Aziridination of Olefins by a Copper Phenanthroline Catalyst

ChemistryEurope, EarlyView.
A redox‐active Cu(I)‐photocatalyst is evaluated for the aziridination of alkenes. Especially styrenes and electron‐rich 1,3‐dienes are found to be suitable substrates, allowing short reaction times (10 min) at low catalyst loading (1 mol%). The activation of the copper(I) complex by light is compared to the process in the dark. The direct aziridination

Continuous Flow Oxidation of Alcohols to Carboxylic Acids Using a Ternary Pd/C‐Pt/C‐Ru/C Catalyst and Molecular Oxygen. Application to the Synthesis of 2,5‐Frandicarboxylic Acid

ChemistryEurope, EarlyView.
A ternary metal catalyst system based on Pd/C, Pt/C, and Ru/C is found to be highly effective and robust for oxidizing alcohols to carboxylic acids using molecular oxygen. Combining the catalytic oxidation system with continuous flow, the conversion of 5‐hydroxymethylfurfural (HMF) into 2,5‐furandicarboxylic acid (FDCA), a bioplastics precursor, is ...

Enantio‐ and Diastereoselective Rh(I)‐Catalyzed Defluorinative Arylation of Pentafluoroethyl Alkenes to Access Fluoroalkenes Featuring a Unique F‐ and CF3‐Substituted sp2‐Carbon†

Chinese Journal of Chemistry, EarlyView.
A highly enantio‐ and diastereoselective rhodium(I)‐catalyzed defluorinative arylation of pentafluoroethyl alkenes has been developed. Both 1,1‐ and 1,2‐disubstituted alkenes were compatible leading to tetra‐ and trisubstituted fluoroalkenes, respectively, in excellent Z/E selectivities.

Effects of Ambient and Display Lighting Color on Risk‐Taking Behavior, Perceived Emotional States, and Visual Quality of Indoor Environment

Color Research &Application, EarlyView.
In a digital risk‐taking test, participants inflated a balloon to increase earned points at the risk of popping under different display and ambient lighting conditions. ABSTRACT Lighting from architectural fixtures and screens can have impacts beyond visual perception, such as occupants' cognitive functions and emotional states. Despite the ubiquity of
