Tetraethynylbenzo[2,1,3]thiadiazole [PDF]
Synlett, 2004 The synthesis and structural characterization of peralkynylated benzothiadiazole 2 is reported. The synthesis utilizes Vollhardt's access to hexaethynylbenzene by coupling different alkynes to tetrabromobenzo[2,1,3]thiodiazole via the Heck-Cassar-Sonogashira-Hagihara reaction.

Synthesis of novel thiadiazoles and bis-thiadiazoles from carbonothioic dihydrazide
Tetrahedron Letters, 2010Efficient syntheses of 1,3,4-thiadiazoles and bis-thiadiazoles by the reaction of hydrazonoyl halides with carbonothioic dihydrazide are reported. In addition, 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole is obtained via oxidative cyclization of bis-(substituted methylene)carbonothioic dihydrazone.
