    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 invention relates to a method for producing o-chloromethyl benzoic acid chlorides of formula (I), in which R 1 to R 4 can be the same or different and represent hydrogen C 1 -C 4 alkyl, halogen or trifluoromethyl, by reaction benzo condensed lactones of formula (II), in which R 1 to R 4 have the above-mentioned meaning, with thionyl chloride. The inventive method is characterized in that the reaction is carried out in the presence of catalytic quantities of a Lewis acid and in the presence of catalytic quantities of a phosphine derivative.
