Zhu, Li-Li; Tian, Lifang; Cai, Bin; Liu, Guanglu; Zhang, Hui; Wang, Yahui published an article in 2020, the title of the article was Diamine-mediated N2-selective β-selenoalkylation of triazoles with alkenes.Name: 4-(p-Tolyl)-1H-1,2,3-triazole And the article contains the following content:

A N2-selective β-selenoalkylation of 1,2,3-triazoles with alkenes mediated by diamines has been developed. The reaction proceeds presumably via the interaction of diamines with both the triazole moiety and selenium/alkene complex to construct a U-shaped reaction intermediate. This activation mode will block the N1 position on triazoles and thus favor the N2-selective selenoamination. This stereospecific anti-addition method enables an efficient N2-selective β-selenoalkylation of 1,2,3-triazoles under mild and open-air conditions and might find applications in the synthesis of biol. active mols. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Name: 4-(p-Tolyl)-1H-1,2,3-triazole
