Angewandte Chemie, EarlyView.A new type of Si─Me bond activation enabling catalytic alkyl exchange at Si was developed. It involves a P‐directing group and Pd─Lewis acid cooperation. It enables the conversion of Me3SiCl into silanols with three different organic substituents. ABSTRACT A novel mode of Si─Me bond activation has been unveiled through the cooperative action of a P ...

Cobalt-Catalyzed Enantioselective C–H Arylation of Indoles
, 2022 International audienceAtropoisomeric (hetero)biaryls are scaffolds with increasing importance in the pharmaceutical and agrochemical industries. Although it is the most obvious disconnection to construct such compounds, the direct enantioselective C-H ...

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

C-H bond Activation/Arylation over Arene-Ruthenium(II)-picolinate Complexes: Synthesis, Structure and Catalytic Activity [PDF]
, 2017 A series of water soluble arene-ruthenium(II) complexes [(η6-arene)RuCl(κ2-L)]n+ (n = 0, 1) ([Ru]-1 – [Ru]-12) containing pyridine based N,O or N,N ligands (L1-L6) were synthesized and employed for the catalytic C-H bond activation/ arylation of 2 ...

Angewandte Chemie, EarlyView.Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.
