CO2 Capture and Release in Amine Solutions: To What Extent Can Molecular Simulations Help Understand the Trends?

Wanda Andreoni, Fabio Pietrucci, Changru Ma

Absorption in amine solutions is a well-established advanced technology for CO2 capture. However, the fundamental aspects of the chemical reactions occurring in solution still appear to be unclear. Our previous investigation of aqueous monoethanolamine (ME ...

Reactions of amines with ozone and chlorine: Two novel oxidative methods to evaluate the N-DBP formation potential from dissolved organic nitrogen

Urs von Gunten, Karim-Alexandre Essaied, Lucy Victoria Brown

The composition of oxidant-reactive dissolved organic nitrogen (DON) is poorly characterized, although its ozonation is likely to form a great variety of disinfection by-products containing a nitrogen-oxygen bond (NDBPs). In this study, two chemical oxidat ...

Direct Photoexcitation of Ethynylbenziodoxolones: An Alternative to Photocatalysis for Alkynylation Reactions**

Jérôme Waser, Franck Le Vaillant, Stephanie Grace Elizabeth Amos, Diana Cavalli

Ethynylbenziodoxolones (EBXs) are commonly used as radical traps in photocatalytic alkynylations. Herein, we report that aryl-substituted EBX reagents can be directly activated by visible light irradiation. They act as both oxidants and radical traps, alle ...

Enhanced Treatment of Municipal Wastewater Effluents by Fe-TAML/H2O2: Efficiency of Micropollutant Abatement

Urs von Gunten

Combining iron with a tetraamido-macrocyclic ligand (Fe-TAML) as a catalyst and with hydrogen peroxide (H2O2) as the bulk oxidant is a process that has been suggested for the oxidative abatement of micropollutants during water treatment. In this study, the ...

Shape and size control of colloidal CdSe nanocrystals in the presence of carboxylate and alkylamine ligands

Xiaopeng Huang

In this thesis, we focus on investigating the shape and size evolution of colloidal CdSe nanomaterials in the presence of carboxylate and alkylamine surface ligands. By elaborating the combination of carboxylates and alkylamines with different hydrocarbon ...

Applying a Trojan Horse Strategy to Ruthenium Complexes in the Pursuit of Novel Antibacterial Agents

Paul Joseph Dyson, Lucinda Kate Batchelor, Quentin François Antoine Laurent

Siderophores are iron chelators secreted by bacteria to scavenge iron(III) from their surrounding environment. They possess their own internalization pathway that is sufficiently unselective to be hijacked, making them suitable for Trojan Horse strategy ap ...

Dearomatization of electron poor six-membered N-heterocycles through [3+2] annulation with aminocyclopropanes

Jérôme Waser, Johannes Preindl, Shyamal Chakrabarty

Many abundant and highly bioactive natural alkaloids contain an indolizidine skeleton. A simple, high yielding method to synthesize this scaffold from N-heterocycles was developed. A wide range of pyridines, quinolines and isoquinolines reacted with donor- ...

Around isocyanide reactivity : development of enantioselective transformations and syntheses of heterocycles and natural products

Antonin François Roland Clemenceau

This manuscript covers two main topics. The first part dealt with the organocatalytic conjugate addition of Michael donors to phenyl vinyl selenone. The enantioselective Cinchona alkaloid-catalyzed Michael addition using a-substituted a-nitroacetates has b ...

Chemoselective three-phase hydrogenation of an Ombrabulin nitro-stilbene intermediate in a continuous-flow mobile platform

Lioubov Kiwi, Charline Berguerand

The chemoselective three-phase hydrogenation of an Ombrabulinintermediate based on a nitro-stilbene framework was used as a case study for the formation of the primary amine without affecting the double bond. Two catalysts were tested: Pt nanoparticles sup ...
