DDQ-promoted C-S bond formation: synthesis of 2-aminobenzothiazole derivatives under transition-metal-, ligand-, and base-free conditions was written by Wang, Rui;Yang, Wen-juan;Yue, Liang;Pan, Wei;Zeng, Hong-yao. And the article was included in Synlett in 2012.Recommanded Product: N-Phenylbenzo[d]thiazol-2-amine This article mentions the following:
A transition-metal-free method for the intramol. S-arylation of o-halobenzothioureas via DDQ-mediated leading to the 2-aminobenzothiazole derivatives, e.g., I (R = H, Me, MeO, F; R2 = H, Me, MeO, Cl, Br), is reported. The reactions are performed at room temperature under ligand- and base-free conditions with good to excellent yields. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Recommanded Product: N-Phenylbenzo[d]thiazol-2-amine).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Recommanded Product: N-Phenylbenzo[d]thiazol-2-amine
