Yu, Jiajia published the artcileDistal Functional Group Migration for Visible-light Induced Carbo-difluoroalkylation/monofluoroalkylation of Unactivated Alkenes, COA of Formula: C4H6BrFO2, the publication is Advanced Synthesis & Catalysis (2018), 360(4), 744-750, database is CAplus.
A general and practical protocol for elusive carbo-difluoroalkylation/monofluoroalkylation of unactivated alkenes HOCR1R2(CH2)2CH:CH2 (R1 = n-pentyl, 2-thienyl, Ph, etc.; R2 = CHO, 2-benzothiazolyl, PhCC, etc.) with fluoroalkyl bromides R3R4CFBr (R3 = EtO2C, R4 = H, F; R3 = Br, PhSO2, morpholin-4-ylcarbonyl, R4 = F) based on the distal functional group migration is described. A portfolio of functional groups including heteroaryl, imino, formyl, and alkynyl groups showcase the migratory aptitude. In combination with visible-light photocatalysis, a broad range of di- and mono-fluorinated alkyl ketones R1C(O)(CH2)2CHR2CH2CFR3R4 were readily obtained in synthetically useful yields under mild reaction conditions.
