Energy Transfer Catalysis Enabled 2,2,2‐Trifluoroethoxy‐Amination of Olefins
ChemistryEurope, EarlyView.A thioxanthone‐catalyzed 2,2,2‐trifluoroethoxyamination of olefins is developed using unprecedented, easily prepared, and bench‐stable oxime ethers via the generation of alkoxy and iminyl radicals. The controlled intermolecular addition of the alkoxy radical to an olefin, over possible competing side processes, is critical.

The Energetics of Electron Transfer in Redox‐DNA Layers Mimics That of Redox Proteins
Chemistry – A European Journal, EarlyView.The electron transfer in ferrocene‐labeled DNA (Fc‐DNA) layers mimics that of redox proteins, featuring a low reorganization energy (λ). The origin of the low λ in Fc‐DNA was unveiled by high‐scan‐rate cyclic voltammetry and molecular dynamics simulations, implying Fc‐DNA as a versatile tool to open new avenues in understanding the ET in biological ...

Intramolecular PCET of α‐Keto Acids: Synthesis of Trifluoromethyl Ketones via Ketyl Radicals
Chemistry – A European Journal, EarlyView.Decarboxylation of α‐keto acids have conventionally served as simple building blocks for the generation of nucleophilic acyl radicals. Herein, we demonstrate a distinct approach for this substrate class, showcasing the generation of ketyl radicals through a proton‐coupled electron transfer (PCET) mechanism.
