C6F5OH was unreactive toward Cl or Br in HOAc, aqueous HOAc, or H2O-Et2O at -10 to 0°. Anhydrous C6F5OK and Br in CCl4 yielded 44% 4-bromoperfluorocyclohexadienone (I, X = Br), which gave C6F5OH with Na2S2O3 or HBr; C6F5OK.2H2O gave I (X = Br, Cl) and their 2-haloisomers (II, X = Br, Cl) with Br in CCl4 and Cl in CH2Cl2, resp., with II predominating in both cases. 1-HOC10F7 yielded 87% 1-oxo-4-bromoperfluoro-1,4-dihydronaphthalene (III, X = Br) with Br in aqueous HOAc and a mixture of III (X = Cl) and its 2-chloro isomer (IV, X = Cl) with Cl in aqueous HOAc. 2-HOC10F7 and 2-KOC10F7 gave the resp. 2-oxo-1-haloperfluoro-1,4-dihydronaphthalenes (V) under identical conditions. 1-KOC10F7 and Br in CH2Cl2 gave III and IV (X = Br), with the latter predominating; IV (X = Br) was converted to III (X = Br) on standing.

KOH in 300 ml. tert-BuOH gave 12 g. 2,3,5,6-tetrafluoro-p-cresol, m. 52°. Reaction of 20 g. C₆F₅I with 2 g. KOH and 1 ml. H₂O in 100 ml. pyridine gave only one product, 2,3,5,6-tetrafluoro-4-iodophenol, m. 79-81°; benzoate m. 59-60.2°. Reaction of 66 g. C₆F₅Br with 28.5 g. KOH and 1 ml. H₂O in 150 ml. pyridine, however, gave a mixture of products: 3.5 g. 2-bromo-3,4,5,6-tetrafluorophenol, m. 41-3° (3,5-dinitrobenzoate, m. 104-5°); and 11.5 g. 4-bromo-2,3,5,6-tetrafluorophenol (3,5-dinitrobenzoate m. 131-3°). Similarly, 100 g. 2-chlorotetrafluoro-α,α,α-trifluorotoluene on treatment with 5.6 g. KOH and 1 ml. H₂O in 100 ml. pyridine gave 2.5 g. 2-chlorotrifluoro-α,α,α-trifluoro-o-cresol, b₁₅ 92-3°, n²⁴_D 1.4510; and 15 g. 2-chlorotrifluoro-α,α,α-trifluoro-p-cresol, b₁₅ 102-3°, n²⁴_D 1.4510.

HCONMe₂ was refluxed 14 hrs. to give 1.5 g. bis(perfluorophenyl) ether, m. 67-9°, and a second product, m. 145-8°, probably p-bis(pentafluorophenoxy)2,3,5,6-tetrafluorobenzene. Similarly, a solution of 0.6 g. Na in 50 ml. EtOH refluxed with 5.3 g. C₆F₅NMe₂ 2 hrs. gave 5.1 g. 4-ethoxy-2,3,5,6-tetrafluoro-N,N-dimethylaniline, b. 34°. Reactions with amines were next investigated. A mixture of 280 g. C₆F₆ and 400 ml. 28% aqueous NH₃ was rocked in a sealed bomb for 2 hrs. at 235° to give 236 g. C₆F₅NH₂, m. 34°, and 28 g. tetrafluorophenylenediamine (sublimed 75°/1 mm.) shown by its nuclear magnetic resonance spectrum to be essentially the meta isomer mixed with a small amount of the para isomer. Similarly, heating a mixture of 56 g. C₆F₆ and 110 ml. 30% aqueous MeNH₂ at 220° for 3 hrs. gave 59% C₆F₅NHMe, b. 170-2°, and 25% 2,3,5,6-tetrafluoro-N,N’-diphenylphenylenediamine, m. 94°. The reaction product obtained by heating 50 g. C₆F₆ and 110 ml. 25% aqueous Me₂NH at 235° for 1 hr. was distilled at 1 mm. pressure and five fractions were collected. The first fraction (65%), b₁ 88°, was C₆F₅NMe₂. Fraction 2, b₁ 88-126°, was shown by vapor phase chromatography to be C₆F₅NMe₂ with 3 other compounds Fraction 3, b₁ 126-134°, consisted of 3 isomers of bis(dimethylamino)tetrafluorobenzene with the meta-isomer predominating. Fraction 4, b₁ 134-40°, contained equal amounts of the meta and para isomers. Fraction 5, b₁ 140-8°, was pure para isomer. The meta and para isomers could be separated by vapor phase chromatography. Similarly, heating a mixture of 30 g. C₆F₅Br and 70 ml. 28% NH₄OH at 200° for 2 hrs. gave 22 g. p-bromotetrafluoroaniline, m. 61°. Heating 16 g. C₆F₅I and 30 ml. 8% NH₄OH at 165° for 2 hrs. gave 7.6 g. tetrafluoro-p-iodoaniline, m. 77°.

