      The cover picture shows a model structure of the human copper chaperone Atox1 bound to cisplatin (magenta: Pt; green: Cl; blue: N; white: H; yellow: S) and poses an intriguing question: Is platinum exchanged between transporters as it happens for copper? This major question is still lacking an answer. Details are presented in the Microreview by F. Arnesano, M. Losacco, and G. Natile on p. 2701 ff. For more on the story behind the cover research, see the Cover Profile. In the background is “the near-touching hands”, a detail of the Creation of Adam by Michelangelo.

      An Updated View of Cisplatin Transport (pages 2701–2711)

      Fabio Arnesano, Maurizio Losacco and Giovanni Natile

      Article first published online: 27 MAR 2013 | DOI: 10.1002/ejic.201300001

      Thumbnail image of graphical abstract

      Membrane transporters and soluble chaperones of copper ions mediate cellular uptake of and resistance to platinum-based drugs. In this microreview, the interactions of cisplatin with the methionine-rich motifs of the copper permease Ctr1 and with the cysteine motifs of the cytosolic copper chaperone Atox1 are described. Only in the latter case does the drug retain its ammine ligands essential for antitumor activity.

    2. Oxidation Catalysts

      Molybdenum versus Tungsten for the Epoxidation of Cyclooctene Catalyzed by [Cp*2M2O5] (pages 2728–2735)

      Pelin Sözen-Aktaş, Eric Manoury, Funda Demirhan and Rinaldo Poli

      Article first published online: 11 APR 2013 | DOI: 10.1002/ejic.201300260

      Thumbnail image of graphical abstract

      [Cp*2M2O5]-catalyzed (Cp* = pentamethylcyclopentadienyl) cyclooctene epoxidation is more efficient for M = Mo when the oxidant is tert-butyl hydroperoxide (TBHP)/decane, whereas it is more efficient for M = W when using H2O2/H2O. Water has a negative effect with both oxidants, and H2O2 is a better oxidant than TBHP for both metals, but the relative effects are system-specific.

    7. Zeolite-Encapsulated Manganese

      Electrochemical and Catalytic Studies of a Manganese(III)Complex with a Tetradentate Schiff-Base Ligand Encapsulated in NaY Zeolite (pages 2768–2776)

      Iwona Kuźniarska-Biernacka, Otilia Rodrigues, Maria Alice Carvalho, Pier Parpot, Krzysztof Biernacki, Alexandre Lopes Magalhães, Antonio Mauricio Fonseca and Isabel Correia Neves

      Article first published online: 4 APR 2013 | DOI: 10.1002/ejic.201201517

      Thumbnail image of graphical abstract

      Two methods for the encapsulation of a MnIIIsalen complex in NaY zeolite lead to different modes of coordination at the metal. Cyclic voltammetry of the neat and heterogeneous complexes shows different electrochemical behaviour. The heterogeneous catalysts lead to similar or higher alkene conversion than the homogeneous catalyst. DFT confirmed distortion of the complex in a confined space.

    8. Silylene Cycloaddition Products

      Reaction of the Silylene PhC(NtBu)2SitBu with 4,4′-Bis(dimethylamino)thiobenzophenone and Treatment of the Silylene PhC(NtBu)2SiC(SiMe3)3 with 3,5-Di-tert-butyl-o-benzoquinone (pages 2777–2781)

The compounds were structurally characterized by spectroscopic methods, X-ray crystallography, and voltammetric techniques.

    11. Si–B Bond Activation

      On the Reactivity of Silylboranes toward Lewis Bases: Heterolytic B–Si Cleavage vs. Adduct Formation (pages 2799–2806)

      Christian Kleeberg and Corinna Borner

      Article first published online: 5 APR 2013 | DOI: 10.1002/ejic.201300119

      Thumbnail image of graphical abstract

      The reaction of a Lewis base with a silylborane is central to a series of Lewis base-mediated reactions of silylboranes. For [K(18-C-6)OtBu] and an NHC the reaction products were isolated and characterized. Either the activation of a B–Si bond or the formation of Lewis acid/base adducts is observed. The reactivity of the reaction products toward selected electrophiles is studied.

      Heterobimetallic rare earth–alkali metal binaphtholates (REMBs) are exquisite catalysts for asymmetric synthesis. No REMBs with fewer than three binaphtholates have yet been characterized in the solid state. We report the first X-ray structure analyses of REMBs with only two, and even one, chiral ligands.

    13. Carbon Nanotubes

      Functionalized Carbon Nanotubes with Self-Templating Assembly Behavior (pages 2812–2816)

      Youan Lei and Lingzhi Du

      Article first published online: 5 APR 2013 | DOI: 10.1002/ejic.201201513

      Thumbnail image of graphical abstract

      Surface-functionalized carbon nanotubes (CNTs) with 100 % organic coverage exhibit parallel-aligned arrays with a tube distance of 26 nm in the absence of other templates. The alignment depends on the nature of the hydrophobic interaction between near-neighbor tubes. The depth of the perpendicular coating of the polysiloxane quaternary ammonium compound on the CNT surface is ca. 3.2 nm (inset).

    14. Solid-State Structures

      Growth and Characterization of Centimeter-Sized Ba2LaFeNb4O15 Crystals from High-Temperature Solution under a Controlled Atmosphere (pages 2817–2825)

      Article first published online: 9 APR 2013 | DOI: 10.1002/ejic.201300008

      Thumbnail image of graphical abstract

      Centimeter-sized Ba2LaFeNb4O15 (BLFNO) crystals are obtained by a flux method. A frequency-dependent dielectric permittivity maximum is found (Tm = 100 K at 5 kHz), which indicates relaxor behavior. Single-crystal XRD analysis reveals an incommensurate structure at room temperature with a bidimensional modulation characterized by vectors q1 = (α, α, 1/2) and q2 = (α, –α, 1/2) with α = 0.295(1).
