Synthesis and Reactivity of Mononuclear Iron Models of [Fe]-Hydrogenase that Contain an Acylmethylpyridinol Ligand

[Fe]-hydrogenase has a single iron-containing active site that features an acylmethylpyridinol ligand. This unique ligand environment had yet to be reproduced in synthetic models; however the synthesis and reactivity of a new class of small molecule mimics ...

Effect of ammonia on the decomposition of ammonium formate over Au/TiO2 under oxidizing conditions relevant to SCR: Enhancement of formic acid decomposition rate and CO2 production

Oliver Kröcher

Ammonium formate (AmFo) and formic acid decomposition were carried out in the presence of excess O-2 and H2O over 0.5 wt%Au/TiO2 anatase monolithic catalysts using various contact times and temperatures between 160 degrees C and 300 degrees C, under spray ...

Real Time Determination of the Electronic Structure of Unstable Reaction Intermediates during Au2O3 Reduction

Chemical reactions are always associated with electronic structure changes of the involved chemical species. Determining the electronic configuration of an atom allows probing its chemical state and gives understanding of the reaction pathways. However, of ...

Mechanistic Study on the Palladium(II)-Catalyzed Synthesis of 2,3-Disubstituted Indoles Under Aerobic Conditions: Anion Effects and the Development of a Low-Catalyst-Loading Process

Qian Wang, Jieping Zhu, Bo Yao

As a result of detailed mechanistic and kinetic studies, we have proposed that PdX2-catalyzed oxidative coupling of o-alkynylanilines 1 with terminal alkynes 2 under aerobic conditions is initiated by aminopalladation of 1 followed by ligand exchange of th ...

Electrochemical Stability of Imidazolium Based Ionic Liquids Containing Cyano Groups in the Anion: A Cyclic Voltammetry, XPS and DFT Study

Paul Joseph Dyson, Zhaofu Fei, Alexander Wokaun

The electrochemical stability of ionic liquids based on the 1-ethyl-3-methyl imidazolium EMIM cation and three different anions, dicyanoamide (N(CN)(2)), tricyanomethanide (C(CN)(3)) and tetracyanoborate (B(CN)(4)), has been investigate ...

Hierarchical Assembly and Reticulation of Two-Dimensional Mn- and Ni-TCNQ(x) (x=1, 2,4) Coordination Structures on a Metal Surface

Klaus Kern, Sebastian Stepanow, Tzu-Chun Tseng, Nasiba Abdurakhmanova

We report a scanning tunneling microscopy (STM) investigation of the self-assembly of two-dimensional metal-organic coordination networks comprised of Mn or Ni atoms (M) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) molecules on a Ag(100) surface. The growth ...

A bright tetranuclear iridium(III) complex

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Davide Di Censo

A cyclic tetranuclear cyclometallated iridium(III) complex using cyanide anions as bridging ligands and displaying a tetrahedrally distorted square geometry has been obtained with high yield; photo- and electrochemical characterizations show that most inte ...

Styrene oxidation by hydrogen peroxide in ionic liquids: the role of the solvent on the competition between two Pd-catalyzed processes, oxidation and dimerization

Paul Joseph Dyson, Cinzia Chiappe

A series of hydrophilic N,N-dimethylpyrrolidinium-and N,N-dimethylpiperidinium-based ionic liquids (ILs) have been prepared and applied as reaction media in the Wacker oxidation of styrene by hydrogen peroxide using PdCl2 as the catalyst. The efficiency of ...

Design of Dye Acceptors for Photovoltaics from First-Principles Calculations

Michael Graetzel, Mohammad Khaja Nazeeruddin, Efthimios Kaxiras, Sheng Meng

We investigate a set of donor-pi-acceptor (D-pi-A) dyes with new acceptor groups for dye-sensitized solar cells, using time-dependent density-functional-theory calculations of the electronic structure and optical absorption. We considered three types of mo ...

The biphenyl-monitored effective size of unsaturated functional or fluorinated ortho substituents

The size of a series of typical substituents has been probed by dynamic NMR measurements of the barriers to aryl-aryl rotation of the corresponding biphenyls. The resulting B values are meaningful because only mono-ortho substituted compounds were investig ...
