Description
  • Several phenylazonaphthols were prepared in 1-butyl-3-methylimidazolium tetrafluoroborate (an ionic liquid) using a coupling reaction of (4-X-benzene)diazonium tetrafluoroborates (X = H and NO2) with 1- and 2-naphthols and their sodium salts. H-1 NMR spectra of the reaction products were measured and results compared with previously published data. The reaction of benzenediazonium tetrafluoroborates with sodium salts of 1- and 2-naphthols in 1-butyl-3-methyl-imidazolium tetrafluoroborate was faster compared with that when I - and 2-naphthols were used. 4-Nitrobenzenediazonium tetrafluoroborate was much more reactive than benzenediazonium tetrafluoroborate.

  • Několik fenylazonaftolů bylo připraveno v 1-butyl-3-methylimidazolium tetrafluoroborátu (iontová kapalina) kopulací (4-X-benzen)diazonium tetrafluoroborátů (X = H a NO2) s 1- a 2-naftolem a jejich sodnými solemi. H-1 NMR spektra reakčních produktů byla srovnána s publikovanými daty. Reakce benzenediazonium tetrafluoroboratů se sodnými solemi 1- a 2-naftolu v 1-butyl-3-methyl-imidazolium tetrafluoroborátu byla rychlejší ve srovnání se samotným 1 - a 2-naftolem. 4-Nitrobenzendiazonium tetrafluoroborát byl mnohem reaktivnější než benzendiazonium tetrafluoroborát.
