新規フッ素化剤、IF5-ピリジン-HFの開発

抄録

Abstract: A novel fluorination reagent, IF₅-pyridine-HF. IF₅-pyridine-HF, was prepared from IF₅ and pyridine-HF, which is a pale yellow solid and air stable. When a sulfur compound was added to slurry of IF₅-pyridine-HF in CH₂Cl₂, the colour of the mixture changed to dark red and fluorination of the substrate took place. Oxidative fluorination of sulphide, desulfurizing-difluorination of benzyl sulphide, and desulfurizing-fluorination of thioacetal were successfully performed by IF₅-pyridine-HF, and 1-3 fluorine atoms were introduced to the substrate.
