Perfluoro- (III), synthesised via direct fluorination of the sodio derivative of perfluoro- (I), readily converts diethyl sodio(phenyl)malonate and anisole to diethyl fluoro(phenyl)malonate and ortho- plus para-fluoroanisole respectively at ambient temperature; at 60 deg C it quickly converts benzene to fluorobenzene.The sodio-precursor (I) of the N-F compound (III) is easily made from pentafluoropyridine and trifluoromethanesulphonamide.
