The emergence of sulfoxide and iodonio-based redox arylation as a synthetic tool

This digest highlights the emergence of the directed metal-free arylation approach employing simple sulfoxide and hypervalent aryliodane. These new processes are characterized by an unusual, and synthetically attractive, retention of the reduced −SR and iodine fragment ortho to the newly formed CC bond. The ultimate goal is to (a) highlight the synthetic potential of the approach; and (b) offer, for the first time, a unified vision of the two processes.
