Of them, 1,3,4-thiadiazole is the most common, appearing in such medications as cephazolin and acetazolamide. [ 1 ] [ 2 ] [ 3 ] In the Hurd-Mori reaction , an acyl hydrazone reacts with thionyl chloride or selenium dioxide to give a 1‑thia- or 1‑selena-2,3‑diazole.
1,2,3-benzothiadiazole is much less nucleophilic than naphthalene. Nitration is slow. [8] For that reason, many of its simple derivatives have been made from 2-aminothiophenols already having additional substituents. [7] 1,2,3-benzothiadiazole is a very weak base and alkylation reactions give exclusively the 3-amino quaternary salt. [9]
Bromination of 2,1,3-Benzothiadiazole is commonly performed to synthesize 4,7-dibromo-2,1,3-benzothiadiazole. This derivative is extensively used as building block in the design and synthesis of larger molecules and conductive polymers via Suzuki-Miyaura cross-coupling reactions.

Common isomers include 1,2,4-thiadiazine, 1,2,6-thiadiazine, and 1,3,4-thiadiazine. [1] Thiadiazines have gained significant interest in organic and medicinal chemistry research due to their diverse potential biological activities, including antimicrobial , anti-inflammatory , and muscle relaxant properties.
The Hurd–Mori 1,2,3-thiadiazole synthesis is a name reaction in organic chemistry that allows for the generation of 1,2,3-thiadiazoles through the reaction of hydrazone derivatives with an N-acyl or N-tosyl group reacted with thionyl chloride.
Thiazole (/ ˈ θ aɪ. ə z oʊ l /), or 1,3-thiazole, is a 5-membered heterocyclic compound that contains both sulfur and nitrogen. The term 'thiazole' also refers to a large family of derivatives. The term 'thiazole' also refers to a large family of derivatives.