To 100 ml. anhydrous NH₃ at -70° were added 0.1 g. Fe(NO₃)₃ and 2.99 g. Na and, after disappearance of the blue color, 25 g. C₆F₅OMe during 45 min.

Diazotization of C₆F₅NH₂ required concentrated acids since the salts of the amine hydrolyzed very readily in dilute solutions In 48% HBr, diazotization of C₆F₅NH₂ gave C₆F₅N:NNHC₆F₅, probably owing to slow diazotization. The reaction was temperature-dependent, the diazoaminobenzene being formed much faster at 10° than at -10°. The product decomposed in warm HBr to give 5.4% C₆F₅Br and a mixture of o- and p-dibromotetrafluorobenzenes. In concentrated H₂SO₄ the reaction was very slow even at 25°. Addition of HOAc hastened it. Deamination with hypophosphorus acid gave a mixture probably of C₆F₅H and C₆H₂F₄. Better diazotization could be carried out in liquid HF and the diazo product underwent successful Sandmeyer reaction. A solution of 20 g. C₆F₅NH₂ in 75 ml. anhydrous HF at -20° was treated with 7.27 g. NaNO₂ during 30 min. After stirring for 1 hr. at -10° the mixture was treated with 17.6 g. KI during 30 min. and allowed to warm to 25° in 1 hr. to give 16.5 g. C₆F₅I, b₃₅ 77-9°. Use of 12 g. KBr and 15 g. Cu₂Br₂ instead of KI gave 35% C₆F₅Br. The reaction of diazotized amine with C₆F₅OLi gave C₆F₅N:N(O)C₆F₅, which decomposed on removal of solvent. The Sandmeyer nitrile synthesis was not successful. A solution of 10 g. C₆F₅NH₂ in 100 ml. HOAc was oxidized with 25 ml. 30% H₂O₂ at 25° for 24 hrs. to give decafluoroazoxybenzene (IV), m. 53-4°. A mixture of 5 g. IV, 15 g. Zn powder, 5 g. NH₄Cl, 10 ml. H₂O, and 75 ml. 95% EtOH refluxed 30 min. gave 2 g. decafluoroazobenzene, m. 57-9°. C₆F₆ reacted readily with organolithium compounds A solution of MeLi, prepared from 4.5 g. Li and 43 g. MeI in 50 ml. ether, was cooled to -10° to -20°, added dropwise to a solution of 60 g. C₆F₆ in 250 ml. pentane, and stirred for 17 hrs. at room temperature to give 34 g. C₆F₅Me, b. 115°. Similarly, reaction of BuLi, prepared from 1.86 g. Li and 18.3 g. BuBr in 30 ml. ether, with 25.3 g. C₆F₆ in 25 ml. ether gave 10.5 g. unreacted C₆F₆, 7 g. C₆F₅Bu, b₂₅ 86-7°, n²⁰_D 1.4229, and 2.5 g. of a compound, b₁ 230°, n²⁰_D 1.4683, probably impure tributyldifluorobenzene. Similarly, 32.7 g. C₆F₆ in 150 ml. ether with 0.18 mole PhLi in 250 ml. ether gave 8.5 g. 2,3,5,6-tetrafluoro-p-terphenyl, m. 220°, and 33 g. C₆F₅Ph, m. 69°. A similar reaction of 18.6 g. C₆F₆ and isopropenyllithium prepared from 12.1 g. 2-bromopropene gave 5 g. 2,3,4,5,6-pentafluoro-α-methylstyrene, b₅₂ 72-4°. With vinyllithium, prepared from 0.1 mole PhLi and 0.025 mole tetravinyltin, 18.6 g. C₆F₆ gave 4 g. unreacted C₆F₆ and 20% C₆F₅CH:CH₂, b₂₅ 34°. LiAlH₄ reduction of 21 g. C₆F₆ in ether gave 17 g. of a mixture of C₆F₆ and C₆F₅H which was separated by vapor phase chromatography to give 7.5 g. C₆HF₅. All the products in all above reactions were studied by infrared and nuclear magnetic resonance spectroscopy. The mechanism of reaction and the directional effects were discussed.

Yao, Zhaoyang published the artcilePyrene-Based Dopant-Free Hole-Transport Polymers with Fluorine-Induced Favorable Molecular Stacking Enable Efficient Perovskite Solar Cells, Category: bromides-buliding-blocks, the publication is Angewandte Chemie, International Edition (2022), 61(24), e202201847, database is CAplus and MEDLINE.

