Abstract In this research, a simple, efficient and novel protocol is eveloped for the direct synthesis of symmetrical disulfides here using dipotassium 1,3,4-thiadiazole-2,5-bis(thiolate) as a new, low toxicity, inexpensive, stable solid and free of foul-smelling thiols for synthesize symmetric diaryl/dialkyl disulfides from aryl and alkyl halides in presence of MOF-199 and CuO nanoparticles.Significantly, using this method results in obtaining a variety of symmetrical here disulfides in moderate to excellent yields (up to 98%).
