Organofluorine compounds are key materials applied in daily life because of their versatile utility as functional materials, pharmaceuticals, and agrochemicals. Development of the selective fluorination of organic molecules under safe conditions is therefore one of the most important subjects in modern synthetic organofluorine chemistry. Thus, various electrophilic fluorination reagents such as XeF₂, (PhSO₂)₂NF (NFSI), Et₂NSF₃ (DAST), (MeOCH

This article provides an outline of recent studies on selective electrochemical fluorination in ionic liquid fluoride salts toward green sustainable chemistry. First, a brief historical background of electrochemical fluorination in organic solvents is provided, and some particular problems and unique solvent effects associated with this technique are briefly mentioned. Second, recent progress in selective fluorination and fluorodesulfurization of organic molecules and macromolecules in ionic liq

On the double: When a poly(3-methylthiophene) (PT) film is doped on a bipolar electrode with Bu4NPF6 as supporting electrolyte, the film includes PF6− anions with a composition gradient along the potential gradient on the electrode. The use of Et4NCl results in partial chlorination of the PT film that reflects the potential gradient of the bipolar electrode (see picture; inset: photograph of the film). Detailed facts of importance to specialist readers are published as ”Supporting Information”.

Prins cyclization of homoallylic alcohols, thiols, and amines with various aldehydes in an ionic liquid HF salt (Et(4)NF.5HF) afforded the corresponding 4-fluorinated heterocycles in excellent yields.

Charged up: The selective electrochemical fluorination of organic compounds using the alkali-metal fluoride KF under very mild reaction conditions has been accomplished (see scheme). The long-standing problems of low solubility of metal fluorides in organic solvent and low nucleophilicity of fluoride ions for fluorination have been overcome by the use of of poly(ethylene glycol). Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer
