Hot Paper: Cooperative Bond Activation and Catalytic Reduction of Carbon Dioxide at a Group 13 Metal Center

Joseph A. B. Abdalla, Dr. Ian M. Riddlestone, Rémi Tirfoin and Prof. Simon Aldridge

Cooperative Bond Activation and Catalytic Reduction of Carbon Dioxide at a Group 13 Metal CenterA single-component ambiphilic Group 13 system has been developed, capable of the cooperative activation of protic, hydridic and apolar H[BOND]X bonds. The hydride complex derived from the activation of H2 catalyzes the selective transformation of CO2 to a methanol derivative, representing the first example of such a reduction process catalyzed by a molecular gallium complex.

On the Role of the Electronic Structure of the Heteronuclear Oxide Cluster [Ga2Mg2O5].+ in the Thermal Activation of Methane and Ethane: An Unusual Doping EffectBridging oxygen: A combination of mass spectrometry and quantum chemical calculations shows that [Ga2Mg2O5].+, bearing an unpaired electron at a bridging oxygen atom, is capable of activating the C[BOND]H bond of methane. The roles of spin density and charge distributions in hydrogen-atom transfer processes provide important guidance for the rational design of catalysts.

Hot Paper: Lewis Acid Promoted Ruthenium(II)-Catalyzed Etherifications by Selective Hydrogenation of Carboxylic Acids/Esters

Dr. Yuehui Li, Dr. Christoph Topf, Dr. Xinjiang Cui, Dr. Kathrin Junge and Prof. Dr. Matthias Beller

Lewis Acid Promoted Ruthenium(II)-Catalyzed Etherifications by Selective Hydrogenation of Carboxylic Acids/EstersAn assist from Al: A bifunctional catalyst system consisting of a Ru/phosphine complex and aluminum triflate allows selective hydrogenation of esters to ethers. A variety of lactones were reduced to the desired products in good yields. The catalyst further provides a general method for the reduction of linear esters and reductive etherification of carboxylic acids with alcohols.

VIP: Oxidative Addition of Carbon–Carbon Bonds to Gold

Dr. Maximilian Joost, Dr. Laura Estévez, Dr. Karinne Miqueu, Dr. Abderrahmane Amgoune and Dr. Didier Bourissou

Oxidative Addition of Carbon–Carbon Bonds to GoldGold(I) complexes ([(DPCb)Au]+) readily insert into the four-membered rings of biphenylene and benzocyclobutenone. These transformations afforded well-defined cationic organogold(III) complexes that were isolated and fully characterized. [(DPCb)Au]+ is the only complex to cleave selectively either the C(aryl)[BOND]C(O) or the C(alkyl)[BOND]C(O) bond of benzocyclobutenone under kinetic/thermodynamic control. DPCb=diphosphinocarborane.

VIP: Well-Defined CuC2F5 Complexes and Pentafluoroethylation of Acid Chlorides

Liubov I. Panferova, Fedor M. Miloserdov, Dr. Anton Lishchynskyi, Dr. Marta Martínez Belmonte, Dr. Jordi Benet-Buchholz and Prof. Vladimir V. Grushin

Well-Defined CuC2F5 Complexes and Pentafluoroethylation of Acid ChloridesFour well-defined CuC2F5 complexes have been prepared and fully characterized, with [(phen)Cu(PPh3)C2F5] (phen=1,10-phenanthroline) proving to be a remarkably efficient fluoroalkylating agent for a broad variety of acid chlorides (see scheme). The developed procedure represents the first general method for the one-step conversion of RCOCl into valuable pentafluoroethyl ketones.

VIP: Synthesis of Carbon/Sulfur Nanolaminates by Electrochemical Extraction of Titanium from Ti2SC

Dr. Meng-Qiang Zhao, Morgane Sedran, Zheng Ling, Maria R. Lukatskaya, Olha Mashtalir, Michael Ghidiu, Boris Dyatkin, Darin J. Tallman, Prof. Thierry Djenizian, Prof. Michel W. Barsoum and Prof. Yury Gogotsi

Synthesis of Carbon/Sulfur Nanolaminates by Electrochemical Extraction of Titanium from Ti2SCCarbon/sulfur nanolaminates composed of multi-layered C/S flakes with predominantly amorphous, and some graphene-like, structures were synthesized by electrochemical extraction of Ti from a Ti2SC MAX phase. This approach provides a novel method for the room-temperature synthesis of “AX” layered structures by the selective extraction of “M” from the MAX phases.

Hot Paper: Iron-Catalyzed Dehydropolymerization: A Convenient Route to Poly(phosphinoboranes) with Molecular-Weight Control

Dr. André Schäfer, Dr. Titel Jurca, Joshua Turner, Dr. James R. Vance, Dr. Kajin Lee, Dr. Van An Du, Dr. Mairi F. Haddow, Dr. George R. Whittell and Prof. Dr. Ian Manners

Iron-Catalyzed Dehydropolymerization: A Convenient Route to Poly(phosphinoboranes) with Molecular-Weight ControlLoading matters: The catalyst loading is the key to control the molecular weight of the polymer in the iron-catalyzed dehydropolymerization of phosphine–borane adducts. Studies showed that the reaction proceeds through a chain-growth coordination–insertion mechanism.

Hot Paper: Visible-Light-Triggered Molecular Photoswitch Based on Reversible E/Z Isomerization of a 1,2-Dicyanoethene Derivative

Dr. Xin Guo, Jiawang Zhou, Dr. Maxime A. Siegler, Prof. Dr. Arthur E. Bragg and Prof. Dr. Howard E. Katz

Visible-Light-Triggered Molecular Photoswitch Based on Reversible E/Z Isomerization of a 1,2-Dicyanoethene DerivativeLight switch: A dicyanoethene-based molecular photoswitch operates only through E/Z photoisomerization that is triggered by visible light (100 % E[RIGHTWARDS ARROW]Z conversion within minutes). The combination of favorable properties in a single photochromic switch makes it an attractive alternative to the frequently used azobenzenes in numerous photoswitching applications.
