Abstract:
A cyclohexane compound of the formula I ##STR147## in which Y is alkyl or alkoxy having 1 to 10 carbon atoms which is unsubstituted or at least monosubstituted by halogen; alkenyl or alkenyloxy having 2 to 10 carbon atoms which is unsubstituted or at least monosubstituted by --CN, --CF.sub.3, or --F; or is --CN, --F, --OCHF.sub.2, --OCF.sub.3, --OCHFCF.sub.3 or --OCF.sub.2 CF.sub.3,X.sup.1, X.sup.2 and X.sup.3 are each independently of one another, H, F, Cl or CN in the axial position, where X.sup.1 and X.sup.3 are not simultaneously H,R.sup.1 is H, an alkyl or alkenyl radical having 1-12 carbon atoms which is unsubstituted, monosubstituted by CN or CF.sub.3 or at least monosubstituted by halogen, where one or more non-adjacent CH.sub.2 groups in these radicals, in each case independently of one another, are optionally replaced by --O--, --S--, --CO--, ##STR148## --CO--O--, --O--CO-- or --O--CO--O--, A.sup.1 and A.sup.2 are each independently of one another,a) a trans-1,4-cyclohexylene radical, in which, in addition, one or more non-adjacent CH.sub.2 groups are optionally replaced by --O-- and/or --S--,b) a 1,4-phenylene radical, in which, in addition, one or two CH groups are optionally replaced by N,c) a radical selected from the group consisting of 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, ord) a 1,4-cyclohexenylene radical,where the radicals a), b) and d) are optionally substituted by CN, Cl or F,Z.sup.1, Z.sup.2 and Z.sup.3 are each independently of one another, --OC--O--, --O--CO--, --CH.sub.2 O--, --O--, --O--CH.sub.2 --, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --C.tbd.C-- or a single bond,n and m, independently of one another, are 0, 1, 2 or 3andP is 0, 1, 2 or 3,wherem+n+p is 1, 2, 3 or 4.
