Increasing structure dimensionality of copper(I) complexes by varying the flexible thioether ligand geometry and counteranions

This work focuses on the systematic investigation of the influences of pyrimidine-based thioether ligand geometries and counteranions on the overall molecular architectures. A N-containing heterocyclic dithioether ligand 2,6-bis-(2-pyrimidinesulfanylmethyl)pyridine (L1) and three structurally related isomeric bis(2-pyrimidinesulfanylmethyl)-benzene (L2-L4) ligands have been prepared. On the basis of the self-assembly of CuX (X = I, Br, Cl, SCN, or CN) and the four structurally related flexible dithioether ligands, we have synthesized and characterized 10 new metal-organic entities, Cu 4(L1)2I4 1, Cu4(L1) 2Br4 2, [Cu2(L2)2I 2¡¤CH3CN]n 3, [Cu(L3)I]n 4, [Cu(L3)Br]n 5, [Cu(L3)CN]n 6, [Cu(L4)CN]n 7, [Cu2(L4)I2]n 8, [Cu2(L4)(SCN) 2]n 9, and {[Cu6I5(L4) 3](BF4)¡¤H2O}n 10, by elemental analyses, IR spectroscopy, and X-ray crystallography. Single-crystal X-ray analyses show that the 10 Cu(I) complexes possess an increasing dimensionality from 0D (1 and 2) to 1D (3-5) to 2D (6-9) to 3D (10), which indicates that the ligand geometry takes an essential role in the framework formation of the Cu(I) complexes. The influence of counteranions and pi-pi weak interactions on the formation and dimensionality of these coordination polymers has also been explored. In addition, the photoluminescence properties of Cu(I) coordination polymers 4-10 in the solid state have been studied.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 1111-67-7, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1111-67-7, in my other articles.

Selective Construction of 2-Substituted Benzothiazoles from o-Iodoaniline Derivatives S8 and N-Tosylhydrazones

Selective construction of 2-substituted benzothiazoles from o-iodoaniline derivatives S8 and N-tosylhydrazone via a copper-promoted [3 + 1 + 1]-type cyclization reaction has been realized. In the protocol, the carbon atom on N-tosylhydrazone could be regulated to construct benzothiazole by changing the reaction system. Furthermore, the transformation has achieved the construction of multiple carbon-heteroatom bonds.

The structural definition of some novel adducts of stoichiometry CuX:dpex:MeCN (2:1:1)(n), X = (pseudo-) halogen, dppx = Ph2E(CH2)xEPh2, E = P, As, Sb

Single-crystal X-ray studies have defined the structures of a number of novel adducts of the form CuX:dpex (2:1), X = (pseudo-)halide, dpex = bis(diphenylpnicogeno)alkane, Ph2E(CH2)xEPh2, E = P, As, of diverse types, solvated with acetonitrile. CuBr:dpem (2:1)2. 2MeCN (E = both P, As) are tetranuclear, derivative of the familiar ‘step’ structure, while CuCl:dpph (MeCN solvate) and CuBr:dppe (MeCN solvate) yield one-dimensional polymers (i.e., x = 1, 2, 6 for dppx, x = m, e, h), as also does CuSCN:dpam (MeCN solvate). In CuI:dpsm:MeCN (3:1:2) (‘dpsm’ = Ph2Sb(CH2)SbPh2), CuI:dpsm (2:1)2 ‘step’ units are connected into an infinite ‘stair’ polymer by interspersed (MeCN)CuI linkers.

A study on solution deposited CuSCN thin films: Structural, electrochemical, optical properties

A cost-effective successive ionic layer adsorption and reaction (SILAR) method was used to deposit copper (I) thiocyanate (CuSCN) thin films on glass and steel substrates for this study. The deposited thin films were characterized for their structural, morphological, optical and electrochemical properties using X-ray diffraction (XRD), scanning electron microscopy (SEM), UV?visible spectroscopy and VersaSTAT potentiostat. A direct band gap of 3.88 eV and 3.6 eV with film thickness of 0.7 mum and 0.9 mum was obtained at 20 and 30 deposition cycles respectively. The band gap, microstrain, dislocation density and crystal size were observed to be thickness dependent. The specific capacitance of the CuSCN thin film electrode at 20 mV/s was 760 F g?1 for deposition 20 cycles and 729 F g?1 for deposition 30 cycles.

Mechanism and Models for Copper Mediated Nucleophilic Aromatic Substitution. 2. A Single Catalytic Species from Three Different Oxidation States of Copper in an Ullmann Synthesis of Triarylamines

Ullmann condensations of diarylamines with iodobenzenes has been investigated under homogeneous and a heterogeneous catalytic conditions with cupruos and cupric salts, as well as powered copper metal.Copper catalyzed condensation of diarylamines with iodoaromatics is relatively insensitive to substituent (for substituted iodobenzenes p=-0.25; for substituted diphenylamines p=1.09) but quite sensitive to halogen (k1/kBr.200).The first direct evidence for solution catalysis after filtration of a metal catalyzed reactions was obtained.Quantitative analysis of reaction rates, product yields, and catalyst characteristics leads to a comprehensive picture of the formation of soluble cuprous ions as the single active catalytic species under all conditions investigated.This hypothesis rationalizes many of the perplexing results which typify the literature associated with copper catalyzed nucleophilic aromatic substitution.
