Rearrangement of phenylethenes on reaction with iodine-xenon difluoride

(matrix presented) Phenyl-substituted ethenes react with iodine and xenon difluoride to provide difluorinated products. Iodofluoro intermediates react with xenon difluoride to produce transient iodine difluoride species that lose IF and F- and produce carbocations.

Effect of Alkene Structure on the Course of Reactions with XeF2 and CsSO4F

XeF2 reacted at room temperature in dichloromethane in the presence of HF with triphenylethene, 9-benzylidenefluorene and tetraphenylethene to form vicinal difluorides in high yield, the relative reactivities being in the following order: 1,1-diphenylethe

N-Fluorobisimides: Reactions with Some Olefins via α-Fluoro Carbocationic Intermediates

N-Fluorobisimides are a new class of electrophilic fluorinating agents.Reaction of (CF3SO2)2NF (1) with olefins gave various products, depending on the reaction conditions and the structure of the substrate.In solvents of higher nucleophilicity such as H2O, acetic acid, aqueous HCl, and (HF)nPy, α-fluorohydrins and their acetates, α,β-chlorofluoro- and α,β-difluoroalkanes were obtained.In acetic acid, trans-stilbene and tetraphenylethylene produced the rearranged, nonfluorinated aldehyde and ketone.Evidence is presented for the reactions proceeding via a one-electron transfer mechanism involving α-fluorocarbocationic intermediates.
