Self‐Assembly of a Customizable Library of Nickel Trifluoromethylation Catalysts via Selective C─F and C─O Bond Cleavage

open access: yesAngewandte Chemie, EarlyView.
Carbatranes and anionic pincer ligands were self‐assembled via one‐pot C─F or C─O bond cleavage and the formation of C─O, C─N, or C─C bonds, forming ligand architectures inaccessible by common synthetic methods. This approach allowed to build a customizable library of nickel catalysts for light‐induced C─H bond trifluoromethylation.

Direct Activation of Sulfides by C–H Oxidation with Photoexcited Nitroarenes: Formal Manipulations of the C─S Bond

open access: yesAngewandte Chemie, EarlyView.
Photochemical anaerobic oxidation of sulfides, using nitroarenes as bifunctional reagents, enables the formal manipulation of the C─S bond. The method allows direct and selective access to versatile carbonyl compounds from largely inert sulfides by C–H oxidation, thus avoiding multistep activation by sulfur oxidation.

Nickel‐Catalyzed Suzuki–Miyaura Cross‐Coupling Reaction of Aliphatic Alcohol Derivatives

open access: yesAngewandte Chemie, EarlyView.
A nickel‐catalyzed Suzuki–Miyaura coupling reaction of aliphatic mesylates is reported. This reaction provides a strategy for late‐stage functionalization of bioactive compounds that have high F(sp3). Preliminary mechanistic experiments confirm a stereoablative reaction outcome, consistent with alkyl radical intermediates.
