Facile synthesis of N2-substituted-1,2,3-triazole from aryl ethynylene and azide via a one-pot two-step strategy was written by Guan, Cong;Ji, Jian;Li, Zi;Wei, Qinghua;Wu, Xiang;Liu, Shunying. And the article was included in Tetrahedron in 2022.Electric Literature of C6H4S This article mentions the following:
An efficient one-pot two-step synthetic strategy to access highly selective N2-substituted-1,2,3-triazole from aryl ethynylenes, azides and furan has been developed via a radical transformation. 17 Examples of aryl ethynylene with various substituents were converted into their corresponding functionalized N2-substituted-1,2,3-triazole derivatives in good yields. In the experiment, the researchers used many compounds, for example, 3-Ethynylthiophene (cas: 67237-53-0Electric Literature of C6H4S).
3-Ethynylthiophene (cas: 67237-53-0) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The core structure is a part of various pharmaceutical substances and natural products. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Electric Literature of C6H4S
