Crucial radicals: The aniline‐mediated photochemical disulfide bond cleavage of linear or cyclic disulfide compounds (RSSR; see scheme) is shown to initiate by a photoinduced electron transfer from the excited state of aniline as well as by reduction with solvated electrons produced by the direct photoionization of aniline. The crucial intermediates in the disulfide cleavage are the disulfide radical anions.
