In this paper, we report our efforts toward the development of a bromopentafluorosulfanylation reaction of terminal alkynes. The use of tetrabromomethane (CBr4) as a bromine atom source allowed the formation of the bromopentafluorosulfanylated product. Practically, however, the desired products could not be separated from the minor chloropentafluorosulfanylated products as well as the dibromoalkene side-products generated under those reaction conditions.

The ability of born nitride and carbon nanotubes to adsorb ClF3 was investigated by the density functional theory method. The electronic properties including HOMO and LUMO energies, density of states, chemical potential, electrophilicity index, softness, hardness, and natural bond orbital analysis were studied. Our findings indicate that among the studied tubes the (6,0) CNT is more suitable for adsorbing ClF3 molecule. The adsorption of ClF3 on the nanotubes significantly reduces the energy gap and hardness parameters of the tubes. This factor increases the conductivity of the system. The adsorption energies in the investigated models are negative, which confirm that the adsorption process is thermodynamically favorable and the complexes are stable. Also, among these compounds, (6,0) CNT- ClF3 has the greatest adsorption energy. QTAIM calculations confirm the observed adsorption energies.

Reaction of hexafluoro-1,4-naphthoquinone with various phenols was studied for the first time. It was shown that sodium acetate is a convenient reagent for implementation of the process. The investigated condensation led exclusively to substitution of two fluorine atoms in the quinone core. Based on performed research the method for preparation of substituted 2,3-diaryloxy-5,6,7,8-tetrafluoronaphthalene-1,4-diones was elaborated. Using similar conditions pentafluorobenzo[a]phenoxazine derivatives were obtained from 2-aminophenols. In contrast to phenols cyclic 1,3-diketones in the reaction with perfluoronaphthoquinone act as C-nucleophiles resulting in fluorinated polycondensed furans. Structures of key obtained products were proved using X-ray analysis.

Cyclooctane and cyclodecane are important medium-size rings in organic chemistry, and fluorination can significantly modulate the properties of organic molecules, such as polarity, viscosity, and acidity. In this quantum-chemical study, two CF2 groups replaced the methylene moieties of the most stable conformations of cyclooctane (boat-chair) and cyclodecane (boat-chair-boat) to evaluate the effect of head, corner, and edge substitution on the energetics of the possible structures, including both constitutional and stereochemical-type isomers. It was found that CF2 groups prefer to occupy head (at C5) and corner positions of the cyclooctane ring rather than head (at C1) and edge positions, as these latter positions orient the fluorines endo, causing transannular repulsion. However, the 2,7 isomer, which possesses an edge CF2 group, is remarkably stable due to an unprecedented transannular hydrogen bond between hydrogen at C3 and the CF2 at C7. Similar findings were obtained for the cyclodecane derivatives, indicating that fluorination is preferable in certain positions due to steric and strain relief, while the transannular hydrogen bond also plays a secondary role as a source of stabilization. Given the CF2 groups' ability to order the conformation of these medium-size rings, fluorination may be utilized in systems where this property is required, such as in liquid crystals.

