- Sequential C-H activation enabled expedient delivery of polyfunctional arenes
-
Modular construction of polyfunctional arenes from abundant feedstocks stands as an unremitting pursue in synthetic chemistry, accelerating the discovery of drugs and materials. Herein, using the multiple C-H activation strategy with versatile imidate esters, the expedient delivery of molecular libraries of densely functionalized sulfur-containing arenes was achieved, which enabled the concise construction of biologically active molecules, such as Bipenamol.

- Controllable Rh(III)-Catalyzed C-H Arylation and Dealcoholization: Access to Biphenyl-2-carbonitriles and Biphenyl-2-carbimidates
-
A controllable Rh(III)-catalyzed C-H arylation and dealcoholization of benzimidates with arylboronic esters was developed, delivering various biphenyl-2-carbonitriles and biphenyl-2-carbimidates by simply tuning the reaction conditions. This approach features high efficiency, good functional group tolerance, and easy operation. It also provides an alternative pathway to thoroughly exploit the directing group in transition-metal-catalyzed C-H activations.

- Synthesis of Functionalized Indenones via Rh-Catalyzed C-H Activation Cascade Reaction
-
An efficient and expeditious protocol for the synthesis of diverse difunctionalized indenones through rhodium-catalyzed C-H activation and multistep cascade reaction of benzimidates and alkenes has been developed. The transformation involves the cleavage and formation of multiple bonds in one pot under mild reaction conditions, and Mn(OAc)2 plays an important role in the reaction.
