The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Chloro(1,5-cyclooctadiene)copper(I) dimer( cas:32717-95-6 ) is researched.Related Products of 32717-95-6.Verma, Pritha; Richter, Jeremy M.; Chekshin, Nikita; Qiao, Jennifer X.; Yu, Jin-Quan published the article 《Iridium(I)-Catalyzed α-C(sp3)-H Alkylation of Saturated Azacycles》 about this compound( cas:32717-95-6 ) in Journal of the American Chemical Society. Keywords: saturated azacycle regioselective alkylation alkene iridium amidoxime directing group; iridium regioselective alkylation catalyst. Let’s learn more about this compound (cas:32717-95-6).

Saturated azacycles are commonly encountered in bioactive compounds and approved therapeutic agents. The development of methods for functionalization of the α-methylene C-H bonds of these highly privileged building blocks is of great importance, especially in drug discovery. While much effort has been dedicated towards this goal of using a directed C-H activation approach, the development of directing groups that are both general, as well as practical, remains a significant challenge. Herein, the design and development of novel amidoxime directing groups is described for Ir(I)-catalyzed α-C(sp3)-H alkylation of saturated azacycles using readily available olefins as coupling partners. This protocol extends the scope of saturated azacycles to piperidines, azepane, and tetrahydroisoquinoline that are incompatible with our previously reported directing group. A variety of olefin coupling partners, including previously unreactive di-substituted terminal olefins and internal olefins, are compatible with this transformation. The selectivity for a branched α-C(sp3)-alkylation product is also observed for the first time when acrylate is used as the reaction partner. The development of practical, one-step installation and removal protocols further add to the utility of amidoxime directing groups.

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: 32717-95-6, is researched, Molecular C16H16Cl2Cu2, about Synthesis, structural characterization, and bonding analysis of two-coordinate copper(I) and silver(I) complexes of pyrrole-based bis(phosphinimine): new metal-pyrrole ring π-interactions, the main research direction is copper silver pyrrole phosphinimine complex preparation crystal mol structure; electron density aromaticity copper silver pyrrole phosphinimine complex.Category: quinoxaline.

The reaction between 2,5-bis(diphenylphosphinomethyl)pyrrole and Me3SiN3 gave the new pyrrole-based bis(phosphinimine) L1H in an excellent yield. L1H reacts with [CuCl(COD)]2, AgBF4, or AgOTf to give the corresponding two-coordinate mononuclear ionic complex formulated as [M{(L1H)-κ2N,N}]+[X]- where M = Cu and Ag; X = [CuCl2], BF4 or OTf. Their single crystal x-ray diffraction studies confirmed the two-coordinate geometry formed by the chelate bonding mode of L1H. These 10-membered metalacycles exhibit planar chirality and were also characterized by spectroscopic methods. In addition, in all three structures, there exists a hitherto unknown π-interaction between the pyrrole ring atoms and metal, represented as η2-(Cα-N) in the copper(I) complex, and η3-(Cα-N-Cα’) in the silver(I) complexes. These weak interactions were supported by DFT calculations in terms of their electron densities, non-covalent interaction plots and the decrease in the aromaticity of the pyrrole ring.

No major difference was found between Rh- and Ir-catalyzed homogeneous carbonylation of MeOH to HOAc, using MeI as promoter. The dependence of the activity on the nature of the Ir based catalyst is greater than that of th Rh-based catalyst, and the maximum activity occurs at different conditions. Rh(CO)2I2- and Ir(CO)2I2- are the catalytic species in these reactions and the Ir complexes are the best catalysts of all the Pt metal complexes. The mechanism of the reaction is discussed.

Tripodal indolyl phosphine ligands, P(X1PR2)3 (1, 2; X = 3-methyl-1,2-indolediyl; R = Ph, iPr) and P(X2PPh2)3 (3, X2 = 3-methyl-2,1-indolediyl) were prepared by lithiation and phosphination of 3-methylindole; crystal structures, catalytic activity and reactivity of Cu(I), Rh(I) Rh(II) complexes of 1-3 were explored. The high-yielding synthesis and detailed characterization of two well-defined, linkage isomeric tripodal, tetradentate all-phosphorus ligands 1-3 is described. Coordination to Cu(I) resulted in formation of complexes [CuCl[P(X1PR2-κP)2(X1PR2)-κP]] (4, 5, R = Ph, iPr) and [CuCl[P(X2PR2-κP)2(X2PR2)-κP]] (6), for which the mol. structures indicate overall tridentate coordination to the copper atom in the solid state, with one dangling peripheral phosphine. The solution studies suggest fast exchange between the three phosphine side-arms. These new CuI complexes 4-6 catalyze cyclopropanation of styrene with ethyldiazoacetate (EDA), yielding Et 2-phenylcyclopropanecarboxylate with 70:30 trans:cis-selectivity. The anticipated well-defined tetradentate coordination in a C3-sym. fashion was achieved with RhI and IrI, leading to the overall five-coordinated complexes [MCl[P(X1PR2-κP)3-κP]] (7, 9, M = Rh, Ir), [MCl[P(X2PR2-κP)3-κP]] (8, 10, M = Rh, Ir), [Rh(L)[P(X1PR2-κP)3-κP]][BF4] (11, 12, L = η2-norbornadiene, CO).
