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]
2,1,3-Benzothiadiazole has been of interest as a redox-active organic component in flow batteries owing to its favourable solubility, low reduction potential and fast electrochemical kinetics. [ 15 ] Such properties in derivatives containing this heterocycle have made it of growing interest in dyestuffs , [ 16 ] white light-emitting polymers ...
1,2,5-thiadiazole. 1,3,4-thiadiazole. Use as antifungal agents. Skeletal formula of fluconazole - an antifungal medication. The search for antifungal agents with ...
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.

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
In chemistry, dithiadiazoles are a family of heterocyclic compounds with the formula RCN 2 S 2. Two isomers have been studied: the 1,2‑dithia-3,5‑diazoles, in which the sulfur atoms are bonded to each other across the ring from the carbon atom, and the 1,3‑dithia-2,5‑diazoles, in which nitrogen and sulfur atoms alternate around the ring.
