4-X-4'-fluorobenzophenones undergo the expected nucleophilic substitution reactions with the alkali metal salts of 4-Y-4'-hydroxydiphenyl ethers at 140 deg C in diphenyl sulphone as solvent: the Hammett ρ value is 1.02 for the X substituents and -0.34 for the Y substituents.The order of reactivity of the alkali metal salts is Cs > K > Na.The related reaction of fluorobenzophenone with potassium 4-Z-phenolates under the same conditions gives a ρ value of -2.28.This result has been used to calculate the corresponding rate coefficients for the reaction of the mono- and di-potassium salts of hydroquinone with fluorobenzophenone.
