Enantioselective Rhodium-catalyzed C-C Bond Activation of Cyclobutanones

Nicolai Cramer, Laetitia Marie Mélanie Souillart

The activation of carbon-carbon bonds has attracted much attention in the past decade. Despite important progress, the development of asymmetric reactions lags behind. For the first time, asymmetric rhodium(I)-catalyzed direct oxidative additions into enan ...

Catalytic C-C Bond Activations via Oxidative Addition to Transition Metals

Nicolai Cramer, Laetitia Marie Mélanie Souillart

Selective cleavages of carbon-carbon bonds catalyzed by transition-metal complexes have been shown to be increasingly versatile tools for organic synthesis allowing for complementary synthetic strategies. Numerous examples of transition-metal catalyzed C-C ...

Synthesis of Functionalized Epoxides by Copper-Catalyzed Alkylative Epoxidation of Allylic Alcohols with Alkyl Nitriles

Qian Wang, Jieping Zhu, Ala Bunescu

A copper-catalyzed oxyalkylation of allylic alcohols using nonactivated alkyl nitriles as reaction partners was developed. A sequence involving generation of an alkyl nitrile radical followed by its addition to a double bond and a copper-mediated formation ...

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 ...

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 ...

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 ...

Synthesis of poly(ethylene-co-butylene)-block-poly(ethylene oxide) surfactant and its use in the synthesis of polyhydroxyethyl methacrylate nanoparticles containing azo-dye

Thomas Geiger, Yee Song Ko

A synthetic path to poly(ethylene-co-butylene)-block-poly(ethylene oxide), a substitute for the "KLE" surfactant was developed. For this purpose, mono hydroxyl end-functionalized poly(ethylene-co-butylene) (similar to 3800 g mol(-1)) was modified with a tr ...

Fast and Highly Chemoselective Alkynylation of Thiols with Hypervalent Iodine Reagents Enabled through a Low Energy Barrier Concerted Mechanism

Jérôme Waser, Matthew Wodrich, Reto Frei, Durga Prasada Rao Hari

Among all functional groups, alkynes occupy a privileged position in synthetic and medicinal chemistry, chemical biology, and materials science. Thioalkynes, in particular, are highly useful, as they combine the enhanced reactivity of the triple bond with ...
