Thiophenols amino

Regarding the substituent effect on reactivity of groups in positions 4 and 5 there is little information in the literature. The reactivity of halogen in position 5 seems to be increased when an amino group is present in position 2. Substitution products are easily obtained using neutral nucleophiles such as thiourea, thiophenols, and mercaptans (52-59). 

Although phenols have not participated in the Conrad-Limpach reaction under certain conditions thiophenols were not as innocent. Lee and coworkers reported mixtures of thiochromenones and quinolones from reactions of amino-thiophenols with ethyl benzoyl acetate. Amino-thiophenol 67 reacted with ethyl benzoylacetate 68 in PPA to give a mixture of thiochromenone 70 and quinolone 69 in which the quinolone predominated. 

Reactions between aziridine-2-carboxylic acids and thiols in aqueous solution have been explored by Hata and Watanabe [112]. The reactions occurred predominantly at C-2 instead of C-3 to afford 3-amino acids, with the reaction between 148 (Scheme 3.53) and thiophenol in 0.2 m sodium phosphate buffer at room tem-...

Phenyl-thiocyanat kann in alkoholischcr 2 n Schwefelsaure in Thiophenol iiberfiihrt werden (Blei-Kathode). (Nitro-phenyl)-cyan-sulfide ergeben neben etwas Amino-thio-phenol iiberwiegend dimere und heterocyclische Verbindungen (s. S. 687) ... 

In alkoholischer 2 n Sehwefelsaure werden neben 4-Amino-thiophenol hauptsachlich Dimere und Heterocyc-len erhalten F. Fighter u. F. Beck, B. 44, 3636 (1911). 

Herz A process for making o-amino thiophenols by heating the hydrochlorides of aromatic amines with sulfur monochloride at 50 to 75°C. The products are used as intermediates in the manufacture of thio-indigo dyestuffs. Invented by R. Hertz in Germany in 1914. 

I.2 Pyrrolo-benzothiazepines with other fusion modes. Thiazepine with fused pyrrole ring 250b can be prepared by condensing ortho-amino thiophenol with pyrrole carbaldehyde 249 in moderate yield (Equation (31), Section 3.1.1.4... 

The addition of anilines to styrene oxide was reported to also proceed in the presence of 10mol% 37 affording the corresponding P-amino alcohols 1-5 in yields ranging from 75% to 92% (Scheme 6.37). Additionally, urea derivative 37 (20mol% loading) was found to catalyze the addition of aniline (2.0 equiv.) to ( )-stilbene oxide (92% yield 5.9 d 30°C), the addition of thiophenol (2.0 equiv.) to 2-methoxy styrene oxide (85% 20h rt), and the alcoholysis of 4-methoxy styrene oxide with benzyl alcohol (2.0 equiv.) affording the respective P-alkoxy alcohol (82% 20h rt). 

Methylene-substituted tetrahydro-l,3-oxazine 141 underwent ring opening in response to nucleophilic attack by carboxylic acids or thiophenols to afford the A -acetyl derivatives of the corresponding 0-acyl-l,3-amino alcohols 168 or aminoalkyl sulfides 169 in high yields (Scheme 27) <2006JC0262>. 

Arylazo-Derivate von Chinoxalin, 1,4-Benzothiazin und 1,4-Benzoxazin sind durch Re-aktion von Phenylhydrazono-acetylchlorid mit 1,2-Diamino-benzol, 2-Amino-phenol und 2-Amino-thiophenol zuganglich. Die zunachst gebildeten Hydrazone konnen mit Wasser-stoffperoxid leicht zu den Arylazo-Verbindungen oxidiert werden. Die Ausbeuten fur beide Schritte sind annahernd quantitativ2 ... 

Die photochemisehe Addition von 2-Amino-thiophenol an Cyclohexen fuhrt nicht zu einem 1,4-Thiazin-Derivat, sondern zu einem spirocyclischen S,N-Acetal2.
