| abstract |
The invention relates to novel benzene derivatives of the formula I ##STR1## in which n is 0, 1, 2, 3, 4, 5, 6 or 7, n Q is --O--, --CH═CH-- or a single bond, n r is 0, 1, 2, 3, 4 or 5, n s is 0, 1 or 2, n X is F, Cl, OCHF 2 or CF 3 , n L is H or F, and n A is ##STR2## Z, Z-Ar, Ar-Z, Z-Cyc in which Z is a single bond, --(CH 2 ) 2 -- or --(CH 2 ) 4 --, Ar is 1,4-phenylene or biphenyl-4,4'-diyl and Cyc is trans-1,4-cyclohexylene. |
