A novel and an efficient method for the synthesis of 3,5-bis(acyl)-1,2,4-thiadiazoles by the oxidative cyclization of α-oxothioamides with assistance of moleculariodine has been reported. The required substrates – α-oxothioamides have been synthesized by the reaction of α-oxodithioesters with ammonium chloride and sodium acetate. The probable mechanism for the formation of products has presented.
