Process for the preparation of .beta.-fluoroalcohols of the formula (I) ##STR1## in which R.sup.1 and R.sup.2 represent straight-chain or branched alkyl and R.sup.3 and R.sup.4 represent hydrogen or alkyl, in which epoxides of the formula (II) ##STR2## are reacted with sodium hydrogen fluoride or potassium hydrogen fluoride under pressure in the presence of diluents.

prepared. Structure-activityrelationship (SAR) studies indicated that the in vitro antibacterial potency was the following order: 1-(1,1-dimethyl-2-fluoroethyl) greater than 1-[1-methyl-1-(fluoromethyl)-2-fluoroethyl] greater than 1-[1,1-(difluoromethyl)-2-fluoroethyl] substituents. In the quinolone series the monofluoro-tert-butyl derivatives were found to possess better in vitro antibacterial activity
