Arynes as Radical Acceptors: TEMPO‐Mediated Cascades Comprising Addition, Cyclization, and Trapping
The application of arynes as radical acceptors is described. The stable radical TEMPO (2,2,6,6‐tetramethyl piperidine 1‐oxyl) is shown to add to various ortho‐substituted benzynes generating the corresponding aryl radicals which engage in 5‐exo or 6‐endo cyclizations. The cyclized radicals are event...
