methylthiolating reagent through a one-pot gram-scale operation under mild conditions. This odourless electrophilic SCD3 reagent was widely applied to react with numerous representative nucleophiles and approached various valuable SCD3 analogues with excellent levels of deuterium content (>99% D). The divergent further transformations were smoothly carried out to obtain the significant derivatives with different
<i>S</i>-(Methyl-<i>d</i><sub><i>3</i></sub>) Arylsulfonothioates: A Family of Robust, Shelf-Stable, and Easily Scalable Reagents for Direct Trideuteromethylthiolation
A family of electrophilic deuterated methylthiolating reagents, S-(methyl-d3) arylsulfonothioates, was developed in two or three steps from cheap d4-MeOH in high yields. S-(Methyl-d3) arylsulfonothioates represent a kind of powerful deuterated methylthiolating reagent and allow modular trideuteromethylthiolation with a variety of nucleophiles or electrophiles including aryl(hetero) iodides, boronic

Herein, we report the α−C−H acyloxylation of sulfides and disulfides enabled by hypervalentiodine(III) reagents via photoredoxcatalysis. The methoxylbenziodoxole derivatives serve as the hydrogen atom transfer agent, the mild oxidant, and the acyloxylation source in the reaction. External nucleophiles can also be introduced to the α−C−H of sulfides. The reaction applies to various aryl and alkyl
