Some derivatives of dibenzothiophene was written by Brown, Robert K.;Christiansen, Robert G.;Sandin, Reuben B.. And the article was included in Journal of the American Chemical Society in 1948.Application of 25288-76-0 This article mentions the following:
Dibenzothiophene (15 g.) in 150 ml. CCl4, treated at 0-5° with 6 g. Cl and the addition compound hydrolyzed by shaking with ice and H2O, gives 77% of the 5-oxide (I), m. 185-7°. I (15 g.), 33 ml. AcOH, and 33 ml. concentrated H2SO4 at 0° treated (15 min.) with 36 ml. HNO3 (d. 1.5), kept 30 min. at 0-5°, and poured onto ice, give 76% 3-nitrodibenzothiophene 5-oxide (II), m. 209.5-10.5°. II (10 g.) in 100 ml. AcOH, reduced with 51 g. SnCl2.2H2O in 65 ml. concentrated HCl, gives 65% 3-aminodibenzothiophene, m. 121-2.5°. II (5 g.) in 60 ml. AcOH, treated with 26 g. SnCl2.2H2O in 40 ml. 6 N HCl, kept 30 min. at 40° and 3 hrs. at room temperature, gives 91% 3-aminodibenzothiophene 5-oxide, light yellow, m. 208-9°; Ac derivative, light yellow, m. 265-7°. In the experiment, the researchers used many compounds, for example, Dibenzo[b,d]thiophen-3-amine (cas: 25288-76-0Application of 25288-76-0).
Dibenzo[b,d]thiophen-3-amine (cas: 25288-76-0) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The core structure is a part of various pharmaceutical substances and natural products. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.Application of 25288-76-0
