Rh-Catalyzed Highly Enantioselective Synthesis of Aliphatic Sulfonyl Fluorides

open access: yesiScience, 2019
Summary: Rh-catalyzed, highly enantioselective (up to 99.8% ee) synthesis of aliphatic sulfonyl fluorides was accomplished. This protocol provides a portal to a class of novel 2-aryl substituted chiral sulfonyl fluorides, which are otherwise extremely ...

Deoxyfluorination of acyl fluorides to trifluoromethyl compounds by FLUOLEAD®/Olah’s reagent under solvent-free conditions

open access: yesBeilstein Journal of Organic Chemistry, 2020
A new protocol enabling the formation of trifluoromethyl compounds from acyl fluorides has been developed. The combination of FLUOLEAD® and Olah’s reagent in solvent-free conditions at 70 °C initiated the significant deoxyfluorination of the acyl ...

Termite resistance of pine wood treated with nano metal fluorides [PDF]

open access: yes, 2020
Fluorides are well-known as wood preservatives. One of the limitations of fluoride-based wood preservatives is their high leachability. Alternative to current fluoride salts such as NaF used in wood protection are low water-soluble fluorides.

Luminescent properties of Bax Mg(2−x)F4:W ceramics

open access: yesEurasian Journal of Physics and Functional Materials, 2023
Ceramics based on alkaline earth metal fluorides activated by tungsten has been obtained by radiation synthesis. The synthesis was realized by direct action on the mixture with an activator of a powerful flow of high-energy electrons without the use of ...

Buffering Capacity and Effects of Sodium Hexametaphosphate Nanoparticles and Fluoride on the Inorganic Components of Cariogenic-Related Biofilms In Vitro

open access: yesAntibiotics, 2022
Despite the remarkable effects of sodium hexametaphosphate nanoparticles (HMPnano) on dental enamel de-/re-mineralization processes, information on the effects of these nanoparticles on biofilms is scarce. This study assessed the effects of HMPnano, with

Prediction for new magnetoelectric fluorides [PDF]

open access: yes, 2007
We use symmetry considerations in order to predict new magnetoelectric fluorides. In addition to these magnetoelectric properties, we discuss which among these fluorides are the ones susceptible to present multiferroic properties.

Content of Fluorine in Drinking Water in FYR Macedonia

open access: yesBalkan Journal of Dental Medicine, 2014
From all the methods applied in preventing dental caries, the most significant is the use of fluorides. Nowadays, 6 decades after its massive use, it can certainly be argued that it is the most efficient, cheapest and safest way of preventing dental ...

Determination of fluoride content in drinking water and tea infusions using fluoride ion selective electrode [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2007
Potentiometric analysis of fluoride content (as F- ion) in solutions by using fluoride ion-selective electrode is simple, reliable and cheap. Very small concentrations of fluoride-ions (to 10-6 mol/dm3) can be determined by fluoride selective electrode ...
