Cross‐Linked Thiazolidine Network as Support for Palladium: A New Catalyst for Suzuki and Heck Reactions
Authors: Bivona Lucia Anna , Giacalone Francesco , Vaccaro Luigi , Aprile Carmela , Gruttadauria Michelangelo 
Published: August 2015

AbstractA thiazolidine‐based material was used for the first time as support for palladium. The support was prepared by starting from a highly cross‐linked thiazolium‐based material, obtained by radical oligomerization of a bisvinylthiazolium dibromide salt in the presence of 3‐mercaptopropyl‐modified silica SBA‐15. Palladium was immobilized by treatment with tetrachloropalladate salt. Reduction with sodium borohydride afforded a thiazolidine‐based material that acted as ligands for the Pd species. The thiazolidine‐based palladium catalyst was fully characterized and, working in only 0.1 mol % amount, displayed good activity in the Suzuki–Miyaura and in the Heck reactions. Several biphenyl and alkene compounds could be prepared in high yields. The catalytic material proved to be fully recoverable and it was representatively used for three times in the Suzuki–Miyaura reaction without showing any decrease in its activity.

Published: August 2015

AbstractPolystyrene‐grafted silica nanoparticles bearing sulfonic acid centers and with tunable amphiphilic properties were designed to perform the biphasic etherification reaction of glycerol with dodecanol at the interface of Pickering emulsions. By optimizing the hydrophobic properties of the particles, double Pickering emulsions could be generated allowing a facilitated diffusion of glycerol and dodecanol into the microenvironment near the acid centers.
Mesoporous Titania‐Iron(III) Oxide with Nanoscale Porosity and High Catalytic Activity for the Synthesis of β‐Amino Alcohols and Benzimidazole Derivatives
Authors: Roy Susmita , Banerjee Biplab , Salam Noor , Bhaumik Asim , Islam Sk. Manirul 
Published: August 2015

AbstractA mesoporous TiO2‐Fe2O3 mixed oxide material (MTF‐1E) with nanoscale porosity and a high BET surface area was synthesized using sodium dodecyl sulfate (SDS) as a structure‐directing agent. The material was characterized by powder XRD, high‐resolution TEM, N2 sorption, and NH3 temperature‐programmed desorption studies. The catalyst shows an excellent regioselectivity for the ring‐opening of epoxides with amines under solvent‐free conditions at room temperature for the synthesis of a series of β‐amino alcohols. It also showed a very high catalytic efficiency for the synthesis of benzimidazole derivatives in water. The catalyst can be recovered easily from the reaction medium and reused six times without a significant decrease in its catalytic activity and selectivity.
High‐Temperature, In Situ X‐ray Absorption Study of Sr2MgMoO6 Solid‐Oxide Fuel‐Cell Anode Materials
Authors: Eigenbrodt Bryan C. , Young Anthony M. , Howell Thomas G. , Segre Carlo U. , Reitz Thomas L. 
Published: August 2015

AbstractLimitations of current solid oxide fuel cell anode materials have spurred the exploration of alternative materials. Mixed ionic and electronic conducting anode materials have the potential to overcome these limitations. The mixed ionic and electronic conducting material explored in this work is Sr2MgMoO6 (SMMO). X‐ray absorption spectroscopy in conjunction with an in situ assembly was used to study the fundamental redox chemistry of SMMO at 800 °C. The X‐ray absorption spectra for the Mo K‐edge exhibited changes in the reduced and oxidized bulk SMMO samples, as evident in a shift in the Mo binding energies and in the formation of oxide vacancies. However, in situ measurements of the working devices revealed that the Mo oxidation state remained unchanged under various cell polarizations. These findings demonstrate that SMMO, as a solid oxide fuel cell anode, has the potential to provide adequate electron conduction through multivalent Mo sites and to provide fuel tolerance through oxide vacancies built into its crystal structure.
Electrochemical Degradation of Multiwall Carbon Nanotubes at High Anodic Potential for Oxygen Evolution in Acidic Media

