## Abstract

New 2-oximino-2-phenyl-acetamides of the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 m and n have the meanings given in the description, pesticides.

## Background
The invention relates to new 2-oximino-2-phenyl-acetamides, to a process for their preparation and to their use as pesticides.

It has been disclosed that certain 2-methoximino-2-phenyl-acetates have fungicidal properties (cf. EP-OS (European Published Specification) 0,400,417). For example, methyl 2-methoximino-2-[2-(2-methylphenoxymethyl)-phenyl]-acetate can be used for combating fungi. However, the activity of this substance is not entirely satisfactory in all fields of application, in particular where the application rates are low.

New 2-oximino-2-phenyl-acetamides of the formula ##STR2## in which

R.sup.1 and R.sup.2 independently of one another in each case represent hydrogen, alkyl or alkoxy,

R.sup.3 represents hydrogen, alkyl or alkoxy,

R.sup.4 and R.sup.5 independently of one another in each case represent halogen, cyano, nitro, formyl, carbamoyl, thiocarbamoyl, alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkenyl, alkenyloxy, halogenoalkyl, halogenoalkoxy, halogenoalkylthio, halogenoalkylsul-phinyl, halogenoalkylsulphonyl, halogenoalkenyl, halogenoalkenyloxy, N-alkylamino, dialkylamino, alkylcarbonyl, alkylcarbonyloxy, alkoxycarbonyl, alkylsulphonyloxy, hydroximinoalkyl, alkoximinoalkyl or represent in each case optionally substituted cycloalkyl, heterocyclyl, phenyl, phenoxy, benzyl, benzyloxy, phenylethyl or phenylethyloxy,

m represents the numbers 0, 1, 2, 3 or 4,

n represents the numbers 0, 1, 2, 3 or 4,

A represents a group of the formula --CH.sub.2 --O--; --O--CH.sub.2 --; --CH.sub.2 --S-- or --S--CH.sub.2 --,

R.sup.6 represents either hydrogen, halogen, cyano, nitro, formyl, carbamoyl, thiocarbamoyl, alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkenyl, alkenyloxy, halogenoalkyl, halogenoalkoxy, halogenoalkylthio, halogenoalkylsulphinyl, halogenoalkylsulphonyl, halogenoalkenyl, halogenoalkenyloxy, N-alkylamino, dialkylsunino, alkylcarbonyl, alkylcarbonyloxy, alkoxycarbonyl, alkylsulphonyloxy, hydroximinoalkyl, alkoximinoalkyl, or represents in each case optionally substituted cycloalkyl, heterocyclyl, phenyl, phenoxy, benzyl, benzyloxy, phenylethyl or phenylethyloxy and

R.sup.7 represents halogenoalkoxy or halogenoalkylthio, or

R.sup.6 and R.sup.7 together represent an optionally substituted, bivalent alkanediyl radical which contains one or more oxygen or sulphur atoms, have now been found.

If appropriate, the compounds of the formula (I) can exist as geometric and/or optical isomers or variously composed isomer mixtures, depending on the nature of the substituents. The invention relates both to the pure isomers and to the isomer mixtures.

Furthermore, it has been found that 2-oximino-2-phenylacetamides of the formula (I) are obtained when 2-oximino-2-phenyl-acetates of the formula ##STR3## in which

R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, A, m and n have the above-mentioned meanings and

R represents alkyl, are reacted with ammonia or amines of the formula ##STR4## in which

R.sup.1 and R.sup.2 have the abovementioned meanings, if appropriate in the presence of a diluent and if appropriate in the presence of an acid-binding agent.

Finally, it has been found that the new 2-oximino-2-phenyl-acetamides of the formula (I) are highly suitable for use in pest control.

Surprisingly, the 2-oximino-2-phenyl-acetamides of the formula (I) according to the invention show a considerably better activity against phytopathogenic microorganisms than methyl 2-methoximino-2-[2-(2-methyl-phenoxymethyl)-phenyl]-acetate, which is a previously known active substance having a similar constitution and the same direction of action.
