- METHOD FOR PRODUCING PYRIMIDINE COMPOUND
-
To provide a method for producing pyrimidine compound useful as an intermediate for agricultural chemicals or pharmaceuticals, which is simple in operation, presents high yield and produces only a small amount of by-products. The method comprises reacting a compound represented by the formula (I) with a compound represented by the formula (II) in the presence of a pyridine compound to produce a compound represented by the formula (III), a compound represented by the formula (IV) or their mixture.

- Method for producing a solid herbicide formulation
-
The invention relates to a method for producing a solid herbicide formulation containing a) a herbicide from the group of sulfonylurea, or the salts thereof which are useful in the agricultural domain, b) optionally at least one other herbicide, c) optionally a safener, and d) at least one formulation adjuvant. A suspension is formed in water, consisting of the sulfonylurea a), optionally at least one other herbicide b), optionally a safener c) and at least one formulation adjuvant d). The suspension is adjusted to a pH value between 6.5 and 8 by adding an acid or a base, and is then dried to obtain the solid formulation.

- N-phenylpyrrolidines
-
The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives of the formula I below are suitable for protecting crop plants against the phytotoxic action of herbicides and for regulating the plant growth. The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives are those of the formula I STR1 wherein A is --COOR1, --COSR1, --COO? M≈, --CONR2 R3 or --COCl; R1 is hydrogen, C1 -C4 alkyl, C2 -C6 alkenyl or C2 -C6 alkynyl; R2 and R3 independently of one another are hydrogen, C1 -C4 alkyl or C3 -C7 cycloalkyl; or R2 and R3 together with the nitrogen atom to which they are bonded are a saturated 3- to 7-membered heterocycle which can contain an additional hetero atom selected from the group comprising O, N and S and which is unsubstituted or up to trisubstituted by C1 14 C4 alkyl; and M≈ is the equivalent of an alkali metal cation or an alkaline earth metal cation or HN≈ (R2)3, and their isomers in optically pure or enriched form.
