Synthesis of new thioindigo derivatives containing SH groups at the terminal positions of the side chains, intramolecular SâS bond formation by a photo-redox reaction, and thermal bond scission due to reducing ability of the leuco form are described.
介绍了在侧链末端位置含有 SH 基团的新硫代靛蓝衍生物的合成、通过光氧化还原反应形成的分子内 SâS 键,以及由于白基形式的还原能力而导致的热键断裂。
