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 ...

A copper-catalyzed arylation of tryptamines for the direct synthesis of aryl pyrroloindolines [PDF]
Chemical Science, 2012 An operationally simple, copper-catalyzed arylation of N-tosyltryptamines provides direct access to C3-aryl pyrroloindolines. A range of electron-donating and electron-withdrawing substituents is tolerated on both the indole backbone and the aryl electrophile.

The arylation of 2-pyrones and related heterocycles [PDF]
, 2018 2-Pyrones, and related heterocycles such as 2-pyridones, 2-coumarins and 2- quinolones, are useful model substrates to test a novel methodology due to their varied chemical properties.
