AbstractDifferent metal precursors and reducing agents were applied in the preparation of 1 wt % Pd catalysts supported on commercial ion‐exchange resin (Lewatit K2621) and used in the direct synthesis of H2O2. The catalysts were characterized by using TEM and their performance was evaluated in the direct synthesis of H2O2 (in a batch and semi‐batch reactor) to investigate the relationship between the catalyst preparation methods, morphology, and catalytic performance. As expected, both the choice of the Pd precursor and the reduction conditions had a strong influence on the size and size distribution of the resulting supported nanostructured metal nanoparticles and, consequently, on the catalytic performance. The best combination of metal precursor and reduction agent was [Pd(NH3)4]SO4 reduced with hydrogen. This catalyst had the largest average size of the Pd nanoparticles and the broadest size distribution.
Oxime‐Derived Palladacycles: Applications in Catalysis
Authors: Nájera Carmen 
Published: April 2016

AbstractPhenone oxime‐derived palladacycles are stable, easy to prepare, and an excellent source of three‐ and four‐atom Pd clusters able to show excellent catalytic activity in most of the classical carbon–carbon bond forming reactions (Mizoroki–Heck, Matsuda–Heck, Suzuki–Miyaura, Stille, Kumada, Hiyama, Ullmann, Sonogashira, and Glasser), generally with better performance than Pd(OAc)2 or other Pd salts. Aryl iodides, bromides, chlorides, and imidazolyl sulfonates can be used as substrates not only in organic solvents but also in aqueous solvents including neat water. Appropriate choice of the general reaction conditions allow these C−C bond forming reactions to be performed efficiently. These palladacycles have been also used in carbonylations, several types of annulations, ketone arylations, C−H activation, oxime rearrangements, and behave as metalloenzymes in hydrolytic processes, among others. Not only dimer complexes can be used, but also monomer ones with an additional ligand as well as those supported on polymers, silica, and bearing ionic or fluorinated tags.
Evaluation of Chemical Diversity of Biotinylated Chiral 1,3‐Diamines as a Catalytic Moiety in Artificial Imine Reductase
Authors: Pellizzoni Michela , Facchetti Giorgio , Gandolfi Raffaella , Fusè Marco , Contini Alessandro , Rimoldi Isabella 
Published: April 2016

AbstractThe possibility of obtaining an efficient artificial imine reductase was investigated by introducing a chiral cofactor into artificial metalloenzymes based on biotin–streptavidin technology. In particular, a chiral biotinylated 1,3‐diamine ligand in coordination with iridium(III) complex was developed. Optimized chemogenetic studies afforded positive results in the stereoselective reduction of a cyclic imine, the salsolidine precursor, as a standard substrate with access to both enantiomers. Various factors such as pH, temperature, number of binding sites, and steric hindrance of the catalytic moiety have been proved to affect both efficiency and enantioselectivity, underlining the great flexibility of this system in comparison with the achiral system. Computational studies were also performed to explain how the metal configuration, in the proposed system, might affect the observed stereochemical outcome.
Biomineralization‐Inspired Preparation of Zinc Hydroxide Carbonate/Polymer Hybrids and Their Conversion into Zinc Oxide Thin‐Film Photocatalysts

Published: April 2016

AbstractThe development of ZnO thin films has been achieved through the conversion of zinc hydroxide carbonate thin‐film crystals. Crystallization of this compound is induced by a biomineralization‐inspired method with polymer‐stabilized amorphous precursors. The crystals grow radially on polymer matrices, leading to the formation of zinc hydroxide carbonate/polymer thin‐film hybrids that fully cover the substrate. These hybrids are converted into ZnO and retain their thin‐film morphologies. The resultant ZnO thin films exhibit a preferential crystallographic orientation that is attributed to the alignment of zinc hydroxide carbonate crystals before conversion. In addition, a photocatalytic function of the ZnO thin films has been demonstrated by analyzing the oxidation reaction of 2‐propanol. The biomineralization‐inspired approach reported herein is a promising way to develop ZnO materials with controlled morphologies and structures for photocatalytic applications.
Ferrocene‐Substituted Naphthalenediimide with Broad Absorption and Electron‐Transport Properties in the Segregated‐Stack Structure
Authors: Takai Atsuro , Sakamaki Daisuke , Seki Shu , Matsushita Yoshitaka , Takeuchi Masayuki 
Published: April 2016

