  • Chemistry of organo halogenic molecules. 140, Role of the reagent structure on the transformations of hydroxy substituted organic molecules with the N-fluoro class of fluorinating reagents

    Hydroxa-substituted organic molecules were used as target molecule in investigations of the role of the reagent structure on the reactivity of three types of N-F class fluorinating reagents: ... 1-chlormethyl-4-fluoro-1,4-diazonoabicylo[2.2.2]octane bis(tetrafluoroborate) F-TEDA (1a), N-fluorobis(phenylsulfonyl)amine NSF (1b), and N-fluoropyridinium heptafluorodiborate-pyridine (1/1) NFP (1c). Methanol is stable, but hydroquinone is very quickly transformed in acetonitrile to quinone with F-TEDA at room temperature; on the other hand, NSF is less reactive, while oxidation with NFP is achived only at an elevated temperature; a structure variation of the hydroquinone derivatives did not influence oxidation. Fluorination was achived with monohydroxy-substituted aromatic compounds; a similar trend concerning the reactivity of N-F reagent (1) was also observed in a reaction with 4-methoxyphenol; although the thio analogue gave bis(4-methoxyphenyl) disulfide, the reactivity was changed and NSF was more reactive then F-TEDA and NFP.
