Getting the Right Grip? How Understanding Electrophile Selectivity Profiles Could Illuminate Our Understanding of Redox Signaling

Recent Advances: Herein, we focus on the first step of this process, electrophile sensing. Electrophile sensing is typically a deceptively simple reaction between the thiol of a protein cysteine, of which there are around 200,000 in the human proteome, and ...

Four-electron Reduction and Functionalization of N₂ by a Uranium(III) Bridging Nitride

Marinella Mazzanti, Marta Falcone

N2 is a cheap and widely available but very unreactive molecule. Notably, the only industrial process for the conversion of dinitrogen is the Haber-Bosch process to form ammonia, but under very harsh conditions (high temperature and pressure). Here, we rev ...

Equilibrium and Out-of-Equilibrium Adherence of Hydrogels against Polymer Brushes

Costantino Creton, Jennifer Mary Adrienne Alice Macron

At low pH, underwater adherence between poly(N,N-dimethylacrylamide) hydrogels and poly(acrylic acid) brushes is due to the formation of multiple hydrogen bonds. The effect of the key parameters controlling the formation of these interactions (contact time ...

Nitrogen reduction and functionalization by a multimetallic uranium nitride complex

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Lucile Sylvie Danielle Chatelain, Marta Falcone

Molecular nitrogen (N-2) is cheap and widely available, but its unreactive nature is a challenge when attempting to functionalize it under mild conditions with other widely available substrates (such as carbon monoxide, CO) to produce value-added compounds ...

Metathesis of a U(V) imido complex: a route to a terminal U(V) sulfide

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone, Rory Patrick Kelly

Herein, we report the synthesis and characterisation of the first terminal uranium(V) sulfide and a related UV trithiocarbonate complex supported by sterically demanding tris(tert-butoxy)siloxide ligands. The reaction of the potassium-bound UV imido comple ...

Stereoselective synthesis of alkenes via base-metal-catalyzed addition reactions to alkynes and activation of hydrogen peroxide and carbon dioxide by iron complexes

Fedor Zhurkin

Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...

On-Surface Assembly and Reactions of Organic Molecules in Ultra-High Vacuum

Claudius Morchutt

This thesis comprises the study of two types of 2D materials, those stabilized by non-covalent and those by covalent interactions. They are synthesized and studied on well-defined metallic surfaces in ultra-high vacuum (UHV). The self-assembly of terephtha ...

Molecular bonding with the RPAx: From weak dispersion forces to strong correlation

Nicola Colonna

In a recent paper [Phys. Rev. B 90, 125102 ( 2014)], we showed that the random phase approximation with exchange (RPAx) gives accurate total energies for a diverse set of systems including the high and low density regime of the homogeneous electron gas, th ...

Facile CO Cleavage by a Multimetallic CsU2 Nitride Complex

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone

Uranium nitrides are important materials with potential for application as fuels for nuclear power generation, and as highly active catalysts. Molecular nitride compounds could provide important insight into the nature of the uranium–nitride bond, but curr ...

Development of prediction models for the reactivity of organic compounds with ozone in aqueous solution by quantum chemical calculations: Role of delocalized and localized molecular orbitals

Jeremy Samuel Arey, Urs von Gunten, Saskia Gisela Zimmermann-Steffens, Minju Lee, Kathrin Fenner

Second-order rate constants (k(O3)) for the reaction of ozone with micropollutants are essential parameters for the assessment of micropollutant elimination efficiency during ozonation in water and wastewater treatment. Prediction models for k(O3) were dev ...

Adducts of Nitrous Oxide and N-Heterocyclic Carbenes: Syntheses, Structures, and Reactivity

Kay Severin, Rosario Scopelliti, Euro Solari, Basile Vuichoud, Alexander Tskhovrebov

N-Heterocyclic carbenes (NHCs) react at ambient conditions with nitrous oxide to give covalent adducts. In the crystal, all compounds show a bent N2O group connected via the N-atom to the former carbene carbon atom. Most adducts are stable at room temperat ...

How Strong Is Hydrogen Bonding in Ionic Liquids? Combined X-ray Crystallographic, Infrared/Raman Spectroscopic, and Density Functional Theory Study

Gabor Laurenczy, Rosario Scopelliti, Paul Joseph Dyson, Zhaofu Fei, Ning Yan, Emilia Paunescu

Hydrogen bonding in ionic liquids based on the 1-(2'-hydroxylethyl)-3-methylimidazolium cation (C(2)OHmim) and various anions (A) of differing H-bond acceptor strength, viz. hexafluorophosphate PF6, tetrafluoroborate BF4, bis-(trifluoro ...
