and a simple sulfinate transfer reagent. The reactions proceed by formation of an intermediate benzylic sulfinate, formed in situ, and deliver di(hetero)arylmethane products. The reactions use only commercial components, and no stoichiometric metal reductant is needed.

Aliphatic strained rings can be (hetero)arylated through a decarboxylative cross-electrophile coupling. The keys to this advance are: 1) a new ligand that enables tolerance of a variety of strained ring classes and 2) electronic tunability of redox-active esters to control the rate of radical generation.
