Abstract

Photochemical Schiemann reactions of imidazole derivatives 1 and 4 were carried out in 1- butyl-3-methylimidazolium tetrafluoroborate ionic liquid [bmim][BF4] as solvent. The effects of temperature, co-solvent and wavelength on the rate of the reaction and product yield were examined. The use of ionic liquid increases the yield of the photochemical fluorodediazoniation reaction of 2 at 0° C. Careful temperature control is necessary to ...
