late-stage arylation of N–S bonds in sulfonamides has been developed with using readily available imines as sulfonyl radical source. Diverse complex sulfones could be synthesized by prefunctionalizaiton and subsequent N–S bond arylation, demonstrating the advantages of using sulfonamides as sulfonylation reagents. Additionally, the mechanism research revealed that probably both EDA complex chemistry and photoredox

A simple and ubiquitously present group, free amine, is used as a directing group to synthesize axially chiral biaryl compounds by PdII -catalyzed atroposelective C-H olefination. A broad range of axially chiral biaryl-2-amines can be obtained in good yields with high enantioselectivities (up to 97 % ee). Chiral spiro phosphoricacid (SPA) proved to be an efficient ligand and the loading could be reduced
