BEITRAEGE ZUR CHEMIE DES BROMTRIFLUORIDS 1.TEIL PENTAFLUORPHENYLBROM(III)DIFLUORID UND -BIS(TRIFLUORACETAT)

BrF3 reacts with C6F5SiF3 to form C6F5BrF2, a volatile, colourless, and thermally stable solid, which melts at 35 - 36 deg C without decomposition.Its chemical and spetroscopic properties are in contrast to the product described by Sams .The reactivity

Bis(perfluoroorganyl)bromonium salts [(RF)2Br]Y (RF = aryl, alkenyl, and alkynyl)

Bromonium salts [(RF)2Br]Y with perfluorinated groups RFC6F5, CF3CFCF, C 2F5CFCF, and CF3C≡C were isolated from reactions of BrF3 with RFBF2 in weakly coordinating solvents (wcs) like CF3CH2CHF2 (PFP) or CF3CH2CF2CH3 (PFB) in 30-90% yields. C6F5BF2 formed independent of the stoichiometry only [(C6F5)2Br][BF 4]. 1:2 reactions of BrF3 and silanes C6F 5SiY3 (Y = F, Me) ended with different products - C 6F5BrF2 or [(C6F5) 2Br][SiF5] - as pure individuals, depending on Y and on the reaction temperature (Y = F). With C6F5SiF3 at ≥-30 °C [(C6F5)2Br][SiF5] resulted in 92% yield whereas the reaction with less Lewis acidic C 6F5SiMe3 only led to C6F 5BrF2 (58%). The interaction of K[C6F 5BF3] with BrF3 or [BrF2][SbF 6] in anhydrous HF gave [(C6F5) 2Br][SbF6]. Attempts to obtain a bis(perfluoroalkyl) bromonium salt by reactions of C6F13BF2 with BrF3 or of K[C6F13BF3] with [BrF2][SbF6] failed. The 3:2 reactions of BrF3 with (C6F5)3B in CH2Cl2 gave [(C6F5)2Br][(C6F 5)nBF4-n] salts (n = 0-3). The mixture of anions could be converted to pure [BF4]- salts by treatment with BF3·base.

Contributions to the chemistry of brominetrifluoride. Part 2. Bis(pentafluorophenyl)bromonium cations with weak nucleophilic fluoroelementate anions

BrF3 reacts with MII(C6F5)2 (M = Zn, Cd, Hg) in organic solvents independent of the stoichiometry under formation of C6F5BrF2. Bromonium compounds [(C6F5)2Br]+ [EFn+l]- (E = Sb, As, B) are formed in equimolar reactions if additionally Lewis-acids EFn are present. [(C6F5)2Br]+ [BF4]- results in quantitative yield independent of the stoichiometry of substrates if BrF3 reacts with the Lewis-acidic aryl transfer reagent (C6F5)2BF. The molecular structure of the bromonium compounds [(C6F5)2Br]+ [BF4]- and [(C6F5)2Br]+ [AsF6]- can be interpreted in terms of two asymmetric hypervalent bonds at bromine(III). In solution the electrophilicity of Br(III) in [(C6F5)2Br]+ [EFn+l]- is responsible for the strong dependence of the 19F NMR shift values from the nucleophilicity of the solvent. Gauthier-Villars.
