      The reaction of diazo derivatives with olefins represents a valid tool to synthesise cyclopropanes. Rhodium and cobalt porphyrin complexes have been extensively employed as catalysts, and in several cases outstanding stereocontrol has been achieved. Recent advances in understanding the reaction mechanism will be crucial to plan new and more efficient catalytic systems.

      The thermal stability of hexatitanate nanowires produced by hydrothermal digestion of TiO2 in concentrated KOH solution followed by ion exchange depends acutely on their composition. Depending on the mix of cations present, behavior can range from rapid conversion to anatase, retarded conversion to anatase or recrystallization of a mixed-cation titanate.

    2. Recyclable Photocatalyst

      A Facile Approach for the Synthesis of Ag-Coated Fe3O4@TiO2 Core/Shell Microspheres as Highly Efficient and Recyclable Photocatalysts (pages 5096–5104)

      Version of Record online: 11 OCT 2011 | DOI: 10.1002/ejic.201100707

      Thumbnail image of graphical abstract

      Ag-coated Fe3O4@TiO2 microspheres with a very good core/shell structure, show excellent magnetic properties at room temperature. The formation of a Ag–TiO2heterojunction results in good photodegradation properties of the products. The results show that the as-prepared composites can be used as convenient and recyclable photocatalysts.

    3. Oxothiometalates

      Direct Synthesis and Mass Spectroscopic Observation of the {M40} Polyoxothiometalate Wheel (pages 5105–5111)

      Thumbnail image of graphical abstract

      A direct synthesis giving improved yields as well as detailed solution and solid-state characterisation of the oxothiometalate {Mo40} wheel is reported. High resolution ESI-MS studies allowed the direct observation of the discrete wheel and its assembly stages towards the 1D chain formation.

    4. Helical Metal Complexes

      Helical Complexes of Chiral Quaterpyridines – Mononuclear CuII and Dinuclear CuI Complexes (pages 5112–5124)

      Ho-Lun Yeung, Kiu-Chor Sham, Wai-Yeung Wong, Chun-Yuen Wong and Hoi-Lun Kwong

      Version of Record online: 12 OCT 2011 | DOI: 10.1002/ejic.201100630

      Thumbnail image of graphical abstract

      Bi- and mononuclear chiral helical copper–quaterpyridine complexes were prepared by treating chiral ligands like L3 with CuI and CuII precursors. They were studied by ESI-MS, elemental analysis, and CD spectroscopy. Solution-NMR studies of the dinuclear CuI complexes show that each sample consists of two diastereomers with moderate to high diastereoselectivity (52–99 %).

    5. Hybrid Metal Oxides

      Can Hydrophobic Interactions Influence Supramolecular Aggregation in Self-Assembled Organic–Inorganic Hybrid Structures? (pages 5125–5131)

      Kirsten Heussner, Mathias Grabau, Johannes Forster and Carsten Streb

      Version of Record online: 21 OCT 2011 | DOI: 10.1002/ejic.201100676

      Thumbnail image of graphical abstract

      The ability of amphiphilic cations to control the assembly of hybrid organic-inorganic frameworks through hydrophobic interactions was evaluated using a polyoxometalate-based model system. It is shownthat the formation of hydrophobic regions seems to be dependent on the size of the inorganic building block used. The structural analysis is further substantiated by theoretical Hirshfeld analysis.

    6. Diruthenium Complexes

      Cyano- and Aqua-Coordinated Diruthenium(III) Complexes with Oxo-Bis(acetato) Bridge: Preparation and Steric and Electronic Structures (pages 5132–5143)

      Version of Record online: 21 OCT 2011 | DOI: 10.1002/ejic.201100724

      Thumbnail image of graphical abstract

      Two cyano- and one aqua-coordinated diruthenium(III) complexes with an oxo-bis(acetato) bridge have been isolated. The cyano ligand has a strong effect on the properties of complexes. MO calculations revealed that visible absorption bands of complexes without a cyano ligand are ascribed to the transitions within Ru(dπ)–μ-O(pπ) molecular orbitals, whereas those of cyano complexes are different.

    7. Hydrogen Polyoxides

      Synthesis of Hydrogen Polyoxides H2O4 and H2O3 and Their Characterization by Raman Spectroscopy (pages 5144–5150)

      Peroxy radical condensates have been synthesized from O2/H2 gas mixtures dissociated by a microwave discharge (pressure ca. 1 Torr). They consist of hydrogen tetroxide (H2O4, up to 20 mol-%) and hydrogen trioxide (H2O3, up to 30 mol-%), hydrogen peroxide, and water. The polyoxides have been characterized by vibrational Raman spectroscopy of their oxygen frameworks.

    8. Titanium Alkoxides

      Synthesis, Isolation and Structural Characterisation of Alkoxytitanium Triflate Complexes (pages 5151–5159)

      Matthew G. Davidson and Andrew L. Johnson

      Version of Record online: 19 OCT 2011 | DOI: 10.1002/ejic.201100830

      Thumbnail image of graphical abstract

      New alkoxytitanium triflate complexes containing a range of facially coordinating N3 ligands were prepared and structurally characterised. Reaction of [Ti(OiPr3)OTf] with 1,3,5-triphenyl-1,3,5-triazacyclohexane results in the catalytic activation of the triazacyclohexane ligands and isolation of a new titanium complex [{L′}2Ti(OiPr)2(OTf)2] (L′ = 3-phenyl-3,4-dihydroquinazoline).

    9. Metal Oxidation

      Metal Oxidation with N2O5: The Nitrosylium Nitrates (NO)Cu(NO3)3, (NO)2[Zn­(NO3)4] and (NO)6[Ni4(NO3)12](NO3)2·(HNO3) (pages 5160–5166)