Published: August 2015

AbstractThere is great interest in electrochemical water splitting for the efficient utilization of sustainable energy. As an alternative to high‐priced materials, carbon offers considerable potential. However, carbon is limited as an electrode material for the oxygen evolution reaction (OER), owing to its thermodynamic instability against electrochemical oxidation. In this study, we investigated the electrochemical degradation of multiwall carbon nanotubes (MWCNTs) under the acidic OER environment. Electrochemical oxidation of MWCNTs induces structural changes and the formation of oxygen‐containing functional groups on the carbon surface. As a consequence, the electrochemical and physicochemical properties of the MWCNTs are changed during electrochemical oxidation. We carried out electrochemical, microstructural, and spectroscopic analysis to investigate the degradation of MWCNTs. By changing of the electrochemical properties of MWCNTs during the oxidation process, the carbon electrode is initially activated and can then be kinetically stabilized with prolonged oxidation under the OER conditions.
Molecular Mixed‐Metal Manganese Oxido Cubanes as Precursors to Heterogeneous Oxygen Evolution Catalysts
Authors: Suseno Sandy , McCrory Charles C. L. , Tran Rosalie , Gul Sheraz , Yano Junko , Agapie Theodor 
Published: August 2015

AbstractWell‐defined mixed‐metal [CoMn3O4] and [NiMn3O4] cubane complexes were synthesized and used as precursors for heterogeneous oxygen evolution reaction (OER) electrocatalysts. The discrete clusters were dropcasted onto glassy carbon (GC) and indium tin oxide (ITO) electrodes, and the OER activities of the resulting films were evaluated. The catalytic surfaces were analyzed by various techniques to gain insight into the structure‐function relationships of the electrocatalysts’ heterometallic composition. Depending on preparation conditions, the Co‐Mn oxide was found to change metal composition during catalysis, while the Ni–Mn oxides maintained the NiMn3 ratio. XAS studies provided structural insights indicating that the electrocatalysts are different from the molecular precursors, but that the original NiMn3O4 cubane‐like geometry was maintained in the absence of thermal treatment (2‐Ni). In contrast, the thermally generated 3‐Ni develops an oxide‐like extended structure. Both 2‐Ni and 3‐Ni undergo structural changes upon electrolysis, but they do not convert into the same material. The observed structural motifs in these heterogeneous electrocatalysts are reminiscent of the biological oxygen‐evolving complex in Photosystem II, including the MMn3O4 cubane moiety. The reported studies demonstrate the use of discrete heterometallic oxide clusters as precursors for heterogeneous water oxidation catalysts of novel composition and the distinct behavior of two sets of mixed metal oxides.
Efficient Syntheses of Novel Fluoro‐Substituted Pentacenes and Azapentacenes: Molecular and Solid‐State Properties
Authors: Schwaben Jonas , Münster Niels , Klues Michael , Breuer Tobias , Hofmann Philipp , Harms Klaus , Witte Gregor , Koert Ulrich 
Published: August 2015

AbstractNon‐symmetrical 6,13‐disubstituted pentacenes bearing trifluoromethyl and aryl substituents have been synthesized starting from pentacenequinone. Diazapentacenes with a variety of fluorine substituents were prepared either via a Hartwig–Buchwald aryl amination route or by a SNAr strategy. As a result of a non‐symmetric substitution pattern containing electron‐donating substituents in combination with electron‐accepting fluorine substituents, the synthesized compounds feature distinct molecular dipoles. All compounds are analyzed regarding their optoelectronic properties in solution with special focus on the frontier orbital energies as well as their molecular packing in the crystal structures. The analyses of isolated molecules are complemented by thin‐film studies to examine their solid‐state properties. A precise comparison between these and the molecular properties gave detailed insights into the exciton binding energies of these compounds, which are explained by means of a simple model considering the molecular packing and polarizabilities.

