  • The Stepwise Reaction of Rhodium and Iridium Complexes of Formula [MCl24C,N,N′,P−L)] with Silver Cations: A Case of trans-Influence and Chiral Self-Recognition
  • The Stepwise Reaction of Rhodium and Iridium Complexes of Formula [MCl2(κ4C,N,N′,P−L)] with Silver Cations: A Case of trans-Influence and Chiral Self-Recognition

    Let's go step by step: The chlorido ligands in complexes [MCl24C,N,N′,PL)] (M=Rh, Ir) were sequentially removed to give bis-solvato complexes of formula [M(κ4C,N,N′,PL)(NCMe)2]2+. The involved mono-, di- and trimetallic intermediates were isolated and characterized. The formation of these intermediates takes place with chiral self-recognition. The stereochemistry determined for the new species is compatible with the retention of the configuration of the metallic fragments throughout the whole process.

  • Alkali Metal Cation Affinities of Anionic Main Group-Element Hydrides Across the Periodic Table
  • Alkali Metal Cation Affinities of Anionic Main Group-Element Hydrides Across the Periodic Table

    Diffuse and Different! We have explored and analyzed Alkali Metal Cation Affinities (AMCA) of archetypal anionic bases with electrophilic centers across the periodic table. AMCAs are significantly weaker and show a number of different trends if compared to the corresponding proton affinities (PAs). Our bonding analyses trace the differences to the more diffuse nature and higher energy of the alkali cation ns LUMO as compared to the proton 1s LUMO.

  • A C(sp2)−H Dehydrogenation of Heteroarenes and Arenes by a Functionalized Aluminum Hydride
  • A C(sp2)−H Dehydrogenation of Heteroarenes and Arenes by a Functionalized Aluminum Hydride

    A functionalized aluminum hydride (2-TMP-C6H4)AlH2 has been prepared. The inherent N/Al donor/acceptor pair cooperatively activates the C(sp2)−H bond, which improves the aluminum hydride reactivity by the elusive C(sp2)−H dehydroalumination of N-heteroarenes and multiple-bond-containing arenes. These reactions open a straightforward route to heteroaryl and unique heterocyclic aluminum compounds.

  • The Thermodynamic Effects of Ligand Structure on the Molecular Recognition of Mono- and Biruthenium Polypyridyl Complexes with G-Quadruplex DNA

    Models of ΛΛ-44+, Λ-32+, and Λ-22+ (top bound) and ΔΔ-44+, Δ-32+, and Δ-22+ (bottom bound) are shown in a complex with c-MYC 1-2-1 G-quadruplex forming oligonucleotide construct. The tatpp moiety in 44+ or 32+ is capable of DNA double strand scission in the hypoxic environment of tumor cells. Compounds 44+ and 32+ have shown activity against non-small lung cell tumors in mouse models.

  • Monitoring Photosynthetic Activity in Microalgal Cells by Raman Spectroscopy with Deuterium Oxide as a Tracking Probe

    Photo finish: A method to monitor the photosynthetic activity of microalgae at single-cell resolution by Raman spectroscopy with deuterium from D2O as a tracking probe is presented. We use the probe to monitor the kinetics of C−D bond formation in E. gracilis cells and demonstrate the Raman microscopy imaging of each cell to discriminate deuterated from normal cells.

  • Facile Deboronation of Some o-Carboranylamides
  • Facile Deboronation of Some o-Carboranylamides

    Carboranylamide 1,2-(PhNHCO)2-o-C2B10H10 (3) in diethyl ether undergoes gradual deboronation leading to [PhNH3][7,8-(PhNHCO)2-nido-C2B9H10] (4). Further evidence shows that such closo-carboranylamides in certain solvents tend to undergo facile deboronation, depending on the number of amide groups and the nature of the solvents.

  • Synthesis of 10-Methylsulfide and 10-Alkylmethylsulfonium nido-Carborane Derivatives: B–H···π Interactions between the B–H–B Hydrogen Atom and Alkyne Group in 10-RC≡CCH2S(Me)-7,8-C2B9H11
  • Synthesis of 10-Methylsulfide and 10-Alkylmethylsulfonium nido-Carborane Derivatives: B–H···π Interactions between the B–H–B Hydrogen Atom and Alkyne Group in 10-RC≡CCH2S(Me)-7,8-C2B9H11

    Reaction of the protonated nido-carborane with SMe2 gives the 10-dimethylsulfonium derivative 10-Me2S-7,8-C2B9H11. Its demethylation-alkylation produces a series of 10-alkylmethylsulfonium derivatives 10-R(Me)S-7,8-C2B9H11. The compounds containing an alkyne group (R = CH2C≡CH, CH2C≡CPh, CH2C≡CSiMe3) demonstrate strong intramolecular B–H···π(C≡C) interactions both in the solid state and in solution.

  • Amorphous Transition Metal Sulfides Anchored on Amorphous Carbon-Coated Multiwalled Carbon Nanotubes for Enhanced Lithium-Ion Storage

    Hybrid power: Amorphous metal sulfides, anchored on carbon-coated carbon nanotubes, are designed and fabricated through a facile and effective procedure. Such amorphous structures of CoS2 and MoS2, adhered to CNTs@C, which hinders the agglomeration of CoS2 and MoS2, are beneficial for improving the electrochemical performance of the electrodes.

  • Alkynylation of Bio-Based 5-Hydroxymethylfurfural to Connect Biomass Processing with Conjugated Polymers and Furanic Pharmaceuticals

    Providing a platform: Acetylene-functionalized platform chemicals were synthesized from biomass-derived 5-hydroxymethylfurfural in high yields (89–99 %). The alkynylation process and the ethynylfuran derivatives obtained significantly extend the applicability of biomass-derived HMF as a platform chemical in fine organic synthesis, connecting biomass processing with furanic pharmaceuticals and conjugated polymers.

  • Catalytic Conversion of Dinitrogen into Ammonia under Ambient Reaction Conditions by Using Proton Source from Water

    A top model: Molybdenum-catalyzed conversion of molecular dinitrogen into ammonia under ambient reaction conditions has been achieved by using a proton source generated in situ from the ruthenium-catalyzed oxidation of water in combination with visible light and a photosensitizer. The present reaction system is considered as a new model for the nitrogen fixation by photosynthetic bacteria.
