N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Product Details of 1843-21-6

Synthesis of Benz-Fused Azoles via C-Heteroatom Coupling Reactions Catalyzed by Cu(I) in the Presence of Glycosyltriazole Ligands was written by Mishra, Nidhi;Singh, Anoop S.;Agrahari, Anand K.;Singh, Sumit K.;Singh, Mala;Tiwari, Vinod K.. And the article was included in ACS Combinatorial Science in 2019.Product Details of 1843-21-6 This article mentions the following:

D-Glucose-derived triazoles such as I were prepared for use as ligands in coupling and tandem coupling and cyclization reactions using CuI as catalyst and K2CO3 in DMF to yield benzoxazoles, benzothiazoles, benzimidazoles, arylaminobenzothiazoles, and benzimidazoquinazolinones. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Product Details of 1843-21-6).
