Patent number: 6677002
Abstract: Novel phenylcyclohexanes of the formula I:
in which n is 0 to 7, Q1 and Q2 are H, or one of these radicals is alternatively CH3, r is 0, 1, 2, 3, 4 or 5, A is trans-1,4-cyclohexylene, 1,4-phenylene, 3-fluoro-1,4-phenylene or a single bond, X is F, Cl, —CF3, —CN, —OCF3 or —OCHF2, and Y and Z are each, independently of one another, H or F, with the proviso that, in the case where A is a single bond, Q1═Q2═H and simultaneously X═CN, Y and/or Z are F.

Patent number: 5942648
Abstract: Naphthalene derivatives of the fomula I ##STR1## in which: R.sup.1 is an alkyl or alkenyl radical which is unsubstituted, monosubstituted by CH or CF.sub.3 or monosubstituted by halogen and has 1 to 15 carbon atoms, it also being possible for one or more CH.sub.2 groups in these radicals to be replaced, in each case independently of one another, by --O--, --S--, ##STR2## --CO--, --CO--O--, --O--CO-- or --O--CO--O-- in such a manner that oxygen atoms are not linked directly to one another, ##STR3## m is 0, 1 or 2, n is 0 or 1, wherem+n is 1 or 2,Z.sup.1 and Z.sup.2 are each, independently of one another, --CH.sub.2 CH.sub.2 --, --C.tbd.C-- or a single bond,L.sup.1 and L.sup.2 independently of one another, are H or F,x is an alkyl or alkoxy radical which is unsubstituted, monosubstituted by CN or CF.sub.3 or substituted bi halogen and has 1 to 15 carbon atoms, or is OH, CN, SCN, OCN, NCS or Q--Y,whereQ is a single bond, (CF.sub.2).sub.r or O(CF.sub.2).sub.