AbstractA new naphthalenediimide (NDI) molecule, where two ferrocene (Fc) units were directly attached to both imide nitrogens (Fc‐NDI‐Fc), was synthesized. The Fc units provide high crystallinity to Fc‐NDI‐Fc with good solubility to conventional organic solvents. The Fc units also work as electron‐donating substituents, in contrast to the electron‐deficient NDI unit, resulting in broad charge‐transfer absorption of Fc‐NDI‐Fc from the UV region to 1500 nm in the solid state. The crystal structure analysis revealed that Fc‐NDI‐Fc formed a segregated‐stack structure. The DFT calculation based on the crystal structure showed that the NDI π‐orbitals extended over two axes. The extended π‐network of the NDI units led to the electron‐transport properties of Fc‐NDI‐Fc, which was confirmed using a flash‐photolysis time‐resolved microwave conductivity technique.
Carbon‐Nanotube‐Mediated Electrochemical Transition in a Redox‐Active Supramolecular Hydrogel Derived from Viologen and an l‐Alanine‐Based Amphiphile
Authors: Datta Sougata , Bhattacharya Santanu 
Published: April 2016

AbstractA two‐component hydrogelator (16‐A)2‐V2+, comprising an l‐alanine‐based amphiphile (16‐A) and a redox‐active viologen based partner (V2+), is reported. The formation the hydrogel depended, not only on the acid‐to‐amine stoichiometric ratio, but on the choice of the l‐amino acid group and also on the hydrocarbon chain length of the amphiphilic component. The redox responsive property and the electrochemical behavior of this two‐component system were further examined by step‐wise chemical and electrochemical reduction of the viologen nucleus (V2+/V+ and V+/V0). The half‐wave reduction potentials (E1/2) associated with the viologen ring shifted to more negative values with increasing amine component. This indicates that higher extent of salt formation hinders reduction of the viologen moiety. Interestingly, the incorporation of single‐walled carbon nanotubes in the electrochemically irreversible hydrogel (16‐A)2‐V2+ transformed it into a quasi‐reversible electrochemical system.

Published: April 2016

AbstractEnergetic materials (explosives, propellants, and pyrotechnics) are used extensively for both civilian and military applications and the development of such materials, particularly in the case of energetic salts, is subject to continuous research efforts all over the world. This Review concerns recent advances in the syntheses, properties, and potential applications of ionic salts based on tetrazole N‐oxide. Most of these salts exhibit excellent characteristics and can be classified as a new family of highly energetic materials with increased density and performance, alongside decreased mechanical sensitivity. Additionally, novel tetrazole N‐oxide salts are proposed based on a diverse array of functional groups and ions pairs, which may be promising candidates for new energetic materials.
Unusual NHC–Iridium(I) Complexes and Their Use in the Intramolecular Hydroamination of Unactivated Aminoalkenes

Published: April 2016

AbstractN‐heterocyclic carbene (NHC) ligands with naphthyl side chains were employed for the synthesis of unsaturated, yet isolable [(NHC)Ir(cod)]+ (cod=1,5‐cyclooctadiene) complexes. These compounds are stabilised by an interaction of the aromatic wingtip that leads to a sideways tilt of the NHC−Ir bond. Detailed studies show how the tilting of such N‐heterocyclic carbenes affects the electronic shielding properties of the carbene carbon atom and how this is reflected by significant upfield shifts in the 13C NMR signals. When employed in the intramolecular hydroamination, these [(NHC)Ir(cod)]+ species show very high catalytic activity under mild reaction conditions. An enantiopure version of the catalyst system produces pyrrolidines with excellent enantioselectivities.
Host–Guest Chemistry: Oxoanion Recognition Based on Combined Charge‐Assisted C−H or Halogen‐Bonding Interactions and Anion⋅⋅⋅Anion Interactions Mediated by Hydrogen Bonds

Published: April 2016

AbstractSeveral bis‐triazolium‐based receptors have been synthesized and their anion‐recognition capabilities have been studied. The central chiral 1,1′‐bi‐2‐naphthol (BINOL) core features either two aryl or ferrocenyl end‐capped side arms with central halogen‐ or hydrogen‐bonding triazolium receptors. NMR spectroscopic data indicate the simultaneous occurrence of several charge‐assisted aliphatic and heteroaromatic C−H noncovalent interactions and combinations of C−H hydrogen and halogen bonding. The receptors are able to selectively interact with HP2O73−, H2PO4−, and SO42− anions, and the value of the association constant follows the sequence: HP2O73−>SO42−>H2PO4−. The ferrocenyl end‐capped 72+⋅2 BF4− receptor allows recognition and differentiation of H2PO4− and HP2O73− anions by using different channels: H2PO4− is selectively detected through absorption and emission methods and HP2O73− by using electrochemical techniques. Significant structural results are the observation of an anion⋅⋅⋅anion interaction in the solid state (2:2 complex, 62+⋅[H2P2O7]2−), and a short C−I⋅⋅⋅O contact is observed in the structure of the complex [82+][SO4]0.5[BF4].
Synthesis, Structure, and Molecular Recognition of S6‐ and (SO2)6‐Corona[6](het)arenes: Control of Macrocyclic Conformation and Properties by the Oxidation State of the Bridging Heteroatoms
Authors: Guo Qing‐Hui , Zhao Liang , Wang Mei‐Xiang 
Published: April 2016

