    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.

    Abstract: The present invention relates to a process for the preparation of 1,2,4-triazol-1-ylmethyloxiranes of the formula I in which A and B are identical or different and, independently of one another, are C 1 -C 4 -alkyl, phenyl-C 1 -C 2 -alkyl, C 3 -C 6 -cycloalkyl, C 3 -C 6 -cycloalkenyl, tetrahydropyranyl, tetrahydrofuranyl, dioxanyl or phenyl, where the phenyl radical can carry one to three substituents chosen from the group: halogen, nitro, C 1 -C 4 -alkyl, C l -C 4 -alkyloxy, phenoxy, amino, C 1 -C 2 -haloalkyl or phenylsulfonyl, which comprises reacting a) an oxirane of the formula II in which A and B have the meanings given above and L is a nucleophilically substitutable leaving group, with 4-amino-1,2,4-triazole of the formula III to give 4-amino-1,2,4-triazolium salts of the formula IV and b) deaminating the 4-amino-1,2,4-triazolium salts IV with alkali metal nitrites and acid or organic nitrites to give 1,2,4-triazol-1-ylmethyloxiranes of the formula I, and to 4-aminotriazolium salts of the formula IV as intermediates.

    Abstract: The invention relates to a method for producing 2,3-cis-substituted 2-aryl propenals by condensing a 2-aryl acetaldehyde I with a non-enolizable aldehyde compound II in the presence of a base. The inventive method is characterized in that the reaction is carried out in a solvent mixture comprising at least one water-miscible organic solvent and water at a volume ratio V solvent :V water ranging between 10:1 and 0.5:1.
