α-Fluorination of carbonyls with nucleophilic fluorine
Nature Chemistry, 2019Given the unique properties of fluorine, and the ability of fluorination to change the properties of organic molecules, there is significant interest from medicinal chemists in innovative methodologies that enable the synthesis of new fluorinated motifs.

Fluorinations Not Using Fluorine Gas
2022The introduction of fluorine in pharmaceuticals and agrochemicals can be highly advantageous. The substitution of one or just a few hydrogen atoms by fluorine can dramatically alter a compounds acidity/basicity and lipophilicity, which may result in an improvement of its biological and/or pharmaceutical properties.

Investigation of fluorination by atomic fluorine
Journal of Fluorine Chemistry, 1991Abstract The process of fluorination of uranium tetrafluoride by atomic fluorine has been investigated on a closed circulation facility. The concentration of atomic fluorine in the flux was estimated using thermocouples. The ratio of fluorination at different distances from the atomic fluorine source was determined.

Journal of Drug Targeting, 1994
Stable fluorinated vesicles--i.e. vesicles with a hydrophobic and lipophobic fluorinated film within their bilayer membranes--have been obtained from a variety of neutral, zwitterionic or anionic fluorinated amphiphiles, including single chain phosphocholine derivatives, double-chain phospholipids, glycolipids and glycophospholipids, as well as from ...

Current Pharmaceutical Design, 1970
Abstract: Following the discovery of nalidixic acid in 1962, numerous structural modifications have been made to the quinolone nucleus to increase antimicrobial activit> and improve pharmacokinetic performance. A major advance occured during the 1980\ with the discovery that a fluorine at position-6 conferred broad and potent antimicrobial activity,

Chemistry - A European Journal, 2001
Recent developments in fluorination of fullerenes coupled with HPLC separation have permitted the isolation and subsequent structural characterisation of many derivatives, a number of which have novel and unexpected structures. The good solubility of fluorofullerenes, high reactivity towards nucleophiles and enhanced dienophilicity of the unsubstituted

Fluorinated nanocarbons using fluorinating agent: Strategies of fluorination and applications
The European Physical Journal B, 2009The fluorination method strongly influences the physical properties of the resulting fluorinated carbon materials. Two fluorination ways, direct fluorination under pure fluorine gas and controlled fluorination by the decomposition of TbF4, have been used for the fluorination of particular nanocarbons: carbon nanofibers and a mixture of carbon nanodiscs
