2,3,5,6-Tetrafluoro-[N-(3-aminopropyl)-ε-caprolactam]-4-pyridine
MolbankThe title compound was synthesized at a near-quantitative yield using the nucleophilic aromatic substitution of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) with perfluoropyridine (PFP). The purity and structure were determined by NMR (1H, 13C, 19F), GC-EIMS,

Determination of the fluorine solubility in various solvents
, 1993 Fluorine solubility is an important parameter in fluorination reactions, both from the viewpoint of controlling reaction exothermicity and of carrying out reactions homogeneously. Several solvents have been studied in order to define their solubilization

Electrochemical Properties of Nonflammable Organo-Fluorine Compounds for Lithium Ion Batteries
Electrochemical Properties of Nonflammable Organo-Fluorine Compounds for Lithium Ion BatteriesElectrochemical behavior of organo-fluorine compounds with high oxidation stability has been investigated. Oxidation currents of fluorine compound-containing EC/DEC solutions were much smaller than those of EC/DEC and EC/DEC/PC at the higher potentials than 6 V vs Li/Li+. Electrochemical reduction of fluorine compounds started at ca.
