In the presence of an equimolar amount of P(NEt₂)₃, polyfluorophenyl bromides react with alkylhalosilanes, -germanes, -stannanes, and -plumbanes to give the corresponding phenyl(alkyl) derivatives of these elements plus a phosphonium salt. Electron-donating groups in the 4-position of the polyfluorophenyl bromide slow the reaction, whereas electron-accepting groups accelerate it.

Benz, Sebastian published the artcileCatalysis with Pnictogen, Chalcogen, and Halogen Bonds, Recommanded Product: Trimethyl(perfluorophenyl)silane, the publication is Angewandte Chemie, International Edition (2018), 57(19), 5408-5412, database is CAplus and MEDLINE.

Halogen- and chalcogen-based ¦Ò-hole interactions have recently received increased interest in non-covalent organocatalysis. However, the closely related pnictogen bonds have been neglected. In this study, authors introduce conceptually simple, neutral, and monodentate pnictogen-bonding catalysts. Solution and in silico binding studies, together with high catalytic activity in chloride abstraction reactions, yield compelling evidence for operational pnictogen bonds. The depth of the ¦Ò holes is easily varied with different substituents. Comparison with homologous halogen- and chalcogen-bonding catalysts shows an increase in activity from main group VII to V and from row 3 to 5 in the periodic table. Pnictogen bonds from antimony thus emerged as by far the best among the elements covered, a finding that provides most intriguing perspectives for future applications in catalysis and beyond.

Liebing, Phil published the artcileSupramolecular Aggregation of Perfluoroorganyl Iodane Reagents in the Solid State and in Solution, HPLC of Formula: 1206-46-8, the publication is European Journal of Organic Chemistry (2018), 2018(27-28), 3771-3781, database is CAplus.

The crystal structures of different perfluoroorganyl iodanes are described, including those of four new benziodoxole derivatives with R_F = n-C₃F₇, n-C₄F₉, n-C₈F₁₇, and C₆F₅. In all of the compounds, the iodine atom shows significant Lewis acidity, and the fourth coordination site is readily filled by secondary bonding interactions to produce square-planar coordination. Although this geometry is a good model for benziodoxoles, benziodoxolone derivatives tend to aggregate further through addnl. weak I¡¤¡¤¡¤O or I¡¤¡¤¡¤aryl contacts. The different interactions lead to the formation of various assemblies with different dimensions in the solid state. The protonation of the reagents results in the formation of entirely different supramol. structures, which are supported by hydrogen bonding. The structural features of the reagents in the solid state reflect well their behavior in solution, and the I-C(R_F) bond is influenced by the coordination of Lewis basic solvents to the iodine atom and by hydrogen bonding with protic solvents. These solvent effects are more pronounced for reagents containing the trifluoromethyl fragment than for derivatives with longer R_F chains.

Kremer, Silke published the artcileSilver Compounds in Synthetic Chemistry. Part 8. Complexes of Perfluoroorgano Silver(I) Derivatives with 4-Dimethyl-aminopyridine (DMAP), Recommanded Product: Trimethyl(perfluorophenyl)silane, the publication is Zeitschrift fuer Anorganische und Allgemeine Chemie (2014), 640(12-13), 2458-2462, database is CAplus.

Attempted syntheses of AgR_f¡¤DMAP were performed using the established route starting from AgF and Me₃SiR_f (R_f = CF₃, C₂F₅, C₆F₅) followed by the addition of DMAP. Unexpectedly, reactions with perfluoroalkylsilver(I) derivatives yielded products, which underwent known equilibrium, while exclusively the pentafluorophenyl derivative exhibits its zwitterionic nature in solution and in the solid state. Moreover, both perfluoroalkyl derivatives investigated decomposed slowly but more or less selectively even at -20¡ã in solution: AgC₂F₅¡¤DMAP mainly into AgOCOCF₃ (probably under the influence of moisture) and AgCF₃¡¤DMAP mainly into the unprecedented derivative 3-trifluoromethyl-4-dimethylaminopyridine. The mol. structure of AgC₆F₅¡¤DMAP was elucidated showing a twist arrangement of the aromatic rings quite unusual for linear coordinated species.

Wang, Xiu published the artcileControllable Single and Double Difluoromethylene Insertions into C-Cu Bonds: Copper-Mediated Tetrafluoroethylation and Hexafluoropropylation of Aryl Iodides with TMSCF₂H and TMSCF₂Br, Related Products of catalysis-chemistry, the publication is Journal of the American Chemical Society (2022), 144(27), 12202-12211, database is CAplus and MEDLINE.

The selective difluoromethylene insertion into a C-Cu bond is a challenging task and is currently limited to either a single CF₂ insertion into CuCF₃ or double CF₂ insertions into CuC₆F₅ (or (Z)-CF₃CF = CFCu). Achieving both selective single and double CF₂ insertions into the same C-Cu bond is even more difficult. Herein, highly controllable single and double CF₂ insertions into CuCF₂H species with a TMSCF₂Br reagent have been described, affording two previously unknown fluoroalkylcopper species “Cu(CF₂)_nCF₂H” (n = 1 and 2) independently under different reaction conditions. This work represents the first example of both single and double CF₂ insertions into the same C-Cu bond in a highly selective manner. The synthetic value of the obtained “Cu(CF₂)_nCF₂H” (n = 1 and 2) species is demonstrated by their reactions with aryl iodides, halogenation agents, and cinnamyl chloride, which enables the direct transfer of HCF₂CF₂ and HCF₂CF₂CF₂ moieties into organic mols. The key to controllable fluorocarbon chain elongation from C₁ to C₂ and from C₁ to C₃ is presumably attributed to the different reactivities of “Cu(CF₂)_nCF₂H” species (n = 0, 1, 2 and 3) and the loading of the TMSCF₂Br reagent.

The title substitution reactions were achieved in the presence of a fluoride anion: the reaction of perfluoro-(5,6-dihydro-2H-1,4-oxazine) (I) with an equal amount of tri-Me(pentafluorophenyl) silane (II) provided not only a monosubstituted compound, i.e. perfluoro-(3-phenyl-5,6-dihydro-2H-1,4-oxazine), but also di- and trisubstituted compounds, i.e. perfluoro-(5,5-diphenyl-phenyl-5,6-dihydro-2H-1,4-oxazine) and perfluoro-(3,5,5-triphenyl-5,6-dihydro-2H-1,4-oxazine), while the reaction of I with three molar excess of II only gave trisubstituted compounds A significant heterocyclic ring effect was observed: the reaction of perfluoro-(3,4-dihydro-2H-pyrrole) (III) with II mainly gave a dimer of III, i.e. perfluoro-(5-pyrrolidino-3,4-dihydro-2H-pyrrole), with a trace amount of a monosubstituted compound, i.e. perfluoro-(5-phenyl-3,4-dihydro-2H-pyrrole).

The electronic structure of pentafluorophenyl-substituted silanes Ar_nSiMe_4-n (Ar = C₆H₅, C₆F₅, 4-FC₆H₄, 2,3,5,6-F₄C₅N; n = 1; Ar = C₆H₅, C₆F₅, n = 2, 4) was studied by x-ray emission and He(I) photoelectron spectroscopy. The He(I) photoelectron spectra were measured and interpreted from MNDO calculations, anal. of the p-fluoro effect, and relative intensities. Substitution of C₆F₅ for C₆H₅ in aryltrimethyl- and diaryldimethylsilanes results in enhanced ¦Ð interaction between the aryl and SiMe_n groups (n = 2, 3) by higher ¦Ð levels and has almost no effect on the charge on the Si atom.
