    Abstract: The process for preparing alkenyl-substituted bis(oxime ether) derivatives of the formula Iwhere:R1 is unsubstituted C1-C4-alkyl or C2-C4-alkenyl-, C2-C4-alkynyl- or phenyl-substituted methyl;R2, R4 independently of one another are hydrogen or methyl;R3, R5 independently of one another are hydrogen or C1-C4-alkyl, trifluoromethyl or phenyl andX is -C(=CHCH3)-COOCH3,-C(=CHOCH3)-COOCH3,-C(=NOCH3)-COOCH3,-C(=NOCH3)-CONHCH3 or-N(OCH3)-COOCH3,and intermediates which are obtainable by this process are described. Alkenyl-substituted bis(oxime ether) derivatives of the formula I are described in the literature as interesting crop protection agents.

    Abstract: The invention relates to a method for producing 1-substituted 5- and/or 3- hydroxypyrazoles of formulas (I) and (II), wherein R1 represents C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkinyl, C3-C6-cycloalkyl or C1 - C4-alkoxy, whereby these groups can be substituted by halogen, C1-C4-alkoxy, phenoxy, C1-C6-alkoxycarbonyl, C1-C6-alkylthiocarbony l or a cyclic ring system with 3-14 ring atoms, by reacting a 3-alkoxyacrylic acid alkyl ester of formula (III), wherein R2, R3 independently mean C1-C6-alkyl or C3-C6-cycloalky, with a hydrazine of formula (IV), wherein R1 has the above cited meaning, a) at a pH value of 6- 11 to form 5-hydroxypyrazoles of formula (I), or b) at a pH value of 11-14 to form 3-hydroxypyrazoles of formula (II).

    Abstract: Crystalline modification IV of pyraclostrobin (A) exhibits at least three reflexes in an X-ray powder diffractogram at 25[deg]C, where the reflections (d) are 6.02 +- 0.01 Å, 4.78 +- 0.01 Å, 4.01 +- 0.01 Å, 3.55 +- 0.01 Å and 3.01 +- 0.01 Å. Independent claims are included for: (1) the preparation of (A); (2) crystalline modification II of pyroclostobin (A1) exhibiting at least four reflexes in a X-ray powder diffractogram at 25[deg]C, where the reflections (d) are 5.93 +- 0.01 Å, 5.82 +- 0.01 Å, 4.89 +- 0.01 Å, 4.78 +- 0.01 Å, 4.71 +- 0.01 Å, 3.97 +- 0.01 Å, 3.89 +- 0.01 Å, 3.77 +- 0.01 Å, 3.75 +- 0.01 Å, 3.57 +- 0.01 Å and 3.43 +- 0.01 Å; (3) the preparation of (A1); and (4) a plant protection agent, which comprises pyraclostrobin in the form of modification IV or in the form of modification II and carrier materials and/or additives. ACTIVITY : Fungicide. MECHANISM OF ACTION : None given.
