protocol was developed for the dearomatization of substituted naphthalenes, 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.
开发了一种光催化方案,通过在甲醇存在下光激发多硫化物阴离子的单电子转移诱导的自由基-极性交叉机制,用于取代萘、吲哚和相关杂芳族化合物的脱芳构化。催化转化通过多硫化物自由基阴离子和甲酸盐之间的氢原子转移来维持。
