We present a new option for metal‐free σ‐bond activation, making use of oxidized, guanidino‐functionalized aromatic compounds (GFAs). We demonstrate this new option by the homocoupling reactions of thiols and phosphines. The kinetics and the reaction pathway were studied by a number of experiments (including heterocoupling of thiols and phosphines), supported by quantum‐chemical computations. Reaction of the oxidized GFA withp‐dihydrobenzoquinone to givep‐benzoquinone shows that typical proton‐coupled electron‐transfer reactions are also possible.
