Li, Zexian published the artcileRadical Addition Enables 1,2-Aryl Migration from a Vinyl-Substituted All-Carbon Quaternary Center, Recommanded Product: Ethylbromofluoroacetate, the publication is Angewandte Chemie, International Edition (2021), 60(1), 186-190, database is CAplus and MEDLINE.
An efficient method for photocatalytic perfluoroalkylation of vinyl-substituted all-carbon quaternary centers involving 1,2-aryl migration was developed. The rearrangement reactions use fac-Ir(ppy)3, visible light and com. available fluoroalkyl halides and can generate valuable multisubstituted perfluoroalkylated compounds in a single step that would be challenging to prepare by other methods. Mechanistically, the photoinduced alkyl radical addition to an alkene leads to the migration of a vicinal aryl substituent from its adjacent all-carbon quaternary center with the concomitant generation of a C-radical bearing two electron-withdrawing groups that is further reduced by a hydrogen donor to complete the domino sequence.
