2-cyano-2-alkoximino-acetamides

A 2-cyano-2-alkoximino-acetamide of the formula ##STR330## in which R.sup.1 represents oxazolyl, isoxazolyl, or oxazolylalkyl or isoxazolylalkyl having 1 to 6 carbon atoms in the alkyl part, each of the foregoing of which is optionally monosubstituted or polysubstituted and/or benzene-fused, the substituents being identical or different and substituents of the oxazolyl or isoxazolyl parts and/or of the benzene-fused rings in each case being hydroxyl, halogen, cyano, in each case straight-chain or branched alkyl, alkenyl, alkoxy or alkylthio in each case having up to 4 carbon atoms, aralkyl having 6 to 10 carbon atoms in the aryl part and 1 to 3 carbon atoms in the straight-chain or branched alkyl part, aryl having 6 to 10 carbon atoms, and also alkylcarbonyl, alkoxycarbonyl, alkylaminocarbonyl and dialkylaminocarbonyl in each case having 1 to 4 carbon atoms in the individual straight-chain or branched alkyl parts, and

• R.sup.2 represents straight-chain or branched alkyl, having 1 to 18 carbon atoms, which is optionally monosubstituted or polysubstituted, the substituents being identical or different and being cyano, in each case straight-chain or branched alkanoyl, alkoxycarbonyl or alkylcarbonyloxy in each case having 1 to 6 carbon atoms in the individual alkyl parts, and phenyl or heteroaryl which is in each case optionally monosubstituted or polysubstituted by lower alkyl and/or halogen;
• and in addition represents in each case straight-chain or branched alkenyl or halogenoalkyl in each case having 3 to 8 carbon atoms and, in the case of halogenoalkenyl, having 1 to 5 halogen atoms, or straight-chain or branched alkinyl having 3 to 8 carbon atoms, the heteroaryl when present being pyridyl, pyrimidyl, triazinyl, quinolyl, isoquinolyl, oxazolyl, isoxazolyl, oxadiazolyl, benzoxazolyl, thiazolyl, isothiazolyl, thiadiazolyl, benzthiazolyl, imidazolyl, benzimidazolyl, pyrrolyl, furanyl, thienyl, pyrazolyl or triazolyl.
