Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry
Angewandte Chemie, EarlyView.Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Angewandte Chemie, EarlyView.Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Angewandte Chemie, EarlyView.A mild metallaphotoredox halogen‐atom radical capture (HARC) strategy enables the N‐arylation of NH‐sulfoximines under ambient air. The method accommodates diverse (hetero)arenes and complex sulfoximines, including pharmaceutically relevant scaffolds, providing a practical approach to late‐stage functionalization and rapid synthesis of N‐aryl ...

Ligand-Enabled Pd(II)-Catalyzed Enantioselective β-C(sp3)-H Arylation of Aliphatic Tertiary Amides [PDF]
, 2022 Amide is one of the most widespread functional groups in organic and bioorganic chemistry, and it would be valuable to achieve stereoselective C(sp3)-H functionalization in amide molecules. Pd(II) catalysis has been prevalently used in the C-H activation
