  1. Dual Gold-Catalyzed Head-to-Tail Coupling of Iodoalkynes

    M. Sc. Steffen Mader, Dr. Lise Molinari, Dr. Matthias Rudolph, Dr. Frank Rominger  and Prof. Dr. A. Stephen K. Hashmi 

    Article first published online: 23 JAN 2015 | DOI: 10.1002/chem.201406594

    Various haloalkynes are converted in the presence of a dual-activation gold catalyst. Through a dual activation process, a completely atom-economic head-to-tail coupling delivers gem- dihalogenated conjugated enynes as valuable building blocks for organic synthesis.

  2. Dinuclear Ruthenium(II) Complexes That Induce and Stabilise G-Quadruplex DNA

    Dr. Li Xu, Xiang Chen, Jingheng Wu, Jinquan Wang, Prof. Liangnian Ji and Prof. Dr. Hui Chao

    Article first published online: 23 JAN 2015 | DOI: 10.1002/chem.201405991

    Being blocked by Ru: A series of dinuclear ruthenium(II) complexes (see figure) were found to promote high stabilisation of the G-quadruplexes of human telomeric DNA and exhibited a high telomerase inhibiting activity.

  3. Highly Fluorinated Tris(indazolyl)borate Silylamido Complexes of the Heavier Alkaline Earth Metals: Synthesis, Characterization, and Efficient Catalytic Intramolecular Hydroamination

    Nuria Romero, Sorin-Claudiu Roşca, Dr. Yann Sarazin, Prof. Jean-François Carpentier, Dr. Laure Vendier, Sonia Mallet-Ladeira, Dr. Chiara Dinoi and Prof. Michel Etienne

    Stabilized distortion: The highly fluorinated 3-phenyl hydrotris(indazolyl)borate ligand {F12-Tp4Bo, 3Ph} coordinates the Ca and Sr metals to afford the heteroleptic silylamido derivatives [(F12-Tp4Bo, 3Ph)Ae{N(SiMe2R)2}] (Alkaline earth metal (Ae)=Ca, Sr, R=Me; Ae=Ca, R=H). Agostic distortions, which are especially strong for Sr, stabilize the structures (see figure). The complexes containing the {N(SiMe3)2} ligand catalyze the cyclohydroamination of aminoalkenes. The synthesis of the new homoleptic unsolvated [Ca{N(SiMe2H)2}2] precursor is also described.

  4. Natural Abundance 15N NMR by Dynamic Nuclear Polarization: Fast Analysis of Binding Sites of a Novel Amine-Carboxyl-Linked Immobilized Dirhodium Catalyst

    Enhanced applicability of15N NMR: Natural abundance 15N solid-state dynamic nuclear polarization (DNP) NMR is demonstrated as a powerful tool for analyzing nitrogen-containing binding sites in a novel heterogeneous dirhodium catalyst based on mesoporous silica (see graphic). This catalyst is demonstrated to be efficient in a cyclopropanation reaction.

  5. Broad Hexagonal Columnar Mesophases Formation in Bioinspired Transition-Metal Complexes of Simple Fatty Acid meta-Octaester Derivatives of meso-Tetraphenyl Porphyrins

    Dr. Bin Wu, Keyang Chen, Yuchen Deng, Jian Chen, Dr. Chengjie Liu, Prof. Rongshi Cheng and Prof.Dr. Dongzhong Chen

    Article first published online: 23 JAN 2015 | DOI: 10.1002/chem.201404708

    Thumbnail image of graphical abstract

    Metalloporphyrin liquid crystals: Well-organized hexagonal columnar mesophases of broad temperature ranges have been achieved in metal complexes of easily available fatty acid octaester substituted porphyrins. The liquid crystallinity of the free base and the metal porphyrins can be tuned with variant length side-chain substituents and different coordinated metal ions (see figure).
