Thiadiazole and selenadiazole derivatives are significant organic backbones widely utilized in drugs, bioactive molecules, and functional materials. A green and efficient one-pot synthetic methodology has been developed for the fabrication of thiadiazole/selenadiazole derivatives, which involves photocatalytic induced iodine substitution, oxydic aldehyde formation, and nucleophilic addition, resulting

Synthesis of five membered heterocycles from an aryl tribromomethyl functional group is discussed. Exposing a tribromomethyl group to subsequent nucleophilic attacks by a 1,2-di-nucleophilic species promotes the cyclization of five membered heterocycles. Such heterocycles as oxadiazoles, thiadiazole, benzimidazole, benzothioazole, and benzoxazole were synthesized in moderate to good yields. Supplemental materials are available for this article.
