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.
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.

[2] This reaction was first discovered in 1947 by Alan H. Cook, Sir Ian Heilbron, and A.L Levy, and marks one of the first examples of 5-aminothiazole synthesis with significant yield and diversity in scope. [1] Prior to their discovery, 5-aminothiazoles were a relatively unknown class of compounds, but were of synthetic interest and utility.
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. [9]
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]
Benzothiazole, or more specifically 1,3-benzothiazole, is an aromatic heterocyclic compound with the chemical formula C 7 H 5 NS.It is colorless, slightly viscous liquid. Although the parent compound, benzothiazole is not widely used, many of its derivatives are found in commercial products or in
