I found the field of Chemistry very interesting. Saw the article Visible-Light-Induced Arene C(sp (2) )-H Lactonization Promoted by DDQ and tert -Butyl Nitrite published in 2020.0. Name: 6H-Benzo[c]chromen-6-one, Reprint Addresses Li, MC; Shen, ZL (corresponding author), Zhejiang Univ Technol, Coll Chem Engn, Hangzhou 310014, 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
A visible-light photocatalytic aerobic oxidative lactonization of arene C(sp (2) )-H bonds proceeds in the presence of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and tert -butyl nitrite (TBN). Under the optimized conditions, a range of 2-arylbenzoic acids is converted into the corresponding benzocoumarin derivatives in moderate to excellent yields. This method is characterized by its atom economy, mild reaction conditions, the use of a green oxidant and metal-free catalysis.
Name: 6H-Benzo[c]chromen-6-one. Bye, fridends, I hope you can learn more about C13H8O2, If you have any questions, you can browse other blog as well. See you lster.
