The development of 3d-metal-catalyzed β-C–H bond activation via 4-membered metallacycles remains an elusive challenge. Here, the authors report a Ni-Al bimetal-catalyzed β-C(sp3)–H bond activation of formamides via 4-membered nickelacycles.

Transition metal-catalyzed C−H cyclization for medium-ring synthesis has been limited to reactive C−H bonds, the activation of unreactive C−H bonds still remains a challenge. Here the authors show the direct construction of 7-membered rings via

A chiral phosphine oxide-ligated Ni-Al bimetallic catalyst was used to realize an enantioselective C2-H alkylation of pyridines without the need of a C2-block. A wide range of pyridines, including unsubstituted pyridine, C3, C4, and C2-substituted py

Achieving the transition metal-catalysed pyridine C3-H alkenylation, with pyridine as the limiting reagent, has remained a long-standing challenge. Previously, we disclosed that the use of strong coordinating bidentate ligands can overcome catalyst d

Following the age of directing group, anchoring catalysis starts coming to the center of the stage. Different from the directing-group strategy that needs a preinstalled directing group in substrates, anchoring catalysis relies on a reversible intera

Enantioselective Ni-catalyzed C(spsup3/sup)-H bond activation remains an elusive challenge. Herein, we used phosphine oxide-ligated Ni-Al bimetallic catalyst to realize enantioselective Ni-catalyzed aliphatic C(spsup3/sup)-H activation of formamides,

Conventional C–H alkenylation with alkynes via low-valent transition-metal catalysis occurs at the C6 or C4 position of 2-pyridone with electron-deficient C–H bonds. A bifunctional ligand-bonded Ni...
The development of transition metal-catalyzed β-C−H bond activation via highly-strained 4-membered metallacycles has been a formidable task. So far, only scarce examples have been reported to undergo β-C−H bond activation via 4-membered metalla
