  Study of the electrochemical deposition of Sn–Ag–Cu alloy by cyclic voltammetry and chronoamperometry

  摘要：

  The electrochemical deposition of Sn-Ag-Cu alloy from weakly acidic baths onto glassy carbon electrodes (GCE) was studied by cyclic voltammetry (CV) and chronoamperometry (CA). The properties of the electrodeposits were characterized by scanning electron microscopy (SEM), energy-dispersive spectrometery (EDS) and X-ray diffraction (XRD). Test results indicate that the two cathodic peaks in the CV curves, at -0.6 V and -0.85 V during the forward scan towards the negative potentials, correspond to the irreversible deposition of a solid solution of tin, silver and copper. The underpotential deposition (UPD) of Sn occurs at -0.6V during the cathodic period and the amount of Ag and Cu in the Sn-Ag-Cu alloy decreases with increasingly negative cathodic potentials. During the forward scan, towards the positive potentials used in CV testing, cathodic peaks at -0.85V appear in the CV curves for baths containing mixtures of tin salts and triethanolamine (TEA). This corresponds to a reduction of transient complex ions [Sn(TEA)(x)](2+) on the surface of the cathode. Furthermore, the formation and reduction of [Sn(TEA)(x)](2+) is a diffusion controlled process. On the surface of the GCE, the actual nucleus growth mechanism of the Sn-Ag-Cu alloy is represented by the progressive nucleation model. (C) 2008 Elsevier Ltd. All rights reserved.

  Cu-Catalyzed Fluorination of Diaryliodonium Salts with KF

  摘要：

  A mild Cu-catalyzed nucleophilic fluorination of unsymmetrical diaryliodonium salts with KF is described. This protocol preferentially fluorinates the smaller aromatic ligand on Iodine(III). The reaction exhibits a broad substrate scope and proceeds with high chemoselectivity and functional group tolerance. DFT calculations implicate a Cu-I/Cu-III catalytic cycle.

  The thermal decompositions of dehydrated or anhydrous bivalent transition metal (Mn, Fe, Co, Ni, Cu, Zn, Cd) and alkali rare metal (Mg, Ca, Sr, Ba) methanesulfonates were studied by TG/DTG, IR and XRD techniques in dynamic Air at 250–850 °C. The initial decomposition temperatures were calculated from TG curves for each compound, which show the onsets of mass loss of methanesulfonates were above 400 °C. For transition metal methanesulfonates, the pyrolysis products at 850 °C were metal oxides. For alkali rare metal methanesulfonates, the pyrolysis products at 850 °C of Sr and Ba methanesulfonates were sulphates, while those of Mg and Ca methanesulfonate were mixtures of sulphate and oxide.

  Crystals of poly-bis(pyrazine)bis(methanesulfonato-O)copper(II) are orthorhombic, a = 8.199(1), b = 13.130(1), c = 6.913(1) Å, Z = 2, space group Pnnm. The structure was solved by conventional heavy atom methods and was refined by full-matrix least-squares procedures to R = 0.025 and R_w = 0.033 for 1226 reflections with I ≥ 3σ(I). The complex contains parallel sheets, each sheet consisting of a square array of copper(II) ions bridged by two types of bidentate pyrazine ligands. The CuN₄O₂ chromophore is tetragonally elongated; the equatorial plane contains two pyrazine nitrogen atoms (Cu—N(1) = 2.058(2) Å) and two oxygen atoms from monodentate methanesulfonate ligands (Cu—O(1) = 1.956(1) Å); the axial sites are occupied by bridging pyrazine groups with significantly longer Cu—N bond lengths (Cu—N(2) = 2.692(2) Å) Magnetic susceptibility studies (82 to 4.2 K) reveal antiferromagnetic behaviour with a susceptibility maximum at about 6.2 K. Exchange coupling in the complex is considered to take place primarily via the more strongly bound, equatorially coordinated pyrazine ligands. Analysis of the magnetic susceptibility data according to a Heisenberg linear chain of interacting S = 1/2 spins yields best fit values of J = −3.82 cm⁻¹ and g = 2.13. Vibrational and electronic spectroscopic and differential scanning calorimetric studies on the title compound and, for comparison, on the related mononuclear pyridine complex, bis(methanesulfonato)-tetrakis(pyridine)copper(II), are also reported.
