摘要：
A single-step visible light mediated synthesis of beta-hydroxydithioacetals via oxidative coupling of terminal alkynes with thiophenol is reported. Compared to other multistep strategies, this work presents a rare tandem introduction of disulfides and a hydroxy group at the beta-position in one pot. The reaction is enabled by aerial oxidation, features high efficiency and mild conditions, and is extendable to both aliphatic and aromatic alkynes.
