Cross-Coupling of Alkyl Redox-Active Esters with Benzophenone Imines: Tandem Photoredox and Copper Catalysis

Xile Hu, Runze Mao

Alkyl amines are an important class of organic compounds in medicinal and materials chemistry. Until now very have been very few methods for the synthesis of alkyl amines by metal‐catalyzed cross‐coupling of alkyl electrophiles with nitrogen nucleophiles. ...

Solar-driven reduction of CO₂ : from homogeneous to heterogeneous catalytic systems

Marcel Roland Schreier

Rapidly increasing levels of atmospheric carbon dioxide and their damaging impact on the global climate system raise doubts about the sustainability of the fossil resource based energy system. Meanwhile, raising living standards and increasing global popul ...

A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Puppo

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists o ...

Investigation of the Structural and Electrochemical Properties of Mn2Sb3O6CI upon Reaction with Li Ions

Iwan Zimmermann

The structural and electrochemical properties of a quaternary layered compound with elemental composition Mn2Sb3O6Cl have been investigated upon reaction with lithium in Li half cells. Operando XRD was used to investigate the potential impact of this parti ...

Total Synthesis of (±)-Strictamine

Jieping Zhu, Qian Wang, Weiwu Ren

The total synthesis of strictamine has been achieved in nine steps from a known enol triflate. Characteristic features of our approach included: a) creation of a C7 all-carbon quaternary stereocenter at an early synthetic stage; b) use of an N,N-dimethyl t ...

Copper-Catalyzed Cyanomethylation of Allylic Alcohols with Concomitant 1,2-Aryl Migration: Efficient Synthesis of Functionalized Ketones Containing an α-Quaternary Center

Jieping Zhu, Qian Wang, Ala Bunescu

A copper-catalyzed alkylation of allylic alcohols by alkyl nitriles with concomitant 1,2-aryl migration was developed. Formation of the alkyl nitrile radical was followed by its intermolecular addition to alkenes and the migration of a vicinal aryl group w ...

Electrochemical Reduction of CO2 Catalyzed by Metal Oxides

Yeonji Oh

A rapidly growing population and industrialization have caused the exploitation of natural resources in keeping with fossil fuels shortage. Due to the combustion of fossil fuels, the concentration of CO2 in the earth's atmosphere, which is a potent greenho ...

Influence of Elemental Iodine on Imidazolium-Based Ionic Liquids: Solution and Solid-State Effects

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Felix Daniel Bobbink, Emilia Paunescu

Ionic liquids doped with I-2, usually resulting in the formation of polyiodide anions, are extensively used as electrolytes and in iodination reactions. Herein, NMR spectroscopy and single-crystal X-ray diffraction were used to rationalize the structures o ...
