Unsymmetrical Diaryl Sulfones and Aryl Vinyl Sulfones Through Palladium-Catalyzed Coupling of Aryl and Vinyl Halides or Triflates with Sulfinic Acid Salts.
— The title method, employing Pd2(dba)3/Xantphos as catalyst, is a useful route to sulfones having a wide range of substituents, except for aryl halides or triflates bearing
substituents close to the oxidative addition side. In many cases, the presence of Bu4NCl
is crucial for the success of the reaction. — (CACCHI*, S.; FABRIZI, G.;
