In summary, we have demonstrated a complementary electrochemical method by using diverse nucleophilic sulfinates to empowermeta-sulfonylation of pyridines through a redox-neutral dearomatization-rearomatization strategy. It so far represents a sole example of using nucleophilic partners to functionalize pyridin...
In summary, we have developed dehydrogenative β-sulfonylation reactions using amines and aryl sulfonyl chlorides via intermolecular HAT and C−S cross-coupling process at room temperature. Furthermore, we demonstrated the direct generation of two distinct Pd-radical hybrid species and their capability ...

(d) This work: SO2-insertion induced asymmetric oxysulfonylation to quaternary carbon stereocenters (color online). Advances in sulfur dioxide insertion chemistry have greatly increased the versatility ...
Herein we report a novel approach for the direct C–H-sulfonylation of N-heteroaromatics via N-activation with triflic anhydride (Tf2O), base-mediated addition of a sulfinate salt and subsequent rearomatization through trifluoromethanesulfinate elimination. This operationally simple one-pot protocol ...
A highly efficient and eco-friendly method has been developed for the synthesis of allyl sulfones using Morita–Baylis–Hillman (MBH) adducts and thiosulfonates under mild conditions. The Cs2CO3-promoted radical sulfonylation provided a series of allyl sulfones in good to high yields with high ster...

An additive‐ and transition metal‐free perfluoroalkanesulfonylation of alkynyl(phenyl)iodonium tosylates with sodium perfluoroalkanesulfinates (RfnSO2Na) is described. The poorly nucleophilic RfnSO2Na reacted with alkynyl(phenyl)iodonium salts in dichloromethane at room temperature under a nitrogen ...
Visible-light-promoted hydroxysulfonylation of the C–C double bond of alkylidenecyclopropanes (ACPs) with conservation of the cyclopropyl ring has been developed. The difunctionalization reaction exhibits a broad substrate scope with excellent functional group compatibility, affording a series of ...
