2-Aminothiophenol is a precursor to benzothiazoles, some of which are bioactive or are commercial dyes. Isomers of aminothiophenols include 3-aminothiophenol and 4-aminothiophenol. 2-Aminothiophenol can prepared in two steps, starting with the reaction of aniline with carbon disulfide followed by hydrolysis of the resulting ...
Aminothiophenol may refer to: 2-Aminothiophenol; 3-Aminothiophenol [Wikidata] 4-Aminothiophenol This page was last edited on 14 May 2022, at ...
2-Aminophenol has a variety of uses. As a reducing agent, it is marketed under the names of Atomal and Ortol to develop black-and-white photographs. [3] 2-Aminophenol is an intermediate in the synthesis of dyes. It is particularly useful in yielding metal-complex dyes when diazotized and coupled to a phenol, naphthol, or other aromatic or ...

Hydrolysis of this Herz salt give the corresponding sodium thiolate, which can be further converted to the 2-aminothiophenol. [1] Herz-reaction. The 2-aminothiophenols are suitable for diazotization, giving benzothiadiazoles. [2] Instead the sodium 2-aminothiophenolate can be converted to a 1,3-benzothiazole. Herz-reaction application
Goldberg reaction completed the formation of the phenothiazine ring and gave N,N-dimethyl-10H-phenothiazine-2-sulfonamide [1090-78-4] (6). Attachment of the sidechain by sodamide reaction with 1-(3-Chloropropyl)-4-Methylpiperazine [104-16-5] ( 7 ) completes the synthesis of Thioproperazine ( 8 ), respectively.
[2] Benzo-1,2-3-dithiazolium salts can be prepared by the Herz reaction, which entails the reaction of an aniline with disulfur dichloride. Hydrolysis of this "Herz salt" gives the corresponding sodium thiolate, which can be further converted to the 2-aminothiophenol. [3] Herz-reaction. Appel's salt is an example of a 1,2,3-dithiazolium. [4]
The traditional route is the reaction of 2-aminothiophenol and carbon disulfide: C 6 H 4 (NH 2)SH + CS 2 → C 6 H 4 (NH)SC=S + H 2 S. This method was developed by the discoverer of the compound, A. W. Hoffmann. Other routes developed by Hoffmann include the reactions of carbon disulfide with 2-aminophenol and of sodium hydrosulfide with ...
