Photosensitized Imino-Thiocyanation of Alkenes

A metal-free photosensitized 1,2-imino-thiocyanation of olefins has been established by using the easily accessible bifunctional reagent <i>S</i>-cyano-<i>N</i>-(diphenylmethylene) thiohydroxylamine. A wide range of olefins were successfully transformed into the corresponding β-iminothiocyanates in moderate to high yields. This protocol stands out for its metal-free nature, broad substrate compatibility, and high atom and step economy, providing an effective strategy for assembling β-amino thiocyanate-containing scaffolds.
