Name: 4-Nitrobenzoic acid. I found the field of Chemistry very interesting. Saw the article Predictable site-selective radical fluorination of tertiary ethers published in 2020.0, Reprint Addresses Xie, J (corresponding author), Nanjing Univ, BioMed Innovat Ctr,Sch Chem, State Key Lab Coordinat Chem, Jiangsu Key Lab Adv Organ Materials,Chem, Nanjing, Peoples R China.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid.
In this communication, we disclose the first example of metal-free and site-selective radical fluorination of readily available tertiary alkyl ethers, enabled by synergistic photocatalysis and organocatalysis. This catalytic combination allows for exclusive fluorination of tertiary C-O bonds under mild conditions even in the presence of competing reaction sites. The excellent functional group tolerance affords valuable access to sterically hindered alkyl fluorides through late-stage modification of complex molecules. The successful use of tertiary alkyl ethers in radical fluorination enhances the structural diversity of aliphatic fluorides that can be derived from naturally abundant alcohols.
