A microwave molecular solution based approach towards high-[small kappa]-tantalum(V)oxide nanoparticles: synthesis, dielectric properties and electron paramagnetic resonance spectroscopic studies of their defect chemistry

17-Nov-2015 | R. C. Hoffmann; M. Kaloumenos; D. Spiehl; E. Erdem; S. Repp; S. Weber; J. J. Schneider, Physical Chemistry Chemical Physics, 2015

Stable dispersions of tantalum oxide nanoparticles are accessible from solutions of tantalum(v) complexes with a mixed malonato and alkanolato ligand sphere in ethoxyethanol by microwave processing. The malonato ligand is cleaved during decomposition and acetic acid or acetic acid esters are ...


Hydrogen Peroxide Complex of Zinc

17-Nov-2015 | Christian M. Wallen; John Bacsa; Christopher C. Scarborough, Journal of the American Chemical Society, 2015

Metal(H2O2) complexes have been implicated in kinetic and computational studies but have never been observed. Accordingly, H2O2 has been described as a very weak ligand. We report the first metal(H2O2) adduct, which is made possible by incorporating intramolecular hydrogen-bonding interactions ...


Ultrasound-assisted chiral derivatization of etodolac with (1R)-(-)-menthyl chloroformate for the determination of etodolac enantiomers

15-Nov-2015 | Author(s): Yan Jin, Jing Zhao, Lydia Rhyman, Ponnadurai Ramasami, Yujin Shin, Kyung Min Jeong, Jeongmi Lee, Arabian Journal of Chemistry, 2015

Publication date: Available online 11 November 2015 Source:Arabian Journal of Chemistry Author(s): Yan Jin, Jing Zhao, Lydia Rhyman, Ponnadurai Ramasami, Yujin Shin, Kyung Min Jeong, Jeongmi Lee This study presents the first report of an ultrasound-assisted derivatization ...


Macrocyclic Platinum(II) Complexes with a Bifunctional Diphosphine Ligand

13-Nov-2015 | Andrea E. Pascui, Karlotta van Rees, Dirk W. Zant, Daniël L. J. Broere, Maxime A. Siegler, Jarl Ivar van der Vlugt, European Journal of Inorganic Chemistry, 2015

Abstract The preparation and coordination chemistry of a ditopic ligand scaffold (1H2), containing both a phosphorus‐donor (P) and a nitrogen‐donor (N) binding pocket, is reported. The ligand was synthesized by reductive amination from 3‐(diphenylphosphino)benzaldehyde and ...


Well‐controlled ATRP of 2‐(2‐(2‐azidoethyoxy)ethoxy)ethyl methacrylate for high‐density click functionalization of polymers and metallic substrates

12-Nov-2015 | Pingsheng Liu, Jie Song, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT The combination of atom transfer radical polymerization (ATRP) and click chemistry has created unprecedented opportunities for controlled syntheses of functional polymers. ATRP of azido‐bearing methacrylate monomers (e.g., 2‐(2‐(2‐azidoethyoxy)ethoxy)ethyl methacrylate, AzTEGMA), ...


Spontaneous Partitioning of Californium from Curium: Curious Cases from the Crystallization of Curium Coordination Complexes

12-Nov-2015 | Samantha K. Cary; Mark A. Silver; Guokui Liu; Jamie C. Wang; Justin A. Bogart; Jared T. Stritzinger; Alexandra A. Ar ..., Inorganic Chemistry, 2015

The reaction of 248CmCl3 with excess 2,6-pyridinedicarboxylic acid (DPA) under mild solvothermal conditions results in crystallization of the tris-chelate complex Cm(HDPA)3·H2O. Approximately half of the curium remains in solution at the end of this process, and evaporation of the mother liquor ...


Modeling of electron transfer across electrochemical interfaces: State‐of‐the art and challenges for quantum and computational chemistry

11-Nov-2015 | Renat R. Nazmutdinov, Michael D. Bronshtein, Tamara T. Zinkicheva, Dmitrii V. Glukhov, International Journal of Quantum Chemistry, 2015

State‐of‐the‐art in the area of quantum‐chemical modeling of electron transfer (ET) processes at metal electrode/electrolyte solution interfaces is reviewed. Emphasis is put on key quantities which control the ET rate (activation energy, transmission coefficient, and work terms). Orbital overlap ...


Ambient‐Temperature Synthesis of 2‐Phosphathioethynolate, PCS–, and the Ligand Properties of ECX– (E = N, P; X = O, S)

04-Nov-2015 | Andrew R. Jupp, Michael B. Geeson, John E. McGrady, Jose M. Goicoechea, European Journal of Inorganic Chemistry, 2015

Abstract A synthesis of the 2‐phosphathioethynolate anion, PCS–, under ambient conditions is reported. The coordination chemistry of PCO–, PCS– and their nitrogen‐containing congeners is also explored. Photolysis of a solution of W(CO)6 in the presence of PCO– [or a simple ligand displacement ...


Creating Reactivity with Unstable Endmembers using Pressure and Temperature: Synthesis of Bulk Cubic Mg0.4Fe0.6N

28-Oct-2015 | George Serghiou, Gang Ji, Nicholas Odling, Hans J. Reichmann, Jean‐Paul Morniroli, Reinhard Boehler, Dan J. Frost, J ..., Angewandte Chemie International Edition, 2015

Abstract Alloy and nitride solid solutions are prominent for structural, energy and information processing applications. There are frequently however barriers to making them. We remove barriers to reactivity here using pressure with a new synthetic approach. We target pressures where the ...
