Copper(I) complexes of 8-(diphenylphosphanyl-oxy)-quinoline: Photophysics, structures and reactivity

Copper(I) complexes are studied for various potential applications due to their luminescence properties. However, issues have been identified regarding the stability of heteroleptic compounds. As a novel strategy, we propose to modify existing copper(I) complexes by introduction of molecular bridges between the different ligands. We report the synthesis and chemical properties of the complexes of 8-(diphenylphosphanyl-oxy)quinoline (POQ), a combination of a phosphine and a N-heterocycle with CuX (X = Cl, Br, I and SCN). The photophysical properties of the materials were studied. However, all four compounds were found to be labile in solution upon contact with trace amounts of water. Two POQ complexes and the decomposition products were identified as tetraphenyldiphosphoxane complexes with single crystal X-ray diffraction. We propose a design rule to prevent this behavior in future development steps.

Aryl Sulfonium Salts for Site-Selective Late-Stage Trifluoromethylation

Incorporation of the CF3 group into arenes has found increasing importance in drug discovery. Herein, we report the first photoredox-catalyzed cross-coupling of aryl thianthrenium salts with a copper-based trifluoromethyl reagent, which enables a site-selective late-stage trifluoromethylation of arenes. The reaction proceeds with broad functional group tolerance, even for complex small molecules on gram scale. The method was further extended to produce pentafluoroethylated derivatives.

Copper(II)-mediated oxime-nitrile coupling in non-aqueous solutions: Synthetic, structural and magnetic studies of the copper(II)-salicylaldehyde oxime reaction system

The reactions of salicylaldehyde oxime (H2salox) with Cu II precursors yielded the known complexes [Cu(Hsalox)2] (1) and [Cu(Hsalox)2]n (2), as well as complexes [Cu 3(salox)(L1)(L2)]¡¤MeCN (3¡¤MeCN), [CuCl(L1)] (4) and [Cu2Na(O2CMe) 5(HO2CMe)]n (5), where L1 – = o-O-C6H4-CHNO-C(CH3)NH and L23- = o-O-C6H4-CHNO-C(o-O-C 6H4)N. L1- was formed in situ via the nucleophilic addition of the oximato O-atom of salox2- to the unsaturated nitrile group of the MeCN reaction solvent. L2 3- is also formed in situ probably through the nucleophilic attack of the oximato O-atom to the unsaturated nitrile group of salicylnitrile; the latter, although not directly added to the reaction mixture, can be produced via the dehydration of salox2-. Compounds 1 and 2 contain Hsalox – bound to the metal center in two different coordination modes; they both contain the same mononuclear unit, however a 2D network is generated in 2 due to a relatively long Cu-Ooximato bond. Compound 3 contains three different ligands, i.e. salox2-, L1- and L 23-, which act as mu3-kappa2O: kappaO?:kappaN, kappaO:kappaN:kappaN? and mu3-kappa2O:kappa2N:kappaO?: kappaN?, respectively, whereas 4 consists of a square planar Cu II atom bound to a kappaO:kappaN:kappaN? L 1- and a chloride ion. Compound 5 consists of dinuclear [Cu2(O2CMe)5(HO2CMe)]- units and Na+ ions assembled into an overall 3D network structure. Magnetic susceptibility measurements from polycrystalline samples of 2 and 5 gave best-fit parameters J = +0.36 cm-1 (H = -JS? iS?j) and J = -360 cm-1, zj = +20 cm -1 (H = -JS?iS?j – zJ?S z?S?z), respectively.

Copper catalyzed oxidative coupling of ortho-vinylanilines with N-tosylhydrazones: Efficient synthesis of polysubstituted quinoline derivatives

Efficient and general copper catalyzed oxidative cyclization of ortho-vinylaniline has been accomplished employing N-tosylhydrazone as coupling partner. Various substituted quinoline derivatives of biological importance were achieved in good to excellent yield. The important features are the high functional group tolerates, up-gradation to gram scale synthesis and possible one-pot synthesis of quinoline from corresponding carboxaldehyde. Synthetic potential of the obtained quinoline derivatives was demonstrated through C-H bond functionalization reaction. Furthermore, preliminary mechanistic investigation revealed the possible generation of non-stabilized diazo compound and imine derivative as potential intermediates as well as copper catalyzed electrocyclic reaction and oxidative aromatization.

Versatility of the nature of the magnetic Cu(II)-U(IV) interaction. Syntheses, crystal structures and magnetic properties of Cu2U and CuU compounds

Treatment of [M(H2Li)] with U(acac)4 in refluxing pyridine led to the formation of the trinuclear complexes [{MLi(py)x}2U] [L1 = N,N?-bis(3-hydroxysalicylidene)-2,2-dimethyl-1,3-propanediamine and M = Ni, Cu or Zn; L2 = N,N?-bis(3-hydroxysalicylidene)-1,3-propanediamine and M = Cu or Zn; L3 = N,N?-bis(3-hydroxysalicylidene)-2-methyl-1,2-propanediamine and M = Ni, Cu or Zn; x = 0 or 1]. The dinuclear compounds [ML3(py)U(acac)2] (M = Cu, Zn) were isolated from the reaction of [M(H2L3)] and U(acac)4 in pyridine at 60C. The crystal structures of the trinuclear complexes are built up by two orthogonal MLi(py)x units which are linked to the central uranium ion by the two pairs of oxygen atoms of the Schiff base ligand; the U(IV) ion is found in the same dodecahedral configuration but the Cu(II) ion coordination geometry and the Cu … U distance are different by passing from L1 or L2 to L3, due to the shortening of the diimino chain of L3. These geometrical parameters seem to have a great influence on the magnetic behaviour of the complexes since the Cu-U coupling in [{CuLi(py)x}2U] (i = 1, 2) is ferromagnetic while it is antiferromagnetic in [{CuL3(py)x}2U]. In the compounds [{CuL3(py)x}2U] and [CuL3(py)U(acac)2], the Cu coordination and the Cu … U distance are very similar, and both exhibit an antiferromagnetic interaction.

Separation of propylene and propane by alkylimidazolium thiocyanate ionic liquids with Cu+ salt

Ionic liquids (ILs) coupled with Ag+ or Cu+ salts to form a new kind of reactive absorbent have been studied to separate light olefin from paraffin recently. In this work, we prepared two halogen-free alkylimidazolium thiocyanate ILs with cheaper cuprous thiocyanate, i.e., [Bmim]SCN-CuSCN and [Emim]SCN-CuSCN (Bmim, 1-butyl-3-methylimidazolium; Emim, 1-ethyl-3-methylimidazolium) and investigated their absorption capability for propylene, propane and mixture of both at 1-7 bar and 298-318 K. The effects of operating parameter including cation nature, temperature, pressure, Cu+ concentration and reuse of absorbent were investigated. Propylene shows a chemical absorption while propane does a physical one, and increasing Cu+ concentration effectively improves the absorption capability for propylene and the selectivity of propylene/propane. [Bmim]SCN-CuSCN has higher absorption capability and selectivity for propylene than [Emim]SCN-CuSCN, e.g., [Bmim]SCN-CuSCN-1.5 M can absorb 0.12 mol of propylene per liter while 0.012 mol of propane per liter at 1 bar and 298 K, with a selectivity of 10, which is comparable to some other ILs-Ag+ salts and better than pure ILs. Such absorbents can be regenerated through temperature and pressure swing without remarkable activity loss. This work shows that alkylimidazolium thiocyanate ILs with Cu+ salts are promising reactive absorbents to separate propylene from propane.
