Patent number: 6265398
Abstract: The present invention relates to novel substituted pyridines/pyrimidines of the formula I
where
A is CH or N;
X is NH, O or S(O)q where q is 0, 1 or 2;
Y1, Y2 and Y3 independently of one another are a group of the formula —O—, —CO—, —CNR6—, —S(O)r— or —N(O)lR6— where l is 0 or 1 and where r is 0, 1 or 2, or a group of the formula CR7R8, or
Y1 or Y3 replace a direct bond;
Z is a direct bond, NR9, O, S(O)s where s is 0, 1 or 2, OSO2, SO2O, NR10SO2, SO2NR11, SiR12R13 or
where
U is a direct bond, NR14 or O;
W is oxygen or sulfur;
V is a direct bond, NR15 or oxygen;
m and n and 0, 1, 2, 3 or 4; where the radicals R1 to R15 have the meaning given in the description, to processes for their preparation, to their use as pesticides, fungicides and ovicides and to their use as veterinary medicaments.

Patent number: 6197729
Abstract: Compounds of formula I
where
R1 is hydrogen, chlorine, fluorine or methyl,
R2 and R3, which may be the same or different from each other, are hydrogen, halogen, cyano, (C1-C4)-alkyl, vinyl, ethynyl, (C1-C4)-alkoxy, (C1-C4)-alkoxy-(C1-C4)-alkyl, fluorovinyl or fluoroethyl, or
R2 and R3 together with the linking carbon atoms form a benzo ring, and
R4 is (C2-C4)-alkyl, (C2-C4)-alkenyl or (C3-C4)-alkinyl, each of which is substituted by at least two fluorine atoms and optionally substituted by C1-4-alkoxy, cyanomethoxy, (C3-C4)-alkenyloxy or (C3-C4)-alkinyloxy, are useful as pesticides, especially against insects, acarids and fungi. The invention includes a novel process for fluorinating certain pyrimidines.
