Organo-fluorine compounds are the substances of considerable interest in various industrial fields due to their unique physical and chemical properties. Despite increased demand in wide fields of science, synthesis of fluoro-organic compounds is still often faced with problems such as the difficulties in handling of fluorinating reagents and in controlling of chemical reactions. Recently, flow ...

We modelled the adsorption of benzene, fluorobenzene and meta-di-fluorobenzene on Cu(110) by Density Functional Theory. We found that the adsorption configuration depends on the coverage. At high coverage, benzene assumes a tilted position, while at low coverage a horizontal slightly distorted geometry is favoured. Functionalizing the benzene ring with one or two fluorine atoms weakens the bond...

The synthesis of 4-[18F]fluoroguaiacol (4-[18F]fluoro-2-methoxyphenol) has been achieved in no-carrier-added form starting from 2-methoxy-4-nitrobenzaldehyde, using nucleophilic aromatic substitution by [18F]fluoride followed by Baeyer-Villiger oxidation of the benzaldehyde to the phenol. Demethylation with boron tribromide gave 4-[18F]fluorocatechol (1,2-dihydroxy-4-[18F]fluorobenzene) with an...

The main effect of the introduction of fluorine to diamond-like carbon (FDLC) thin films is the reduction in surface free energy (SFE). Regarding tribological properties, frequent allusions to low friction are found in the literature. However, studies proving a direct relationship between fluorine content in DLC films and macroscopic friction reduction are hard to find, while others state fluor...

We review here some of our recent work on the synthesis and characterisation of new perovskite-related oxide fluorides. We demonstrate the use of low temperature fluorination methods for the preparation of new phases with high fluorine contents. We also show how fluorine can be accommodated in different sites according to the structural details of the initial oxide and the fluorine content. Imp...

Due to the unpredictable nature of organic fluorine in its participation in the formation of different supramolecular motifs which concomitantly influences the physicochemical properties of the compounds of interest, the study of noncovalent interactions involving organic fluorine will always be an expanding area of research amongst the scientific community. The participation of organic fluorin...

OBJECTIVE: To elucidate the participation of the independent and combined long term effect of various concentrations of iodine and fluorine on the pathogenesis of goiter and fluorosis in mice. METHODS: Nine drinking water supplies with different iodine and fluorine content were prepared by combination of potassium iodate and sodium fluoride solutions in bidistilled water. The concentrations of ...

Organofluorines represent a rapidly expanding proportion of molecules that are used in pharmaceuticals, diagnostics, agrochemicals, and materials. Despite the prevalence of fluorine in synthetic compounds, the known biological scope is limited to a single pathway that produces fluoroacetate. Here, we demonstrate that this pathway can be exploited as a source of fluorinated building blocks for i...
