On November 15, 2019, Shu, Wen-Ming; Zhang, Xun-Fang; Zhang, Xiang-Xiang; Li, Min; Wang, An-Jing; Wu, An-Xin published an article.Related Products of 5301-96-2 The title of the article was Metal-Free Cascade [4+1] Cyclization Access to 4-Aryl-NH-1,2,3-Triazoles from N-Tosylhydrazones and Sodium Azide. And the article contained the following:

A mol. iodine mediated coupling cyclization reaction for the synthesis of 4-aryl-NH-1,2,3-triazoles I (R1 = C6H5, 2-CH3C6H4, 3-CH3OC6H4, etc.; R2 = H, CH3, C6H5) has been developed from N-tosylhydrazones and sodium azide. This metal-free cascade [4+1] cyclization reaction could rapidly synthesize valuable compounds via a sequential C-N and N-N bond formation. Mechanistic studies demostrate that the nitrogen-atoms of the 1,2,3-triazoles are not entirely from sodium azide. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Related Products of 5301-96-2

The Article related to aryl triazole preparation metal free, tosylhydrazone sodium azide mol iodine cyclization, Heterocyclic Compounds (More Than One Hetero Atom): Other 5-Membered Rings, Two Or More Hetero Atoms and other aspects.Related Products of 5301-96-2

Hui, Rongrong; Zhao, Mina; Chen, Ming; Ren, Zhihui; Guan, Zhenghui published an article in 2017, the title of the article was One-Pot Synthesis of 4-Aryl-NH-1,2,3-Triazoles through Three-Component Reaction of Aldehydes, Nitroalkanes and NaN3.Synthetic Route of 5301-96-2 And the article contains the following content:

A one-pot three-component reaction of aldehydes, nitroalkanes and NaN3 for the synthesis of NH-1,2,3-triazoles such as I [R1 = Ph, 2-furyl, 3-indolyl, etc.; R2 = H, Me, Et, CO2Et] was developed. The reaction provided a safe, efficient and step-economic approach for the synthesis of various NH-1,2,3-triazoles in good to excellent yields. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Synthetic Route of 5301-96-2
