Palladium–Catalyzed α‐Arylation of Sulfoxonium Ylides with Aryl Thianthrenium Salts via C‐S and C‐H Bond Activation

Diverse α‐aryl α‐carbonyl sulfoxonium ylides were efficiently synthesized in yields ranging from moderate to high via a palladium‐catalyzed α‐arylation of sulfoxonium ylides with aryl thianthrenium salts. The reactions proceeded smoothly via C‐S and C‐H bond functionalization, exhibiting broad substrate scope and good compatibility to various functionalities. In addition, the scale‐up synthesis could be achieved, and the one‐pot protocol commencing from the use of simple arene as the precursor of aryl thianthrenium salt could also be accomplished.
