2- Aminobenzene thiol

The latter is also prepared by condensation of 2-cyanomethyl-1,3-benzothiazole (184 R=H)[from 2-aminobenzene thiol and malono-nitrile] with aromatic aldehydes in the presence of NEt at room temperature. In THF at reflux (184 R=H) and ArCHO/NEt yield the fused system (185). ... 

Analogously, 4-acyl-l,2-dimethylphenothiazin-3-ones have been synthesized by the reaction of 2-aminobenzene-thiol and 2-acyl-5,6-dimethyl-1,4-benzoquinones (81JHC645). This method was also used to prepare hydroxyphenothiazines, hard to obtain in other ways. Thus, hydroxyphenothiazines such as 85 have been prepared... 

Ivlixed inhibitors may simultaneously affect both anodic and cathodic processes. A mixed inhibitor is usually more desirable because its effect is all-encompassing, covering corrosion resulting from chloride attack as well as that due to microcells on the metal surface. Mixed inhibitors contain molecules in which electron density distribution causes the inhibitor to be attracted to both anodic and cathodic sites. They are aromatic or olefinic molecules with both proton-forming and electron acceptor functional group such as NH or SH, as in aminobenzene thiol. Mixed inhibitors are similarly used at l-2 > addition rates [50],... 

An intermediate has been isolated from the reaction between o-aminobenzene-thiol and dimethyl cyanimidodithioate (see Vol. 3, pp. 617, 618) this yields bis(benzothiazol-2-yI)amine, thus further elucidating the mechanism. ...