A new class of polymeric hole-transport materials (HTMs) are explored by inserting a two-dimensionally conjugated fluoro-substituted pyrene into thiophene and selenophene polymeric chains. The broad conjugated plane of pyrene and “Lewis soft” selenium atoms not only enhance the π-π stacking of HTM mols. greatly but also render a strong interaction with the perovskite surface, leading to an efficient charge transport/transfer in both the HTM layer and the perovskite/HTM interface. Note that fluorine substitution adjacent to pyrene boosts the stacking of HTMs towards a more favorable face-on orientation, further facilitating the efficient charge transport. As a result, perovskite solar cells (PSCs) employing PE10 as dopant-free HTM afford an excellent efficiency of 22.3 % and the dramatically enhanced device longevity, qualifying it among the best PSCs based on dopant-free HTMs.

A simple and sustainable one-step strategy for the preparation of electron-deficient aryl trifluoromethyl ethers (ArOCF₃) from the corresponding phenols by electrochem. synthesis is presented. Anodic oxidation of trifluoromethane sulfinate (Langlois reagent) leads to direct O-trifluoromethylation of phenol-derivatives bearing fluorine, chlorine, bromine and nitrile substituents under mild conditions in yields up to 75% and in gram-scale. This electrochem. protocol provides an economic and green synthesis for an otherwise inaccessible class of mols. without the need for expensive or toxic reagents, oxidants or metal catalysts.

Two perfluorinated triazines [2,4,6-tris(p-bromotetrafluorophenoxy)-1,3,5-triazine (2) and 2,4,6-tris(pentafluorophenoxy)-1,3,5-triazine (3)] were synthesized to study their crystal structure and inclusion character. Compound 3 forms channel inclusions with the solvents p-xylene and p-chlorotoluene, showing a stoichiometry of 2:1 (host:guest). The channels have dimensions of 7.6 × 3 Ų. The host-guest interactions, perfluorophenyl-Ph stacking, F···H- and CH···π(perfluorophenyl) contacts, were revealed by the crystallog. and solid state NMR spectroscopy studies. The reversibility of the sorption process through the gas phase could be demonstrated by X-ray diffraction. In contrast to the pentafluorinated compound 3, the tetrafluorinated one (2) showed no inclusions with a number of typical solvents.

Breen, Meghan E. published the artcileSubstrate Activity Screening with Kinases: Discovery of Small-Molecule Substrate-Competitive c-Src Inhibitors, HPLC of Formula: 1998-61-4, the publication is Angewandte Chemie, International Edition (2014), 53(27), 7010-7013, database is CAplus and MEDLINE.

Substrate-competitive kinase inhibitors represent a promising class of kinase inhibitors, however, there is no methodol. to selectively identify this type of inhibitor. Substrate activity screening was applied to tyrosine kinases. By using this methodol., the first small-mol. substrates for any protein kinase were discovered, as well as the first substrate-competitive inhibitors of c-Src with activity in both biochem. and cellular assays. Characterization of the lead inhibitor demonstrates that substrate-competitive kinase inhibitors possess unique properties, including cellular efficacy that matches biochem. potency and synergy with ATP-competitive inhibitors.

To further explore the nature of the photo-Favorskii rearrangement and its commitment to substrate photorelease from p-hydroxyphenacyl (pHP), an array of ten new fluorinated pHP γ-aminobutyric acid (GABA) derivatives was synthesized and photolyzed. The effects of fluorine substitution on the chromophore and the photophys. and photochem. properties of these new chromophores were shown to be derived primarily from the changes in the ground state pK_a of the phenolic groups. The quantum yields and rate constants for release are clustered around Φ_dis = 0.20 ± 0.05 and k_r = 8 ± 7 × 10⁷ s^-1 (H₂O), resp. The triplet lifetimes of the pHP GABA derivatives were concentrated in the range of 0.4-6.0 ns (H₂O). The corresponding deprotonated conjugate bases displayed reduced efficiencies by 50% or more (one exception) and exhibited a weak fluorescence in pH 8.2 buffer. Pump-probe spectroscopy studies have further defined the rates of intersystem crossing and the lifetimes of the reactive triplet state of the fluoro pHP chromophore.

Ding, Hairong published the artcileCompeting hydrogen bonding and halogen bonding interactions in crystal engineering: A case study of bi-functional donor molecules, Synthetic Route of 1998-61-4, the publication is Chemical Physics (2014), 30-37, database is CAplus.

Based on the recent determined co-crystals of a set of bi-functional donor mols. with two isomeric sym. acceptors, the competition between hydrogen bonding and halogen bonding interactions in crystal engineering was studied in this work using the M06-2x and ωB97XD methods. The preference of the occurrence of secondary weak interactions was observed in hydrogen-bonded complexes. Hydrogen bonding interactions are predicted to be much stronger than corresponding halogen bonding interactions. No obvious difference was found between the systems of the two acceptors under study. The model complexes, in which hydrogen bonds and halogen bonds coexist, show additivity. Finally, a comparison between theor. results and exptl. observations was presented, and the implications of the calculations on the supermol. assemblies based on the two interactions were also discussed.
