Patent number: 6589949
Abstract: The invention relates to novel 3-oxo-2,1-benzisomazol-1(3H)-carboxamides (I), where R1, R2 are the same or different and independently=H, halogen, C1 C6 alkyl C1 C6 alkoxy, C1 C3 perfluoroalkyl, or a group NR5R6; R3, R4 are the same or different and independently=C1 C8 alkyl, whose carbon chain is optionally interrupted by an O, S or NR7 and is optionally singly or severally substituted by C3 C6 cycloalkyl, C1 C4 alkoxy, OH, halogen or NR8R9; C3 C8 cycloalkyl whose carbon chain is optionally interrupted by an O, S or NR10 and is optionally singly or severally substituted by C1 C4 alkoxy, OH, halogen or NR11R12, or R3 and R4 together with a nitrogen atom form a saturated or partially unsaturated 3- to 10-membered mono- or bi-cyclic heteocycle, which, optionally, contains up to two further heteroatoms, from N, O or S and is, optionally, substituted by C1 C4 alkyl, C1 C4 alkoxy, OH, halogen, COOR13 or NR14R15 and X=O or S.

Patent number: 6566307
Abstract: Pyrazoles of the formula I
where:
R1 is hydrogen, nitro, halogen, cyano, thiocyanato or an aliphatic radical;
R2 is a substituted sulfur, nitrogen or phosphorus atom;
R3 is hydrogen, halogen or an aliphatic radical;
R4, R5 are hydrogen, nitro, halogen, cyano, thiocyanato, or an aliphatic radical;
R6 is hydrogen, halogen, C1-C6-alkyl, C1-C6-alkoxy, C3-C8-cycloalkyl;
R7, R8, R9 are hydrogen, C1-C6-alkyl, but at most one of the radicals R7, R8 and R9 is hydrogen;
and their tautomers and agriculturally useful salts are described.
Moreover, the invention relates to processes for preparing compounds of the formula I, to compositions comprising them and to the use of the compounds of the formula I and of the compositions comprising them for controlling harmful plants.
