Top‐Down and Bottom‐Up Approaches in Engineering 1 T Phase Molybdenum Disulfide (MoS2): Towards Highly Catalytically Active Materials
Chemistry - A European Journal - Tập 22 Số 40 - Trang 14336-14341 - 2016
Chun Kiang Chua, Adeline Huiling Loo, Martin Pumera
AbstractThe metallic 1 T phase of MoS2 has been widely identified to be responsible for the improved performances of MoS2 in applications including hydrogen evolution reactions and electrochemical supercapacitors. To this aim, various synthetic methods have been reported to obtain 1 T phase‐rich MoS2. H...... hiện toàn bộ
Ru‐Catalyzed Branched versus Linear Selective C3‐Alkylation of 2‐Aroylbenzofurans with Acrylates via CH Activation
Chemistry - A European Journal - Tập 20 Số 26 - Trang 7884-7889 - 2014
Yadagiri Kommagalla, Kolluru Srinivas, Chepuri V. Ramana
AbstractThe carbonyl‐directed C3H activation and alkylation of 2‐aroylbenzo[b]furans with acrylates occurs selectively either in a linear or branched fashion, depending on the catalyst employed; [Ru(p‐cymene)Cl2]2 or Ru(PPh3)3Cl...... hiện toàn bộ
Recent Advances in the Chemistry and Biology of Podophyllotoxins
Chemistry - A European Journal - Tập 23 Số 19 - Trang 4467-4526 - 2017
Yu Xiang, Zhiping Che, Hui Xu
AbstractPodophyllotoxin and its related aryltetralin cyclolignans belong to a family of important products that exhibit various biological properties (e.g., cytotoxic, insecticidal, antifungal, antiviral, anti‐inflammatory, neurotoxic, immunosuppressive, antirheumatic, antioxidative, antispasmogenic, and hypolipidemic activities). This Review provides a survey of p...... hiện toàn bộ
Ultrasensitive Electrochemical Analysis of Two Analytes by Using an Autonomous DNA Machine that Works in a Two‐Cycle Mode
Chemistry - A European Journal - Tập 17 Số 27 - Trang 7531-7537 - 2011
Hui Zhang, Congcong Fang, Shusheng Zhang
AbstractWe report a novel autonomous DNA machine for amplified electrochemical analysis of two DNAs. The DNA machine operates in a two‐cycle working mode to amplify DNA recognition events; the working mode is assisted by two different nicking endonucleases (NEases). Two bio‐barcode probes, a ZnS nanoparticle (NP)–DNA probe and a CdS NP–DNA probe, were used to trace...... hiện toàn bộ
Supramolecular Structure, Physical Properties, and Langmuir‐Blodgett Film Formation of an Optically Active Liquid‐Crystalline Phthalocyanine
Chemistry - A European Journal - Tập 1 Số 3 - Trang 171-182 - 1995
Cornelus F. van Nostrum, Anton W. Bosman, Gerwin H. Gelinck, Pieter G. Schouten, John M. Warman, Arno P. M. Kentgens, Marinus A. C. Devillers, Andries Meijerink, Stephen J. Picken, Ulrich Sohling, A. Schouten, Roeland J. M. Nolte
AbstractThe structure and physical properties of optically active, metal‐free 2,3,9,10,16,17,23,24‐octa (S‐3,7‐dimethyloctoxy)phthalocyanine ((S)‐Pc(8,2)) are reported and compared with those of the phthalocyanine with (R,S) side chains (mixture of 43 stereoi...... hiện toàn bộ
Palladium Nanoclusters Supported on Propylurea‐Modified Siliceous Mesocellular Foam for Coupling and Hydrogenation Reactions
Chemistry - A European Journal - Tập 14 Số 10 - Trang 3118-3125 - 2008
Nandanan Erathodiyil, Samuel Ooi, Abdul Majeed Seayad, Yu Han, Su Seong Lee, Jackie Y. Ying
AbstractThis paper describes the synthesis, characterization and applications of palladium (Pd) nanoparticles supported on siliceous mesocellular foam (MCF). Pd nanoparticles of 2–3 nm and 4–6 nm were used in reactions involving molecular hydrogen (such as hydrogenation of double bonds and reductive amination), transfer hydrogenation of ketones and epoxides, and co...... hiện toàn bộ
Memory Effect of Activated Mg–Al Hydrotalcite: In Situ XRD Studies during Decomposition and Gas‐Phase Reconstruction
Chemistry - A European Journal - Tập 13 Số 3 - Trang 870-878 - 2007
Javier Pérez‐Ramírez, Sònia Abelló, N. M. van der Pers
AbstractThe thermal decomposition of Mg–Al hydrotalcite and the subsequent reconstruction of the decomposed products in the presence of water vapor (2 vol. % H2O in N2) have been investigated by in situ XRD. Thermographic analysis and temperature‐programmed desorption MS results complemented the diffraction data. Valuable m...... hiện toàn bộ

Reinvestigation of the Noncatalyzed Coupling of Aryllithium with Haloarene: A Novel Aromatic Nucleophilic Substitution Pathway
Chemistry - A European Journal - Tập 9 Số 14 - Trang 3209-3215 - 2003
Jean‐Michel Becht, Arnaud Gissot, Alain Wagner, Charles Mioskowski
AbstractNoncatalyzed coupling reactions of aryllithiums and haloarenes proceed not only through the well‐known aryne route but also, in some cases, through a novel addition–elimination pathway. Indeed, ortho‐chloro‐ and ortho‐bromomethoxyarenes lead selectively to the corresponding ortho... hiện toàn bộ
