SDS of cas: 2005-10-9. Published in GEORG THIEME VERLAG KG in STUTTGART ,Authors: Wang, YQ; Wang, SP; Chen, BJ; Li, MC; Hu, XQ; Hu, BX; Jin, LQ; Sun, N; Shen, ZL. 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.
SDS of cas: 2005-10-9. 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.
