CO2 conversion to isocyanate via multiple N–Si bond cleavage at a bulky uranium(III) complex

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reaction of the sterically saturated uranium(III) tetrasilylamido complex [K(18c6)][U(N(SiMe3)(2))(4)] with CO2 leads to CO2 insertion into the U-N bond affording the stable U(IV) isocyanate complex [K(18c6)]U(N(SiMe3)(2))(3)(NCO)(2) that was crys ...

Competing Interactions in the Self-Assembly of NC-Ph-3-CN Molecules on Cu(111)

Harald Brune, Marina Pivetta, Giulia Elisabetta Pacchioni

We report on low-temperature scanning tunneling microscopy and spectroscopy measurements on NC-Ph-3-CN molecules adsorbed at 300 K on a Cu(111) surface. Upon cooling, the molecules form chain and honeycomb structures, incorporating Cu adatoms supplied by t ...

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

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

Strain-Promoted C-C Bond Cleavages of Cyclobutanes

Laetitia Marie Mélanie Souillart

The catalytic activation of carbon-carbon single bonds is a major challenge in organometallic chemistry, since the lack of prefunctionalization steps opens the way to new, economically and ecologically attractive reaction pathways. Strained ring substrates ...

Highly Enantioselective Rhodium(I)-Catalyzed Activation of Enantiotopic Cyclobutanone C-C Bonds

Nicolai Cramer, Laetitia Marie Mélanie Souillart

The selective functionalization of carbon-carbon sigma bonds is a synthetic strategy that offers uncommon retrosynthetic disconnections. Despite progress in CC activation and its great importance, the development of asymmetric reactions lags behind. Rhodiu ...

Probing the electronic and geometric structure of ferric and ferrous myoglobins in physiological solutions by Fe K-edge absorption spectroscopy

Majed Chergui, Ursula Röthlisberger, Ivano Tavernelli, Thomas James Penfold, Marco Eli Reinhard, Frederico Alves Lima

We present an iron K-edge X-ray absorption study of carboxymyoglobin (MbCO), nitrosylmyoglobin (MbNO), oxymyoglobin (MbO(2)), cyanomyoglobin (MbCN), aquomet myoglobin (metMb) and unligated myoglobin (deoxyMb) in physiological media. The analysis of the XAN ...

"New methods for indoles and [3,4]-fused oxindoles syntheses" and "Copper-catalyzed/mediated difunctionalization of alkenes with alkylnitriles"

Ala Bunescu

Two main topics were addressed in this manuscript: (1) New methods for indoles and [3,4]-fused oxindoles syntheses; (2) Copper-catalyzed/mediated difunctionalization of alkenes with alkylnitriles. Given the omnipresent character of the indole and oxindole ...

Modelling of the bond behaviour of tuff elements externally bonded with FRP sheets

Angelo Garofano

The performance of fibre reinforced plastic (FRP) materials used for external strengthening depends strongly on the bond behaviour at the FRP-substrate interface. In this paper, the results of an analytical model and of two Finite Element (FE) models (bi-a ...
