Tris[tetrafluoro-4-(trifluoromethyl)phenyl]borane (BTolF) was prepared by treating boron tribromide with tetrameric F3CC6F4-CuI. The F3CC6F4-CuI was generated from Fs
A Key Intermediate in Copper-Mediated Arene Trifluoromethylation, [nBu4N][Cu(Ar)(CF3)3]: Synthesis, Characterization, and C(sp2)?CF3 Reductive Elimination
Lu, Zehai,Liu, He,Liu, Shihan,Leng, Xuebing,Lan, Yu,Shen, Qilong
supporting information, p. 8510 - 8514 (2019/05/22)
The synthesis, characterization, and C(sp2)?CF3 reductive elimination of stable aryl[tris(trifluoromethyl)]cuprate(III) complexes [nBu4N][Cu(Ar)(CF3)3] are described. Mechanistic investigations, including kinetic studies, studies of the effect of temperature, solvent, and the para substituent of the aryl group, as well as DFT calculations, suggest that the C(sp2)?CF3 reductive elimination proceeds through a concerted carbon–carbon bond-forming pathway.
Preparation of organozinc compounds from 3-chloroheptafluorotoluene and zinc: The participation of C-F bonds
Krasnov, Vyacheslav I.,Vinogradov, Andrey S.,Platonov, Vyacheslav E.
, p. 168 - 170 (2007/10/03)
Organozinc compounds were obtained from 3-chloroheptafluorotoluene and Zn in DMF; the C-Cl bond is mainly involved in this reaction; the addition of SnCl2 changes the main reaction course in the direction of the participation of the C-F bond (p

Chloro- and bromo-defluorination of hexafluorobenzene and octafluorotoluene
Shipilov,Zolotkova,Igumnov
, p. 1117 - 1120 (2007/10/03)
Halo(chloro, bromo)defluorination of perfluorobenzaene and toluene efficiently occurs under the action of appropriate alkali metal halides in the presence of hexaethylguanidinium chloride in catalytic amount. The relative efficiency of halide anions and m
Perfluorozinc aromatics by direct insertion of zinc into C-F or C-CL bonds
Miller, Alexey O.,Krasnov, Vyacheslav I.,Peters, Dietmar,Platonov, Vyacheslav E.,Miethchen, Ralf
, p. 3817 - 3819 (2007/10/03)
For the first time perfluoroaromatic organozinc compounds were obtained by direct action of zinc on C-F bonds in the presence of metal salts (SnCl2, CuCl2, ZnBr2). The reactions are accelerated by ultrasound. The scope of
Regiospecific Syn Addition of (Polyfluoroaryl)copper Reagents to Fluorinated Acetylenes: Preparation and Subsequent Functionalization of Internal Vinylcopper Reagents
MacNeil, Kathryn J.,Burton, Donald J.
, p. 4411 - 4417 (2007/10/02)
(Pentafluorophenyl)copper (C6F5Cu) can be prepared from a metathesis reaction between C6F5CdX (X = Br or C6F5) and CuY (Y = Cl or Br).The arylcopper reagent undergoes a stereo- and regiospecific syn addition to fluorinated alkynes, which results in the corresponding internal alkenylcopper intermediate.This vinylcopper reagent can be subsequently functionalized with a variety of electrophiles, including aryl, alkyl, allyl, and acyl halides, to afford tetrasubstituted fluoroalkenes.The para-substituted arylcopper analogs also successfully undergo the addition reaction.
AROMATIC FLUORINE DERIVATIVES. XCI. REGIOSPECIFIC FLUORINATION OF POLYFLUORINATED AROMATIC COMPOUNDS BY SALTS OF THE DIFLUOROBROMONIUM CATION BrF2+
Bardin, V. V.,Furin G. G.,Yakobson, G. G.
, p. 879 - 884 (2007/10/02)
The reaction of polyfluorinated aromatic compounds with difluorobromium tetrafluoroborate BrF2+*BF4- leads to the products from regiospecific fluorination.Polyfluorinated derivatives of benzene, toluene, and naphthalene are fluorinated to form 1,4-cyclohexadienes, whereas pentafluoropyridine and 3-chlorotetrafluoropyridine are converted into the corresponding 1-aza-1,3-cyclohexadienes.
