Visible Light‐Induced Three‐Component Synthesis of S‐Aryl Dithiocarbamates via Electron Donor–Acceptor Complex Using Arylselenonium Salts

A multicomponent reaction for the efficient synthesis of S‐aryl dithiocarbamates from arylselenonium salts, CS 2 , and amines under visible light irradiation is demonstrated. This protocol enables straightforward construction of C(sp 2 )S bonds via CSe bond cleavage and allows the synthesis of diverse aryl sulfides. This three‐component process proceeds without any photocatalyst, exogenous single‐electron transfer (SET) mediator, or additional oxidant. Remarkably, this developed strategy exhibits the advantages of mild conditions, broad substrate scope, and operational simplicity. Furthermore, the byproduct dibenzoselenophene can be recovered to provide new arylselenonium salts. Mechanistic studies support the method involving a photoinduced EDA complex.
