Visible Light-Induced Photocatalytic C?H Perfluoroalkylation of Quinoxalinones under Aerobic Oxidation Condition

Article abstract of DOI:10.1002/adsc.201900885

An efficient approach using a photocatalytic strategy for C?H perfluoroalkylation of quinoxalinones under aerobic oxidation condition has been developed. Such transformation employs readily available sodium perfluoroalkanesulfinates as perfluoroalkylation reagents and demonstrates good functional group compatibility, affording corresponding products in moderate to good yields. Compared with previous procedures, this protocol uses oxygen as oxidant, and avoids the use of external additive. A radical mechanism is involved in this perfluoroalkylation reaction.
