Japanese Patent JP2951400
Kind Code:
B2
Abstract:
1. Fluorobenzene derivatives of formula (I) in which R is H, an alkyl or alkenyl radical having 1 to 15 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, it also being possible for one or more CH2 groups in these radicals to be replaced, in each case independently of one another, by -O-, -S-, -CO-, -CO-O-, -O-CO- or -O-CO-O- in such a way that O atoms are not linked directly to one another, A<1> and A<2>, in each case independently of one another, are a (a) trans-1,4-cyclohexylene radical, in which, in addition, one or more non-adjacent CH2 groups may be replaced by -O- and/or -S-, (b) 1,4-phenylene radical, in which, in addition, one or two CH groups may be replaced by N, (c) radical from the group consisting of 1,4-cyclohexenylene, 1,4-bicyclo[2.2.2]octylene, piperidine-1,4-diyl, naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl and 1,2,3,4-tetrahydronaphthalene-2,6-diyl, where the radicals (a) and (b) may be substituted by CN or fluorine, Z<1> and Z<2> are each, independently of one another, -CO-O-, -O-CO-, -CH2O-, -OCH2-, -CH2CH2-, -CH=CH-, -C IDENTICAL C- or a single bond, and one of the radicals Z<1> and Z<2> is alternatively -(CH2)4- or -CH=CH-CH2CH2-, m is 0, 1 or 2, Y is F or Cl, and Q is -CF2-, -OCF2- or -OCHF-, with the proviso that, in the case where Q-Y = OCF3, (a) A<1> and A<2> are each, independently of one another, selected from the radicals (a) and (c), (b) one of the radicals Z<1> and Z<2> is -(CH2)4- or -CH=CH-CH2CH2-, and/or (c) .
