Recently I am researching about O BOND FORMATION; CARBOXYLIC-ACIDS; BENZOCOUMARINS; LACTONIZATION; CYCLIZATION; ACCESS; NIS, Saw an article supported by the JSPS KAKENHIMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) [JP18K05118]. Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Nakamura, M; Togo, H. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one.

Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.
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.. Category: esters-buliding-blocks
