EQUILIBRIUM CH ACIDITY OF FLUORINE-CONTAINING FLUORENES IN 1,2-DIMETHOXYETHANE

It was established that the effect of the fluorine atoms on the equilibrium CH acidity of polyfluorinated 9-phenylfluorenes during successive substitution of the phenyl group by a pentafluorophenyl group and of the condensed benzene rings by tetrafluorinated rings in 9-phenylfluorene is nonadditive in character.On the basis of the UV and 1H and 19F NMR spectra of the carbanions of the polyfluorinated 9-phenylfluorenes and also of the pK value of 9-fluorofluorene it was proposed that the nonadditive character in the increase of the equilibrium acidity of polyfluorinated 9-phenylfluorenes is due to the preponderance of the stabilizing polar effect of the fluorine atoms over their destabilizing ?-donor effect.
