The invention relates to novel N-alkoxycinnamamides of the formula I ##STR1## in which R.sup.1 and R.sup.2 are alkyl, alkenyl, alkynyl, alkoxyalkyl, alkoxyalkenyl, alkoxyalkynyl, trialkylsilylalkynyl or arylalkyl, aryl optionally being substituted by alkyl, alkoxy, haloalkyl, haloalkoxy, alkoxycarbonyl, halogen, cyano, nitro, alkylsulfonyl, phenyl and/or phenoxy, to processes for their preparation, to fungicidal compositions containing them, and to their use as fungicides.

Substituted N-hydroxycinnamamides, processes for their preparation,

The invention relates to plant protection agents which contain a triazole compound of the formula I ##STR1## in which Z denotes halogen, nitro, cyano, trifluoromethyl, (substituted) alkyl, (substituted) alkoxy, (substituted) alkylthio, (substituted) cycloalkyl, (substituted) phenyl or (substituted) phenoxy, Y denotes H, (substituted) alkyl, alkenyl, alkinyl or (substituted) cycloalkyl, X denotes hydroxyl, alkyl, cycloalkoxy, phenoxy, alkenyloxy, alkinyloxy, (substituted) alkoxy, (substituted) alkylthio or a radical of the formulae ##STR2## and n denotes 0, 1, 2 or 3, and salts thereof, and to new compounds of the formula I as defined above, Y denoting CCl.sub.3 or CHCl.sub.2 in the event that X denotes (C.sub.1 -C.sub.4)-alkyl, and compounds in which

Plant protection agents based on 1,2,4-triazole derivatives and also new

1,2,4-Triazole derivatives of the formula ##STR1## in which R.sub.1 denotes methyl or optionally substituted phenyl,

1,2,4-Triazole derivatives

A 5-methyl-isoxazole-4-carboxylic acid anilide is prepared by heating an acetoacetic acid anilide with an orthoformic acid ester and a carboxylic acid anhydride, isolating the resulting 2-alkoxymethylene-acetoacetic acid anilide and then treating it with hydroxylamine in an organic solvent. The compounds of the invention have anti-inflammatory and analgetic activity.

5-Methyl-isoxazole-4-carboxylic acid anilides

A 2-hydroxyethylidene-cyano acetic acid anilide is prepared by heating an acetoacetic acid anilide with an orthoformic acid ester and acetic anhydride, isolating the resulting 2-alkoxymethylene-acetoacetic acid anilide and treating it with hydroxylamine and the isoxazole so obtained with a base, and optionally reacting the resulting alkali metal or ammonium salt with a mineral acid or a strong organic acid. The compounds of the invention have anti-inflammatory and analgesic activity.
