    Abstract: The invention concerns a process for preparing nitrobiphenylene of formula (I) wherein m stands for 1 or 2, R means halogen, R' or OR', R' being a C-organic group which can carry groups which are inert in the reaction conditions, n stands for 0, 1, 2 or 3 and, if n is 2 or 3, the R groups can also be different. According to the invention, a chloronitrobenzene of formula (II) is reacted in the presence of a palladium catalyst and a base in a solvent with a phenyl boric acid (IIIa), one of its alkyl esters of formula (IIIb), R meaning C1-C6 alkyl, or one of its anhydrides. The compounds (I) are suitable as initial products for biphenylamines which are in turn intermediate products for fungicidal plant-growth substances.

    Abstract: The invention relates to a novel method of producing the compounds of formul a (I) wherein the substituents have the following meanings: n is 0,1 or 2; R1, R2 represent C1-C6-alkyl; R3, R4, R5 are hydrogen, C1-C6-alkyl or R4 and R5 together form a bond; R6 is C1, Br. Said method comprises the following step s: a synthesis sequence starting from 1,2-dialkylbenzenes of formula (II); halogenation to form 3,6-dihalogen-1,2-dialkylbenzenes; haloalkylation to fo rm benzyl bromides; oxidation to form benzaldehydes; reaction with alkenes to form isoxazoles; reaction to form thioethers and optionally oxidation to for m sulfenyl or sulfonyl derivatives of formula (I).

    Abstract: Preparation of 4-(4-alkylsulfonyl-3-isoxazolyl- benzoyl)-5-hydroxypyrazole derivatives (I) involves reacting a hydroxypyrazole (II) with a bromobenzene (III) in presence of carbon monoxide, a palladium catalyst, a potassium salt and an amine. Preparation of benzoylpyrazole derivatives of formula (I) comprises reacting a hydroxypyrazole compound of formula (II) with a bromobenzene of formula (III) in the presence of carbon monoxide, a palladium catalyst, one or more equivalents of a potassium salt and one or more equivalents of a tertiary amine of formula N(Ra)3 (IV). Reaction is at 0-40 kg/cm and 100-140 deg C. R , R = 1-4C alkyl; R = Cl or CH3; R = H or 1-4C alkyl; M = H or alkali metal; Ra = 1-6C alkyl, or one can be phenyl or naphthyl; the isoxazole or isoxazoline residue is bonded in the 3- or 5-position.
