A Practical Copper Catalyzed N-Arylation of Amines Using Aryl Triazenes as Aryl Source was written by Chand, Shiv;Kumar, Saurabh;Singh, Rahul;Singh, Krishna Nand. And the article was included in ChemistrySelect in 2019.Application of 1843-21-6 This article mentions the following:
An efficient copper-catalyzed synthesis of N-arylated amines was developed via cross-coupling of amines with aryl triazenes. The methodol. was endowed with broad substrate scope, high yield and significant functional group tolerance. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Application of 1843-21-6).
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. 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.Application of 1843-21-6
