Redox‐Neutral Vicinal Dialkylation of Aryl Boronic Esters via the Palladium/Norbornene Cooperative Catalysis

Angewandte Chemie, EarlyView.
A new mode of the palladium/norbornene (Pd/NBE) cooperative catalysis, that is, redox‐neutral difunctionalization of aryl boronic esters with two electrophiles, has been developed, which can be used to streamline the preparation of a functionalized benzoazepane.

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

Crystal structure of ethyl 1′,5-dimethyl-2′′,3-dioxo-3H-dispiro[benzo[b]thiophene-2,3′-pyrrolidine-2′,3′′-indoline]-4′-carboxylate

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C23H22N2O4S, crystallized with two independent molecules (A and B) in the asymmetric unit. They have very similar conformations with the pyrrolidine ring having a twisted conformation, on the Cspiro—Cspiro bond, in both molecules.
