In 2019,Chemistry – A European Journal included an article by Pang, Yadong; Ishiyama, Tatsuo; Kubota, Koji; Ito, Hajime. Reference of 5-Fluoro-1H-indole. The article was titled 《Iridium(I)-Catalyzed C-H Borylation in Air by Using Mechanochemistry》. The information in the text is summarized as follows:
Mechanochem. has been applied for the first time to an iridium(I)-catalyzed C-H borylation reaction. By using either none or just a catalytic amount of a liquid, the mechanochem. C-H borylation of a series of heteroaromatic compounds proceeded in air to afford the corresponding arylboronates in good-to-excellent yields. A one-pot mechanochem. C-H borylation/Suzuki-Miyaura cross-coupling sequence for the direct synthesis of 2-aryl indole derivatives is also described. The present study constitutes an important milestone towards the development of industrially attractive solvent-free C-H bond functionalization processes in air. In the part of experimental materials, we found many familiar compounds, such as 5-Fluoro-1H-indole(cas: 399-52-0Reference of 5-Fluoro-1H-indole)
5-Fluoro-1H-indole(cas: 399-52-0) is a member of aromaticfluorinated building blocks. Fluorine-containing aromatics have been incorporated into crop-protection chemicals (herbicides, insecticides, fungicides). Liquid crystals, positron emission tomography, and imaging systems represent new areas where fluoroaromatics and fluoroheterocyclics have gained attention.Reference of 5-Fluoro-1H-indole
