Surface segregation in high-entropy alloys from alchemical machine learning
Michele Ceriotti, Guillaume André Jean Fraux, Arslan Mazitov, Sandip De, Nataliya Lopanitsyna
High-entropy alloys (HEAs), containing several metallic elements in near-equimolar proportions, have long been of interest for their unique mechanical properties. More recently, they have emerged as a promising platform for the development of novel heterog ...
Bristol2024Regiodivergent and Enantioselective Synthesis of Cyclic Sulfones via Ligand-Controlled Nickel-Catalyzed Hydroalkylation
Cyclic sulfones have demonstrated important applications in drug discovery. However, the catalytic and enantioselective synthesis of chiral cyclic sulfones remains challenging. Herein, we develop nickel-catalyzed regiodivergent and enantioselective hydroal ...
Wiley-V C H Verlag Gmbh2024Theory-guided development of homogeneous catalysts for the reduction of CO2 to formate, formaldehyde, and methanol derivatives
Matthew Wodrich, Shubhajit Das, Anne-Clémence Corminboeuf, Hanna Hinrika Cramer
The stepwise catalytic reduction of carbon dioxide (CO2) to formic acid, formaldehyde, and methanol opens non-fossil pathways to important platform chemicals. The present article aims at identifying molecular control parameters to steer the selectivity to ...
2023Synthesis, isolation and application of a sila-ketenyl anion
Rosario Scopelliti, Shiori Fujimori
Ynolates or ketenyl anions, [RCCO]-, are negatively charged reactive intermediates, which can be generated in situ and used for divergent chemical transformations. Ynolates can react either at the oxygen or carbon centres or across the C-C triple bond, mak ...
London2023Photocatalyzed [2σ + 2σ] and [2σ + 2π] Cycloadditions for the Synthesis of Bicyclo[3.1.1]heptanes and 5- or 6-Membered Carbocycles
Jérôme Waser, Matthew Wodrich, André Bossonnet
We report the use of photocatalysis for the homolytic ring-opening of carbonyl cyclopropanes. In contrast to previous studies, our approach does not require a metal cocatalyst or a strong reductant. The carbonyl cyclopropanes can be employed for both [2σ + ...
2023Development of Cyclopentadienylcobalt(III) Catalyzed Asymmetric C-H Functionalizations
Transition metal catalyzed C-H activation plays a major role in modern organic chemistry, affording mild, selective and atom-efficient protocols. Most of current developments in the field rely on the use of several precious metals. As a consequence, an int ...
EPFL2022Mapping Catalyst‐Solvent Interplay in Competing Carboamination/Cyclopropanation Reactions
Nicolai Cramer, Matthew Wodrich, Miyeon Chang, Simone Gallarati
Group 9 metals, in particular Rh III complexes with cyclopentadienyl ligands, are competent C–H activation catalysts. Recently, a Cp*Rh III catalyzed reaction of alkenes with N -enoxyphthalimides showed divergent outcome based on the solvent, with carboami ...
2022Galvanic replacement reactions of Ga and In with Cu for the synthesis of bimetallic nanoparticles
The need for efficient and selective catalysts, capable of driving important conversions to build a more sustainable society, encourages the development of synthetic approaches towards new nanomaterials. Cu-based bimetallic nanoparticles (NPs) promise to f ...
EPFL2022Streamlined Alkylation via Nickel-Hydride-Catalyzed Hydrocarbonation of Alkenes
Xile Hu, Chao Fan, Srikrishna Bera, Zhikun Zhang
Compounds rich in sp(3)-hybridized carbons are desirable in drug discovery. Nickel-catalyzed hydrocarbonation of alkenes is a potentially efficient method to synthesize these compounds. By using abundant, readily available, and stable alkenes as pro-nucleo ...
AMER CHEMICAL SOC2022Chiral Diimine Complexes of Earth-Abundant Transition Metals for Asymmetric Catalysis
The application of Earth-abundant metals in asymmetric catalysis is key to transition towards a more sustainable chemistry. In particular, expanding the library of redox-active ligands capable of supporting Earth-abundant metals is essential in order to re ...
