Recently I am researching about ALIPHATIC CARBOXYLIC-ACIDS; HYDROGEN-ATOM TRANSFER; DECARBOXYLATIVE FLUORINATION; DEOXYFLUORINATION; LIGHT; ALCOHOLS; ACTIVATION, Saw an article supported by the . Published in SCIENCE PRESS in BEIJING ,Authors: Ma, JY; Xu, WT; Xie, J. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid. COA of Formula: C7H5NO4
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.
COA of Formula: C7H5NO4. About 4-Nitrobenzoic acid, If you have any questions, you can contact Ma, JY; Xu, WT; Xie, J or concate me.