Published: August 2015

AbstractAzobenzene linker molecules can be utilized to control peptide/protein function when they are ligated to appropriately spaced amino acid side chains of the peptide. This is because the photochemical E/Z isomerization of the azobenzene NN double bond allows to switch peptide conformation between folded and unfolded. In this context, we have introduced carbohydrate‐functionalized azobenzene derivatives in order to advance the biocompatible properties of azobenzene peptide linkers. Chloroacetamide‐functionalized and O‐allylated carbohydrate derivatives were synthesized and conjugated with azobenzene to achieve new bifunctional cross‐linkers, in order to allow ligation to cysteine side chains by nucleophilic substitution or thiol‐ene reaction, respectively. The photochromic properties of the new linker glycoconjugates were determined and first ligation reactions performed.
Formal Gold‐to‐Gold Transmetalation of an Alkynyl Group Mediated by Palladium: A Bisalkynyl Gold Complex as a Ligand to Palladium

Published: August 2015

AbstractThe reaction of [Au(CCn‐Bu)]n with [Pd(η3‐allyl)Cl(PPh3)] results in a ligand and alkynyl rearrangement, and leads to the heterometallic complex [Pd(η3‐allyl){Au(CCn‐Bu)2}]2 (3) with an unprecedented bridging bisalkynyl–gold ligand coordinated to palladium. This is a formal gold‐to‐gold transmetalation that occurs through reversible alkynyl transmetalations between gold and palladium.

Authors: Khatri Hem Raj , Nguyen Hai , Dunaway James K. , Zhu Jianglong 
Published: August 2015

AbstractThe first total synthesis of derhodinosylurdamycin A, an angucycline antitumor antibiotic, has been described. The synthesis features a Hauser annulation followed by pinacol coupling to construct the tetracyclic angular aglycon, a Stille coupling of glycal stannane and tetracyclic aryliodide followed by stereoselective reduction to afford the 2‐deoxy β‐C‐arylglycoside, and a late‐stage stereoselective glycosylation for the preparation of derhodinosylurdamycin A. This synthetic strategy should be amenable to the chemical synthesis of analogs of derhodinosylurdamycin A bearing diverse 2‐deoxy sugar subunits for structure and activity relationship studies.
One‐Electron Oxidation of a Disilicon(0) Compound: An Experimental and Theoretical Study of [Si2]+ Trapped by N‐Heterocyclic Carbenes

Published: August 2015

AbstractOne‐electron oxidation of the disilicon(0) compound Si2(Idipp)2 (1, Idipp=1,3‐bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene) with [Fe(C5Me5)2][B(ArF)4] (ArF=C6H3‐3,5‐(CF3)2) affords selectively the green radical salt [Si2(Idipp)2][B(ArF)4] (1‐[B(ArF)4). Oxidation of the centrosymmetric 1 occurs reversibly at a low redox potential (E1/2=−1.250 V vs. Fc+/Fc), and is accompanied by considerable structural changes as shown by single‐crystal X‐ray structural analysis of 1‐B(ArF)4. These include a shortening of the SiSi bond, a widening of the Si‐Si‐CNHC angles, and a lowering of the symmetry, leading to a quite different conformation of the NHC substituents at the two inequivalent Si sites in 1+. Comparative quantum chemical calculations of 1 and 1+ indicate that electron ejection occurs from the symmetric (n+) combination of the Si lone pairs (HOMO). EPR studies of 1‐B(ArF)4 in frozen solution verified the inequivalency of the two Si sites observed in the solid‐state, and point in agreement with the theoretical results to an almost equal distribution of the spin density over the two Si atoms, leading to quite similar 29Si hyperfine coupling tensors in 1+. EPR studies of 1‐B(ArF)4 in liquid solution unraveled a topomerization with a low activation barrier that interconverts the two Si sites in 1+.
