An approach for the synthesis of selenaheterocycles starting from aryl diazonium salts was developed. The one-pot process and subsequent visible-light-mediated silver-catalyzed cyclization enabled the synthesis of selenaheterocycles in the absence of a photocatalyst. The reactions were carried out under mild conditions without the use of toxic or sensitive reagents. (Figure presented.).

The reaction of aromatic and heterocyclic lithio derivatives with elemental selenium, followed by dimethylthiocarbamyl chloride, gives highly crystalline and readily purified Se-aryl N,N-dimethylselenothiocarbamates.Alkaline hydrolysis of the latter, followed by ferricyanide oxidation, affords diselenides.Overall yields and purity of the diselenides are superior to those obtained by the standard direct selenation-oxidation method.
