    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: N-Phenyltetrahydroindazoles of formula (I), where R1 is H or C1-4-alkyl; R2 is halogen, C1-4-alkyl or C1-4-haloalkyl; R3 is H or halogen; R4 is NO2, halogen, C1-4-alkyl or C1-4-haloalkyl; R5 is -XR6; X is -O-, -S-, -SO- or -SO2-; R6 is Alk-R7; Alk is a substituted or unsubstituted methylene, ethylene, propylene, butylene or pentamethylene chain, where one chain member can carry a spirolinked 2- to 5-membered C chain or where 2 ring members can be bridged via a C1-5-alkylene chain; R7 is CN, SCN, halogen or -YR11, where Y is -O-, -S-, -SO- or -SO2-; R10 is H, OH, C1-C4-alkyl, C1-C4-haloalkyl, C3-C5-cycloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, C3-C5-cycloalkoxy, C1-C4-alkylthio, C1-C4-haloalkylthio, -NH-R12, -N(C1-C4-alkyl)-R12, -N(C3-C4-alkenyl)-R12, -N(C3-C4-alkynyl)-R12, pyrrolidin-1-yl, piperid-1-yl, morpholin-4-yl, azepan-1-yl, (i) unsubstituted or substituted phenyl, benzyl, phenoxy or benzyloxy; R11 is C1-6-alkyl, C1-6-haloalkyl or C1-6-cycloalkyl; R12 is H, OH, C1-4-alkyl, C3-4-alkenyl, C3-4-alkynyl, C3-6-cycloalkyl, C1-4-alkoxy, C3-4-alkenyloxy, C3-4-alkenyloxy, C3-4-alkynyloxy, or substituted or unsubstituted phenyl or benzyl; and the agriculturally utilizable salts of formula (I), with the provisoes that the simultaneous meaning of R6 as dihalomethyl, R2 and R4 as chlorine and R3 as halogen is excluded; the simultaneous meaning of X as oxygen and R7 as OR11 or C1-C6-alkylthio is excluded; Alk must not carry a spiro-linked threemembered ring if R7 is halogen and R11 is not C1-6-alkyl if R1 is H, R2 is C14-haloalkyl, R3 is F, R4 is halogen and R7 is -OR11. Use: as herbicides; for desiccating/defoliating plants.

    Abstract: Oxazin(ethi)one compounds of the formula I: in which the variables Z, R 1 , R 2 , R 3 and n are as defined in claim 1 and A is a 5- or 6-membered carbocycle or a 5- or 6-membered heterocycle having 1, 2 or 3 heteroatoms selected from the group consisting of N, O and S, each of which cycles is attached via two carbon atoms to the oxazin(ethi)one ring, and the agriculturally useful salts of the oxazin(ethi)one compounds I are described. Moreover, the invention describes the use of compounds I and their salts for controlling phytopathogenic fungi, compositions which comprise the compounds I and/or their salts in a fungicidally effective amount and a method for controlling phytopathogenic fungi which comprises treating the fungi or the materials, plants, seeds or the soil threatened by fungal attack with a fungicidally effective amount of at least one compound of the formula I as claimed in claim 1 and/or a salt of I.
