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
