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.

Directed activation of C–H bonds usually occurs through 5-membered metallacycles, which poses limitations of regiochemistry. Herein, the authors use a phosphine oxide-ligated Ni−Al bimetallic catalyst to enable β-C−H bond-involved hydroarylati

Allylic amines are versatile building blocks in organic synthesis and exist in bioactive compounds, but efficient catalytic systems for hydroaminoalkylation of alkynes are needed. Here, the authors report a late transition metal‐catalyzed hydroamin

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

Ligands play a critical role in promoting transition-metal-catalyzed C–H activation reactions. However, owing to high sensitivity of the reactivity of C–H activation to metal catalysts, the development of effective ligands has been a formidable c

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

Co-catalyzed C–H functionalization has received great attention due to the high earth abundance, low biotoxicity, and unique reactivity of cobalt; enantioselective control of these reactions has been a formidable challenge. Various efficient strate

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