AbstractWe report herein the synthesis, structure, and molecular recognition of S6‐ and (SO2)6‐corona[6](het)arenes, and demonstrate a unique and efficient strategy of regulating macrocyclic conformation and properties by adjusting the oxidation state of the heteroatom linkages. The one‐pot nucleophilic aromatic substitution reaction of 1,4‐benzenedithiol derivatives, biphenyl‐4,4′‐dithiol and 9,9‐dipropyl‐9H‐fluorene‐2,7‐dithiol with 3,6‐dichlorotetrazine afforded S6‐corona[3]arene[3]tetrazines. These compounds underwent inverse‐electron‐demand Diels–Alder reaction with enamines and norbornadiene to produce S6‐corona[3]arene[3]pyridazines. Facile oxidation of sulfide linkages yielded (SO2)6‐corona[3]arene[3]pyridazines. All corona[6](het)arenes adopted generally hexagonal macrocyclic ring structures; however, their electronic properties and conformation could be fine‐tuned by altering the oxidation state of the sulfur linkages. Whereas (SO2)6‐corona[3]arene[3]pyridazines were electron‐deficient, S6‐corona[3]arene[3]pyridazines acted as electron‐rich macrocyclic hosts that recognized various organic cations in both aqueous and organic solutions.
Fluorescent Cross‐Linked Supramolecular Polymer Constructed by Orthogonal Self‐Assembly of Metal–Ligand Coordination and Host–Guest Interaction

Published: April 2016

AbstractA new host molecule consists of four terpyridine groups as the binding sites with zinc(II) ion and a copillar[5]arene incorporated in the center as a spacer to interact with guest molecule was designed and synthesized. Due to the 120 ° angle of the rigid aromatic segment, a cross‐linked dimeric hexagonal supramolecular polymer was therefore generated as the result of the orthogonal self‐assembly of metal–ligand coordination and host–guest interaction. UV/Vis spectroscopy, 1H NMR spectroscopy, viscosity and dynamic light‐scattering techniques were employed to characterize and understand the cross‐linking process with the introduction of zinc(II) ion and guest molecule. More importantly, well‐defined morphology of the self‐assembled supramolecular structure can be tuned by altering the adding sequence of the two components, that is, the zinc(II) ion and the guest molecule. In addition, introduction of a competitive ligand suggested the dynamic nature of the supramolecular structure.

AbstractA series of one‐pot, sequential protocols was developed for the synthesis of novel macrocycles bearing α,β‐unsaturated chemotypes. The method highlights a phosphate tether‐mediated approach to establish asymmetry, and consecutive one‐pot, sequential processes to access the macrocycles with minimal purification procedures. This library amenable strategy provided diverse macrocycles containing α,β‐unsaturated carbon‐, sulfur‐, or phosphorus‐based warheads.
Ultrathin Coating of Confined Pt Nanocatalysts by Atomic Layer Deposition for Enhanced Catalytic Performance in Hydrogenation Reactions

Published: April 2016

AbstractMetal‐support interfaces play a prominent role in heterogeneous catalysis. However, tailoring the metal‐support interfaces to realize full utilization remains a major challenge. In this work, we propose a graceful strategy to maximize the metal‐oxide interfaces by coating confined nanoparticles with an ultrathin oxide layer. This is achieved by sequential deposition of ultrathin Al2O3 coats, Pt, and a thick Al2O3 layer on carbon nanocoils templates by atomic layer deposition (ALD), followed by removal of the templates. Compared with the Pt catalysts confined in Al2O3 nanotubes without the ultrathin coats, the ultrathin coated samples have larger Pt–Al2O3 interfaces. The maximized interfaces significantly improve the activity and the protecting Al2O3 nanotubes retain the stability for hydrogenation reactions of 4‐nitrophenol. We believe that applying ALD ultrathin coats on confined catalysts is a promising way to achieve enhanced performance for other catalysts.
