Reference of Mesitylcopper(I). So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about An Expeditious Synthesis of Sialic Acid Derivatives by Copper(I)-Catalyzed Stereo-divergent Propargylation of Unprotected Aldoses.

We developed a copper(I)-catalyzed stereo-divergent anomeric propargylation of unprotected aldoses as a facile synthetic pathway to a broad variety of sialic acid derivatives The soft allenyl-copper(I) species, catalytically generated from stable allenyl-boronic acid pinacolate, is unusually inert to protonolysis by the multiple hydroxy groups of the substrates and thereby functions as a carbon nucleophile. The key additive B(OMe)3 facilitated ring-opening of the non-electrophilic cyclic hemiacetal forms of aldoses to the reactive aldehyde forms. The chirality of the catalyst, and not the internal stereogenic centers of substrates, predominantly controlled the stereochem. of the propargylation step; i.e., the diastereoselectivity was switched simply by changing the catalyst chirality. This is the first non-enzyme catalyst-controlled stereo-divergent C-C bond elongation at the anomeric center of unprotected aldoses, which contain multiple protic functional groups and stereogenic centers. The propargylation products can be expeditiously transformed into naturally occurring and synthetic sialic acid derivatives in a simple three-step sequence. This synthetic method, which requires no protecting groups, can be performed on a gram-scale and thus offers general and practical access to various sialic acid derivatives from unprotected aldoses.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Mesitylcopper(I)(SMILESS: [Cu]C1=C(C)C=C(C)C=C1C,cas:75732-01-3) is researched.HPLC of Formula: 56413-95-7. The article 《Bis(2-phenylethyl)-nacnac: A Chiral Diketiminate Ligand and Its Copper Complexes》 in relation to this compound, is published in Organometallics. Let’s take a look at the latest research on this compound (cas:75732-01-3).

The chiral diketiminate ligand bis-N,N’-(2-phenylethyl)-2,4-diiminopentane, 1H, was synthesized in good yields in a 1-step reaction from chiral amine and acetylacetone. Reaction of 1Li(THF) with N-bromosuccinimide yielded the succinimide-substituted ligand 2H. Cu complexes were obtained by reaction of the ligand with a basic Cu source in the presence of coordinating Lewis bases, and 1Cu(NCMe), 1Cu(DMAP), 1Cu(PPh3), 1Cu(2,6-xylyl isonitrile), 2Cu(PPh3), and 2Cu(2,6-xylyl isonitrile) were prepared and, for the most part, characterized by x-ray diffraction studies. Compared to their more common analogs with aromatic substituents on N, 1 and 2 seem to be more basic (1 > 2) and sterically more demanding (2 > 1). Their Cu complexes are less stable than those of aryl-substituted diketiminates and tend to decompose by disproportionation, most probably after dissociation of the coordinated Lewis base. Despite the rotational freedom around the N-R* bond, the complexes are sterically rigid, a necessary requirement for potential applications in enantioselective catalysis.

Author is Parab, Kshitij; Venkatasubbaiah, Krishnan; Jaekle, Frieder.

A new class of highly fluorescent triarylborane polymers was prepared from trimethylsilyl-substituted polystyrene via a modular approach that involves selective polymer modification reactions with organometallic reagents. The photophys. properties, environmental stability, and the Lewis acidity of the boron sites were tailored through modifications in the substitution pattern on boron. The photophys. properties are indicative of electronic communication between the chromophores attached to polystyrene, which was exploited for the efficient probing of fluoride and cyanide in the micromolar concentration range.

D.; Javed, Saba; Hoffman, David M..

Copper(I) chloride reacted with lithium ketimides to form tetrameric homoleptic copper(I) ketimide complexes, [Cu(N:CR2)]4, where R = t-Bu or Ph. Mesityl copper reacted with excess 1-trimethylsilylmethyl-2,2,-dimethylhydrazine to give the mixed ligand complex (2,4,6-C6Me3H2)Cu4[N(SiMe3)NMe2]3. Single-crystal x-ray crystallog. studies revealed that the three complexes have eight-member ring structures in which the ring has a hinged or butterfly shape. Although an eight-member ring structure is common for copper(I) amido, alkyl, and aryl clusters, the structure of [Cu(N:C-t-Bu2)]4 is unusual because the hinge angle is significantly smaller than is common, resulting in short Cu···Cu contacts compared to related complexes.

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. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Reactivity of Liquid Ammonia Solutions of the Zintl Phase K12Sn17 towards Mesitylcopper(I) and Phosphinegold(I) Chloride.COA of Formula: 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.

Homoat. polyanions of post-transition main-group metals, namely, Zintl anions, are precast in analogous Zintl phases and can react in solution to form new materials. Despite comprehensible reaction approaches, the formed products cannot be planned in advance, as hitherto undetected and therefore disregarded side reactions take place. The outcomes and interpretations of the reactions of Zintl anions are so far based mainly on crystal structures, which only allow characterization of the product that has the lowest solubility Here the authors present the results of their investigation of the stability of highly charged tin Zintl anions in liquid ammonia, which is not exclusively based on solution effects but also on the oxidative influence of the solvent. This allows for a deeper understanding of the ongoing processes in solution and opens doors to the directed synthesis of transition metal complexes of Sn44-, here shown by its reactivity towards MesCu.
