Modulation of selectivity in a fluorocarbene cyclopropanation reaction: a catalytic role for bromide ion
Moss, Robert A.,Tian, Jingzhi
, p. 3419 - 3421 (2006)
Phenylfluorocarbene is diverted to phenylfluorobromomethide carbanion (PhCFBr-) by adding bromide ion. The carbanion adds to acrylonitrile leading, after expulsion of bromide, to 1-fluoro-1-phenyl-2-cyanocyclopropane.
FLP-Catalyzed Monoselective C-F Functionalization in Polyfluorocarbons at Geminal or Distal Sites
Gupta, Richa,Mandal, Dipendu,Jaiswal, Amit K.,Young, Rowan D.
, p. 1915 - 1920 (2021/04/05)
We report frustrated Lewis pair (FLP)-catalyzed monoselective C-F activation in a range of aliphatic polyfluorocarbons with equivalent geminal and distal C-F positions. This methodology can be applied to aromatic-, ether-, thioether-, and alkyl-supported fluoromethyl groups. We expand the range of FLP base partners that work with monoselective C-F activation to include sulfide. The activated products can be subsequently functionalized via SN2 substitutions, photoredox-alkylations, and Suzuki couplings.

MECHANISMS OF FREE-RADICAL REACTIONS. XX. REACTIVITY IN THE FREE-RADICAL HALOGENATION REACTIONS OF ARYLFLUOROALKANES
Dneprovskii, A. S.,Eliseenkov, E. V.
, p. 711 - 719 (2007/10/02)
The free-radical chlorination and bromination of meta- and para-substituted benzyl fluorides and 1,1-difluoro-2-phenylethane and also the chlorination of 1-fluoro-2-arylethanes by phenylchloroiodonium chloride and the bromination of meta- and para-substituted benzyl bromides were studied by the method of competing reactions.In all cases a good correlation is observed between log krel and the Brown ?+ constants.In cases where change in the reactivity in the transition from one reaction series to another is due mainly to the polar effect of the substituent whilethe selectivity is measured in relation to the polar effect direct relationships are observed between the reactivity and the selectivity.
