A new approach for an efficient metal-free synthesis of 1,2,4-thiadiazoles from primary thioamides using visible light and air in the presence of eosin Y as a photoredox catalyst is reported. The protocol involves an aerobic oxidative cyclization of thioamides via the formation of C-N and C-S bonds to afford excellent yields of the products in a simple one-pot operation under mild conditions.

A highly efficient oxidative dimerization of thioamides by 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) is reported. The reaction is carried out in ClCH2CH2Cl at room temperature. The corresponding 3,5-disubstituted 1,2,4-thiadiazoles are obtained in good to excellent yields.
