Caged Fluoride: Photochemistry and Applications of 4-Hydroxyphenacyl Fluoride
The quantitative, efficient (Φ = 0.8) photorelease of the fluoride ion upon UV-irradiation in aqueous media is introduced. The 4-hydroxyphenacyl chromophore is simultaneously transformed into UV-transparent 4-hydroxyphenylacetate via a photo-Favorskii rearrangement. The application of this process is demonstrated by photoinduced etching of mica and silicon by AFM.

Solvent directing immediate fluorination of aromatic ketones using 1- fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)
Reactions of aryl alkyl ketones with 1-fluoro-4-hydroxy1,4- diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Accufluor(TM) NFTh) in methanol result in selective and almost quantitative formation of the corresponding α-fluoroketones, while in acetonitrile exclusive fluorofunctionalisation of the activated aromatic ring take place.
