摘要： The invention concerns biphenylamides of general formula (I) and their salts (A = (A1), (A2) or (A3); wherein R?1 = F; R2¿ = H, halogen, alkyl, CF¿3?, alkoxy, alkylthio; R?3¿ = Cl, CF¿3; R?4 = H, CH¿3; R?5 = Cl, CH¿3?, CHF2, CF3; R?6 = CH¿3, CHF2, CF3). The invention also concerns agents containing (I), the preparation of (I) and these agents, and the use of both as fungicides.

摘要： A process is disclosed for producing isomer mixtures from O-phenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R1)-O-Ar and Ib: H¿2?N-O-CH(R?1)-CH¿2-O-Ar (wherein R1 represents alkyl, Ar where appropriate a substituted phenyl) and the corresponding salt mixtures. This process involves the following steps: (a) an isomer mixture of O-(2-hydroxyethyl)-oximes (IIa) and (IIb) (in which R2 is an alkyl and R3 is an alkyl or alkoxy, or R?2 and R3¿ together with the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO¿2-R?4 (wherein R4 represents an organic group and Hal is a halogen) in the presence of a base to form the corresponding sulphonate mixture of (IVa) and (IVb); (b) this sulphonate mixture is reacted in the presence of a base with a phenol of formula (V): HO-Ar to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) and (VIb); (c) the mixture is hydrolysed in the presence of an acid and, if required, (d) the O-phenoxyalkylhydroxyl amines (Ia) and (Ib) are released from the resulting salts using a mineral base. The O-phenoxyalkylhydroxyl amines (Ia/Ib) and their precursors (VIa/VIb) are important intermediate products for plant protective agents and drugs.

摘要： The disclosure is of 5-hydroxypyrazol-4-yl-carbonyl-substituted saccharin derivatives of formula (I), in which the substituents have the following meanings: L,M stand for hydrogen, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 alkylthio, chlorine, cyano, methylsulphonyl, nitro or trifluoromethyl; Z stands for hydrogen, C1-C4 alkyl, C3-C8 cycloalkyl, C3-C6-alkenyl, C3-C5-alkinyl, C1-C4 acyl, benzyl or phenyl (the phenyl rings optionally being each substituted by a halogen or C1-C4 alkyl); Q stands for a CO-J group; J stands for a 5-hydroxypyrazol ring linked at position 4 and of formula (II), in which R1 represents C¿1?-C4 alkyl, and R?2¿ represents hydrogen or methyl. Also disclosed are the salts of formula (I) compounds commonly used in agriculture.

摘要： Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R?1 and R2¿ are alkyl or R?1 and R2¿ and the common C atom are 5-membered to 7-membered cycloalkyl; R3 is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.
