protocol was developed for the dearomatization of substitutednaphthalenes, indoles, and related heteroaromatic compounds through a radical-polar crossover mechanism induced by single-electron transfer from photoexcited polysulfide anions in the presence of methanol. The catalytic turnover is maintained by hydrogen-atom transfer between polysulfide radical anions and formate.
