Disulfides are versatile catalysts. They can be photocatalysts, hydrogen atom transfer (HAT) catalysts, cocatalysts, or initiators in photocatalytic reactions. Under photoirradiation, organic disulfides can be easily cleaved into free thiyl radicals (RS) and can reversibly add to unsaturated multiple bonds to catalyze a variety of functionalization reactions under mild conditions. In photoredox catalysis reactions, an excellent electron transfer ability and excellent radical properties also made these thiyl radicals powerful HAT catalysts. They have increasingly been proven useful in various types of organic photoreactions, such as cyclizations, anti-Markovnikov additions, aromatic olefin carbonylations, isomerizations, etc. They are a class of green, economic, mild, and chemoselective radical catalysts that deserve more attention. The present review highlights the recent progress in the field of disulfide-catalyzed and -cocatalyzed photocatalytic reactions for different reaction types.

二硫化物催化和共催化光反应概述。

二硫化物是通用催化剂。它们可以是光催化反应中的光催化剂,氢原子转移(HAT)催化剂,助催化剂或引发剂。在光辐照下,有机二硫化物可以很容易地裂解成游离的噻吩基(RS ),并且可以在温和条件下可逆地加成不饱和多个键,以催化各种官能化反应。在光氧化还原催化反应中,出色的电子转移能力和出色的自由基性能也使这些硫代自由基成为了强大的HAT催化剂。越来越多地证明它们可用于各种类型的有机光反应中,例如环化反应,抗马尔可夫尼可夫添加物,芳族烯烃羰基化反应,异构化反应等。它们是一类绿色,经济,温和和化学选择性的自由基催化剂,应引起更多关注。本综述着重说明了在二硫化物催化和共催化光催化反应领域中针对不同反应类型的最新进展。
