Formula: C7H4F2O2. I found the field of Chemistry very interesting. Saw the article Additive-Free Palladium-Catalyzed Decarboxylative Cross-Coupling of Aryl Chlorides published in 2019, Reprint Addresses Topczewski, JJ (corresponding author), Univ Minnesota Twin Cities, Dept Chem, Minneapolis, MN 55455 USA.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid.
The cross-coupling of sodium (hetero)aryl carboxylates with (hetero)aryl chlorides proceeds with 1 mol % palladium catalyst and does not require inorganic base, silver salts, or copper salts. This coupling uses two low energy partners, and the only stoichiometric byproducts are carbon dioxide and sodium chloride. The substrate scope includes less activated aryl chlorides and carboxylates (>25 examples). The palladium loading could be reduced to 0.1 mol %, and Buchwald-style precatalysts could be used.
About 2,6-Difluorobenzoic acid, If you have any questions, you can contact Daley, RA; Liu, EC; Topczewski, JJ or concate me.. Formula: C7H4F2O2
