Abstract:
A pyrimidine derivative expressed by the general formula (1) ##STR68##wherein R represents hydrogen atom or an alkyl group having 1 to 20 carbon atoms, at least one hydrogen atom in the alkyl group may be replaced by a halogen atom, and at least one --CH.sub.2 -- in the alkyl group may be replaced by oxygen atom or --CH.dbd.CH-- but in no case oxygen atoms adjoin to each other;n1 and n2 are independently 0, 1, or 2 provided that the sum of n1 and n2 is 1 or 2,ring A and ring B independently represent 1,4-phenylene, fluorine substituted 1,4-phenylene expressed by the formula (a) ##STR69##or 1,4-cyclohexylene provided that at least one of ring A and ring B is fluorine substituted 1,4-phenylene expressed by the formula (a), and that when ring A and/or ring B is the fluorine substituted 1,4-phenylene, then n1 and/or n2 is 1 or 2, at least one not-adjacent --CH.sub.2 -- in the 1,4-cyclohexylene may be replaced by oxygen atom, and at least one hydrogen atom in the 1,4-cyclohexylene may be replaced by a halogen atom;Za, Zb, and Zc independently represent single bond, --CH.sub.2 CH.sub.2 --, --COO--, --CF.sub.2 --, or --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 --;Q.sub.1, Q.sub.2, Q.sub.3 Q.sub.4 Q.sub.5, Q.sub.6, and Q.sub.7 independently represent hydrogen atom, a halogen atom, or methyl group provided that when at least one of Za, Zb, and Zc is --CH.sub.2 CH.sub.2 --, then Q.sub.2 is fluorine atom, that when any one of Za, Zb, and Zc is --COO--, then Q.sub.1, Q.sub.2, Q.sub.3, Q.sub.4, Q.sub.5, Q.sub.6, and Q.sub.7 independently represent hydrogen atom, fluorine atom, or methyl group, and that when Za, Zb, and Zc are all single bonds, then Q.sub.1, Q.sub.2, Q.sub.3, Q.sub.4, Q.sub.5, Q.sub.6, and Q.sub.7 independently represent hydrogen atom or fluorine atom;Y represents a halogen atom, or a halogenated straight chain alkyl group having 1 to 5 carbon atoms, at least one not-adjacent methylene group in the halogenated alkyl group may be replaced by oxygen atom or sulfur atom, provided that when the halogenated alkyl group has two carbon atoms, then in no case are all hydrogen atoms in the halogenated alkyl group replaced by fluorine atoms, and that when the halogenated alkyl group has 3 to 5 carbon atoms, then a not-adjacent methylene group is replaced by oxygen atom or sulfur atom; andeach atom constituting this compound may be replaced by its isotope.
