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.Catalyst‐controlled nitrene transfer unlocks divergent reactivity of bicyclo[1.1.0]butanes. Rhodium catalysis promotes selective strain‐release amination to access cyclobutene and cyclobutane amino‐acid scaffolds, whereas visible‐light photocatalysis redirects nitrene reactivity toward double amination and skeletal remodeling, providing a complementary

Unexpected Rearrangement of 2-Bromoaniline under Biphasic Alkylation Conditions
, 2017 Alkylation of 2-bromoaniline with benzyl bromide under ostensibly basic N-alkylation conditions resulted in migration of bromine from the 2- to the 4-aryl position.

Angewandte Chemie, EarlyView.ROXendin668 is a peptidic GLP‐1 receptor agonist that generates toxic singlet oxygen upon irradiation with far‐red light. Pancreatic beta cells can be photo‐ablated in a spatiotemporally controlled manner. This approach has the potential to provide a safer alternative to streptozotocin or alloxan for creating model systems for type 1 diabetes research.
