The Pd-catalyzed α-arylation of carbonylcompounds with simple arenes enabled by site-selective thianthrenation has been demonstrated. This one-pot process using thianthrenium salts as the traceless arylating reagents features mild conditions and a broad substrate scope. In addition, this protocol could also tolerate the heterocyclic carbonylcompounds and complex bioactive molecules, which is appealing

Set the ace(tone): A palladium catalyst derived from the bidentate XantPhos ligand and Pd(OAc)2 has enabled broadly applicable mono‐α‐arylations of acetone to be performed with air‐ and moisture‐stable arylimidazolylsulfonates as most user‐friendly electrophiles (see scheme).
