The invention relates to fluorocyclohexane derivatives of the formula I in which R1, Z1, Z2, L1, L2, L3 and X are as defined as below: X is alkyl or alkoxy having 1 to 10 carbon atoms which is unsubstituted or substituted by halogen, alkenyl or alkenyloxy having 2 to 10 carbon atoms which is unsubstituted or substituted by -CN, -CF3 or -F, or is -CN, -F, -OCHF2, -OCF3, -OCHFCF3 or -OCF2CF3, L1, L2 and L3 are each, independently of one another, H or F, R1 is H, an alkyl or alkenyl radical having 1-12 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or substituted by halogen, where one or more non-adjacent CH2 groups in these radicals may also, in each case independently of one another, be replaced by -O-, -S-, -CO-, -+566 -, -CO-O-, -O-CO- or -O-CO-O-, Z1 and Z2 are each, independently of one another, -CO-O-, -O-CO-, -CH2O-, -O-, -O-CH2-, -CH2CH2-, -CH=CH-, -C 3BOND C- or a single bond, with the proviso that compounds of the formula I in which L1 is H and Z2 is simultaneously a single bond are excluded. |
