Preparation of 1-arylpyrazoles as insecticides and acaricides

Preparation of 1-arylpyrazoles as insecticides and acaricides. Jensen-Korte, Uta; Gehring, Reinhold; Schallner, Otto; Stettner, Joerg; Wroblowsky, Heinz Juergen; Becker, Benedikt; Stendel, Wilhelm; Homeyer, Bernhard; Behrenz, Wolfgang (Bayer A.-G. , Fed. Rep. Ger. 2712-93-8 and 106285-08-9 are cas registry numbers. These chemicals are also mentioned in this article.). Ger. Offen. DE 3529829 A1 26 Feb 1987, 27 pp. (Germany) CODEN: GWXXBX. CLASS: ICM: C07D231-22. ICS: C07D231-24; C07D401-04; A01N043-56. APPLICATION: DE 85-3529829 21 Aug 1985. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 The title compds. [I; R = (un)substituted Ph, pyridinyl; R1 = H, (halo)alkyl; R2 = (halo)alkyl, (un)substituted aryl, aralkyl; R3 = H, halo; n = 0-2] were prepd. as pesticides, esp. insecticides and acaricides. 2,6,4-Cl2(F3C)C6H2NHNH2 was cyclocondensed with CH2:CClCO2H to give 96% 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]pyrazole, which was condensed with Cl2FCSCl in HOAc to give 94% I [R = 2,6,4-Cl2(F3C)C6H2, R1 = NH2, R2 = Cl2FC, R3 = H, n = 0]. This was diazotized in AcOH/H3PO4 and deaminated with H3PO2 to give 36% I [R = 2,6,4-Cl2(F3C)C6H2, R1 = R3 = H, R2 = Cl2FC, n = 0] (II). II is a more effective insecticide and acaricide than several known pyrazoles. .

Fungicides for grain cultivation

Fungicides for grain cultivation. Kaspers, Helmut; Kuehle, Engelbert; Reinecke, Paul; Klauke, Erich (Bayer A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3211912 A1 13 Oct 1983, 14 pp. (German). (Germany).In this article, certain chemicals are used. Some of their cas registry numbers are 88709-14-2 and 2712-93-8 CODEN: GWXXBX. CLASS: IC: C07D209-76; C07D209-52; C07D209-48; A01N047-04. APPLICATION: DE 82-3211912 31 Mar 1982. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 5 Sulfenylated imides I [X = annulated isocyclic 6-membered arom. or hydroarom. Me (un)substituted ring, optionally (un)substituted CH2-bridged], useful as fungicides for grain cultivation, were prepd. Dropwise addn. of NEt3 to tetrahydrophthalimide and Cl2CFSCl in cyclohexane at 40-45° and stirring 1 h gave 92% II. Wheat treated with 0.01% II, then inoculated with Leptosphaeria nodorum, gave 42.5% infested plants; when the Cl3CS analog of II was used, 100% of the wheat became infected. .
