In 2019,Nature Catalysis included an article by Zhang, Lei; Liardet, Laurent; Luo, Jingshan; Ren, Dan; Gratzel, Michael; Hu, Xile. Quality Control of 1H-1,2,3-Triazole. The article was titled 《Photoelectrocatalytic arene C-H amination》. The information in the text is summarized as follows:
A strategy to use haematite, an abundant and robust photoanode, for non-directed arene C-H amination was described. Under illumination, the photogenerated holes in haematite oxidize electron-rich arenes to radical cations, which further reacted with azoles to give nitrogen heterocycles of medicinal interest. Unusual ortho selectivity was achieved, probably due to a hydrogen-bonding interaction between the substrates and the hexafluoroisopropanol co-solvent. The method exhibited broad scope and was successfully applied to the late-stage functionalization of several pharmaceutical mols. After reading the article, we found that the author used 1H-1,2,3-Triazole(cas: 288-36-8Quality Control 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 Quality Control of 1H-1,2,3-Triazole