PFAS, or per- and polyfluorinated alkyl substances, are among the most prevalent environmental contaminants. Because of their toxicity and widespread use, these substances must be regulated in order to reduce the associated hazards. Effective regulation requires accurate measurement of PFAS concentrations, but the lack of commercially available reference standards hinders the identification and quantification of novel PFAS discovered through nontarget analysis techniques. In this work, we aimed to fill this gap by synthetising new PFAS reference standards, based on findings reported in the literature through nontarget assays.
We performed the synthesis of 17 novel PFAS reference standards, including three fluorotelomer thioether amido sulfonic acid (FTSASs), three fluorotelomer sulfonyl amido sulfonic acid (FtSO2AoS), 6:2 Fluorotelomer sulfinyl amido sulfonic acid (6:2 FtSOAo), three perfluoroalkane sulfonamide diacetic acids (FASEE diacids), three perfluroalkyl amidoalkyl amine (PFAAAm), perfluoro (4-methyl-3,6-dioxaoct-7-ene) sodium sulfonate (PS acid sodium salt), perfluoro (4-methyl-3,6-dioxaoct-7-ene) sulfonic acid (PS acid), perfluoro-3-{ [1-(ethenyloxy)propan-2-yl]oxy}propanoic acid (EVE acid), and 6- (2,2,3,3,4,4,4-Heptafluorobutoxy)hexan-1-ol. Various chemical reactions were carried out to synthesise the chemicals, and the Dry Column Vacuum Chromatography (DCVC) was selected as the best purification technique. The linear isomer product was obtained by recrystallisation when branched isomers were present. The identity and purity of the synthesised reference standards were confirmed using a combination of NMR spectroscopy (¹H, ¹⁹F, ¹³C) and mass spectrometry (m/z, LC-MS, or GC–MS).

Recently, significant interest has been developed in pharmaceuticals containing fluorine The biological effects depend on the number and type of fluorine groups in the drug molecule. Much attention has been also paid to improve biological activity, in vivo stability, or bioavailability by studying the chemical modification of peptide structure. The most frequently studied fluorine-containing functional group is the trifluoromethyl group, which also occurs as a C(sp2)–CF3 bond. The trifluoromethyl alkyl group structure helps the peptide maintain its original β-turn structure, effectively mimicking the natural peptide bond, which allows it to function as its isostere. Therefore, the development of methods for synthesizing the trifluoromethylalkene group is becoming increasingly popular due to the potential of the products as building blocks of bioactive molecules. This review describes various methods for the preparation of the compounds with a trifluoromethylalkene group using trifluorinating reagents via the transition metal-mediated and the transition metal-free trifluoromethylation reactions.

In this paper, we report our initial results on the development of 2-(pentafluoro-λ6-sulfanyl)ethane-1-sulfonyl chloride as a novel pentafluorosulfanylation reagent. The targeted reagent was synthesized in five steps from vinyl acetate. As opposed to gaseous SF5Cl, 2-(pentafluoro-λ6-sulfanyl)ethane-1-sulfonyl chloride is a liquid under ambient conditions. Its reaction with substituted-phenylvinyl acetates under photoredox catalysis provided the corresponding α-SF5-ketones in low to moderate yields due in part to an incomplete desulfonylation step. Nonetheless, these results serve as a promising starting point for the further development of pentafluorosulfanylation reagent.

Solid-state chemistry of inorganic fluorides has gained great importance in the second half of 20th century. It aims at identifying the relationships between the structural networks and the physical properties resulting from interactions within these networks. One of the most significant results was the discovery in the 1960s of series of AxMF3 fluorides with structures similar to those of tungsten oxide bronzes. The investigation of other compounds mainly based on Al, Ga and transition metals with structures derived from ReO3, hexagonal tungsten bronze (HTB), tetragonal tungsten bronzes (TTB), defect pyrochlore and perovskite was soon launched in relation, in a first step, to their magnetic properties. Such interest was further extended to various properties such as positive electrodes in Li-ion batteries, UV absorbers, multiferroic components. Today, solid-state inorganic fluorides are present at the nano-sized level as components in many advanced technologies, including Li batteries or all solid-state fluorine batteries, micro- or nano-photonics, up- or down-conversion fluorescent probes, solid-state lasers, nonlinear optics, nuclear cycle, superhydrophobic coatings, etc. It has been pointed out that most of these outstanding properties can be correlated to the exceptional electronic properties of elemental fluorine, F2.
The aim of this article is to review the solid-state chemistry of fluorides having the formula AxMF3 over several decades, from their discovery in the 1960s to the interesting physical-chemical properties more recently investigated on these phases that derive from the ReO3, perovskite, defect-pyrochlore, hexagonal- and tetragonal- tungsten bronze types.
