Fluorination with XeF2. 40. The Important Role of ?-Bond Disruption in Fluorine Addition to Phenyl-Substituted Alkenes
Stavber, Stojan,Sotler, Tjasa,Zupan, Marko,Popovic, Arkadij
, p. 5891 - 5894 (1994)
Ionization potentials (IP) for 11 mono- and α,α-diphenyl-substituted acyclic and cyclic alkenes 1-11 were measured under the same conditions, using a mass spectrometric technique and applying electron impact ionization.The values, ranging from 8.68 eV for

The TeF5 group is significantly underexplored as a highly fluorinated substituent on an organic framework, despite it being a larger congener of the acclaimed SF5 group. In fact, only one aryl-TeF5 compound (phenyl-TeFsub
Phenyltetrafluorotelluromethoxide - A new fluorinating reagent for olefins
Lermontov,Bahtin
, p. 722 - 723 (2007/10/03)
Phenyltetrafluorotelluromethoxide fluorinates olefins to form 1,2-difluorides. The reaction with styrene afforded 1-fluoro-4-phenyl-1,2-dihydronaphthalene as the main product.

Lermontov, Sergei A.,Zavorin, Sergei I.,Bakhtin, Ilya V.,Pushin, Alexei N.,Zefirov, Nikolai S.,Stang, Peter J.
, p. 75 - 83 (2007/10/03)
Phenyselenium trifluoride, PhSeF3 (PSTF) either oxidatively difluorinates or selenofluorinates olefins, depending on their structures. The pentafluorides PhSeF5 and PhTeF5 appear to be effective difluorinating reagents, af
FLUORINATING PROPERTIES OF PhTeF5 AND PhSeF5 TOWARDS C=C BOND
Lermontov, Sergei A.,Zavorin, Sergei I.,Bakhtin, Ilya V.,Zefirov, Nikolai S.,Stang, Peter J.
, p. 283 - 286 (2007/10/02)
Phenylselenium pentafluoride and phenyltellurium pentafluoride react with olefins affording appropriate 1,2-difluorides under mild conditions.Key words: Phenylselenium pentafluoride, phenyltellurium pentafluoride, xenon difluoride, olefins, difluorination, electrophilic addition.
Oxidative fluorination in amine-HF mixtures
Meurs,Eilenberg
, p. 705 - 714 (2007/10/02)
The selective electrochemical fluorination of alkenes, phenanthroline, naphthalene and chlorobenzene in neat amine-HF mixtures is described, together with the chemistry of 4,4-difluorocyclohexadienone.
Reaction of epoxides with diethylaminosulfur triflouride
Hudlicky, Milos
, p. 373 - 384 (2007/10/02)
Diethylaminosulfur triflouride (DAST) reacts with epoxides (oxiranes) to form geminal diflourides, vicinal diflourides, and bis(2-fluoroalkyl) ethers. Thus cyclopentene oxide gave cis-1,2-difluorocyclopentane and bis(2-fluorocyclopentyl) ether; cyclohexene oxide gave cis-1,1-difluorocyclohexane and bis(2-fluorocylohexyl) ether; styrene oxide gave 1,1-difluoroethylbenzene and 1,2-difluoroethylbenzene; and cis- and trans-stilbene oxides gave mixtures of meso- and racemic 1,2-difluoro-1,2-diphenylethanes together with 1,1-difluoro-2,2-diphenylethane resulting from a rearrangement. Cyclooctene oxide and cyclohexene sulfide do not react appreciably under the same conditions.
Reaction of Fluoroxytrifluoromethane with Ring-Substituted Styrenes: A Structure-Reactivity Study
Levy, Joseph B.,Sterling, Doreen M.
, p. 5615 - 5619 (2007/10/02)
The reaction of fluoroxytrifluoromethane (FTM) with a group of ring-substituted styrenes has been studied.Reaction products have been determined, and relative rates for addition to the double bond have been measured by a competition method.The data give a straight line when plotted as log (k/kH)vs.Hammett ? values with a ρ of -2.48.A similar plot vs. ?+ gave less satisfactory agreement with linearity and a ρ of 2.18.A mechanism is proposed in which a spin-paired free-radical pair is formed that is converted by electron transfer into an ion pair.
