I found the field of Chemistry very interesting. Saw the article Palladium-Catalyzed Site-Selective Benzocylization of Aromatic Acids with o-Fluoro-Substituted Diaryliodonium Salts toward 3,4-Benzocoumarins published in 2020.0. Quality Control of 6H-Benzo[c]chromen-6-one, Reprint Addresses Han, JW (corresponding author), East China Univ Sci & Technol, Key Lab Adv Mat, Inst Fine Chem, Sch Chem & Mol Engn, Shanghai 200237, Peoples R China.; Han, JW (corresponding author), East China Univ Sci & Technol, Feringa Nobel Prize Scientist Joint Res Ctr, Inst Fine Chem, Sch Chem & Mol Engn, Shanghai 200237, Peoples R China.; Han, JW (corresponding author), Chinese Acad Sci, Shanghai Hong Kong Joint Lab Chem Synth, Shanghai Inst Organ Chem, Shanghai 200032, Peoples R China.. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one
By using 2-fluoro-substituted diaryliodonium salts, a novel benzocylization has been accomplished for the synthesis of 3,4-benzocoumarin derivatives via a cascade of ortho-arylation and defluorination in the presence of palladium catalysts. The reaction exhibits a broad compatibility of readily available aromatic acids with an excellent level of site-selectivity. Mechanistic investigations revealed a unique reactivity of carboxylic acid directed arylation by followed nucleophilic substitution of aromatic fluoride in the present system.
