Induction of Motion in a Synthetic Molecular Machine: Effect of Tuning the Driving Force
05.04.2013 | Jacob Baggerman, Natalia Haraszkiewicz, Piet G. Wiering, Giulia Fioravanti, Massimo Marcaccio, Francesco Paolucci, E ..., Chemistry - A European Journal, 2013
Abstract Rotaxane molecular shuttles were studied in which a tetralactam macrocyclic ring moves between a succinamide station and a second station in which the structure is varied. Station 2 in all cases is an aromatic imide, which is a poor hydrogen‐bond acceptor in the neutral form, but ...
Confinement of Chemisorbed Phosphates in a Controlled Nanospace with Three‐Dimensional Mesostructures
05.04.2013 | Jie Yang, Liang Zhou, Jun Zhang, Jin Zou, Zhiguo Yuan, Chengzhong Yu, Chemistry - A European Journal, 2013
Abstract The confinement of phosphates inside adsorbents is important for not only entrophication control, but also the recovery of phosphorous, a depleting natural resource. However, the behaviour of chemisorbed phosphates inside nanoporous materials has not been systematically studied. ...
TIPS‐TTF as a Precursor of Low‐Symmetry TTF Derivatives: Steric Protection Strategy in the Regioselective CH Modification of TTF
04.04.2013 | Ryota Ueno, Daishi Fujino, Hideki Yorimitsu, Atsuhiro Osuka, Chemistry - A European Journal, 2013
Abstract Triisopropylsilyltetrathiafulvalene (TIPS‐TTF) has been devised as a promising platform for the synthesis of low‐symmetry TTF derivatives. The bulky TIPS group allows TIPS‐TTF to undergo palladium‐catalyzed direct diarylation as well as LDA‐mediated dilithiation exclusively on ...
Highly Effective Water Oxidation Catalysis with Iridium Complexes through the Use of NaIO4
04.04.2013 | Zoel Codolà, João M. S. Cardoso, Beatriz Royo, Miquel Costas, Julio Lloret‐Fillol, Chemistry - A European Journal, 2013
Abstract Exceptional water oxidation (WO) turnover frequencies (TOF=17 000 h−1), and turnover numbers (TONs) close to 400 000, the largest ever reported for a metal‐catalyzed WO reaction, have been found by using [Cp*IrIII(NHC)Cl2] (in which ...
Graphene‐Assisted Room‐Temperature Synthesis of 2D Nanostructured Hybrid Electrode Materials: Dramatic Acceleration of the Formation Rate of 2D Metal Oxide Nanoplates Induced by Reduced Graphene Oxide Nanosheets
04.04.2013 | Da‐Young Sung, Jayavant L. Gunjakar, Tae Woo Kim, In Young Kim, Yu Ri Lee, Seong‐Ju Hwang, Chemistry - A European Journal, 2013
Abstract A new prompt room temperature synthetic route to 2D nanostructured metal oxide–graphene‐hybrid electrode materials can be developed by the application of colloidal reduced graphene oxide (RGO) nanosheets as an efficient reaction accelerator for the synthesis of δ‐MnO2 2D ...
Highly Enantioselective Aldol Reactions between Acetaldehyde and Activated Acyclic Ketones Catalyzed by Chiral Primary Amines
04.04.2013 | Yu‐Hua Deng, Jin‐Quan Chen, Long He, Tai‐Ran Kang, Quan‐Zhong Liu, Shi‐Wei Luo, Wei‐Chen Yuan, Chemistry - A European Journal, 2013
Abstract Highly enantioselective cross‐aldol reactions between acetaldehyde and activated acyclic ketones are reported for the first time. Various acyclic ketones, such as saturated and unsaturated keto esters, reacted with acetaldehyde in the presence of a chiral primary amine and a ...
Transition‐Metal‐Free One‐Pot Synthesis of Biaryls from Grignard Reagents and Substituted Cyclohexanones
04.04.2013 | Feng Zhou, Marc‐Oliver Simon, Chao‐Jun Li, Chemistry - A European Journal, 2013
Abstract A new strategy for the construction of biaryls by a transition‐metal‐free process is presented. A sequence of a Grignard reaction, dehydration, and oxidative aromatization affords the desired products in a one‐pot fashion. One‐pot biaryl synthesis: An efficient method for ...
Crystal‐Facet Engineering of Ferric Giniite from Ionic‐Liquid Precursors and Their Enhanced Photocatalytic Performances under Visible‐Light Irradiation
28.03.2013 | Xiaochuan Duan, Di Li, Huili Zhang, Jianmin Ma, Wenjun Zheng, Chemistry - A European Journal, 2013
Abstract In the work presented here, well‐dispersed ferric giniite microcrystals with controlled sizes and shapes are solvothermally synthesized from ionic‐liquid precursors by using 1‐n‐butyl‐3‐methylimidazolium dihydrogenphosphate ([Bmim][H2PO4]) as phosphate source. The success of this ...
Catalytic Asymmetric Construction of Quaternary α‐Amino Acid Containing Pyrrolidines through 1,3‐Dipolar Cycloaddition of Azomethine Ylides to α‐Aminoacrylates
28.03.2013 | Zheng Wang, Shuai Luo, Shoude Zhang, Wu‐Lin Yang, Yang‐Zi Liu, Honglin Li, Xiaoyan Luo, Wei‐Ping Deng, Chemistry - A European Journal, 2013
Abstract The first catalytic enantioselective 1,3‐dipolar cycloaddition of azomethine ylides to α‐aminoacrylate catalyzed by a AgOAc/ferrocenyl oxazolinylphosphine (FOXAP) system was developed, which exhibits excellent exo‐ and enantioselectivity (92–99 % ee). This process provides ...
Unimolecular Reaction Mechanism of an Imidazolin‐2‐ylidene: An iPEPICO Study on the Complex Dissociation of an Arduengo‐Type Carbene
28.03.2013 | Patrick Hemberger, Andras Bodi, Thomas Gerber, Max Würtemberger, Udo Radius, Chemistry - A European Journal, 2013
Abstract The photoionization and dissociative photoionization of Im(iPr)2, 1,3‐diisopropylimidazolin‐2‐ylidene, was investigated by imaging photoelectron photoion coincidence (iPEPICO) with vacuum ultraviolet (VUV) synchrotron radiation. A lone‐pair electron of the carbene carbon atom is ...
