction of the siloxane-diols HO(Ph2SiO)2H, 1,1,3,3-tetraphenyldisiloxane-1,3-diol (L1H2), HO(iPr2SiO)2H, 1,1,3,3-tetraisopropyldisiloxane-1,3-diol (L2H2), and HO(Ph2SiO)3H, 1,1,3,3,5,5-hexaphenyltrisiloxane-1,5-diol (L3H2) with two equivalent of CunMesn led to octanuclear compounds [Cu8L14] (1), [Cu8L24] (2), and [Cu8L12L*2] [L* = O(Ph2SiO)4] (3), which were characterized by single-crystal x-ray diffraction anal. as well as by solution NMR spectroscopy. The crystal structures revealed that all the compounds are composed of Cu4O4 moieties featuring short Cu-Cu distances that can be discussed in terms of cuprophilic interactions. Two such units are linked via four disiloxane units in 1 and 2, in 3 they are connected by two equivalent of (L1)2-. Formation of 3 required disproportion of a trisiloxane-1,5-diolate to give a disiloxane-1,3-diolate and a tetrasiloxane-1,7-diolate, and thus indicates that siloxane units are not inert under the synthetic conditions employed. NMR spectroscopic investigations of the structure of 1 in solution revealed an equilibrium, presumably with [Cu4L22] fragments. Crystallization of a structural isomer of 3 indicates a shallow potential energy surface for this compound
