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: 6239306
Abstract: Compounds of the formula (I) and their salts as defined in claim 1,
in which
R1 is CO—Q—R8, where R8=H or R
R2 and R3 are H or (C1-C4)alkyl,
R4 is H, R, RO, OH, RCO, RSO2, PhSO2
R5 is RSO2, PhSO2, PhCO, RNHSO2, R2NSO2, RCO, CHO, COCOR′, CW—T—R9, CW—NR10R11, CW—N(R12)2 or
R4 and R5 together are the chain (CH2)mB or —B1—(CH2)m1B— where B=SO2, m=3, 4; m1=2, 3;
T and W=O, S; Q=O, S, NR13 where R13=H, R;
R6=H, R, RO, RCO, ROCO, Hal, NO2, CN;
R7=H, CH3; R9=R; R10, R11=H, R; N(R12)2=heterocycle
A=pyrimidinyl and triazinyl radical or an analog thereof,
where R=(substituted) aliphatic hydrocarbon radical, are suitable as selective herbicides. They are prepared by analogous processes via sulfonamides, some of which are new, of the formula (II) (see claim 4).
