Reference of 1H-1,2,3-TriazoleIn 2020 ,《Visible-Light Photoredox Catalyzed C-N Coupling of Quinoxaline-2(1H)-ones with Azoles without External Photosensitizer》 appeared in ChemCatChem. The author of the article were Sun, Mingli; Wang, Lei; Zhao, Lulu; Wang, Zhiming; Li, Pinhua. The article conveys some information:
A visible-light photoredox catalyzed C-N coupling of quinoxaline-2(1H)-ones with azoles in the absence of external photosensitizer was developed. The protocol employed com. available pyrazoles and triazoles as amination reagents and showed wide substrate scope, providing the corresponding C3-position amination products in good yields and high regioselectivity under ambient conditions. Investigations indicated that the starting materials and products can act as photosensitizers avoiding use of addnl. photocatalyst in an autocatalytic manner. In addition, 1O2 coexists with O2·- from mol. oxygen (3O2) via an energy transfer (ET) and single electron transfer (SET) process during the reaction. After reading the article, we found that the author used 1H-1,2,3-Triazole(cas: 288-36-8Reference of 1H-1,2,3-Triazole)
1H-1,2,3-Triazole(cas: 288-36-8) belongs to triazoles. Triazoles are an important group of nitrogen-containing five-membered heterocyclic scaffolds. Triazoles are core structures of several drugs and pharmaceutical agents. Triazole derivatives possess antimicrobial, antiparasitic, antidiabetic, analgesic, and anti-inflammatory properties Reference of 1H-1,2,3-Triazole
