Abstract
2,2-Difluorocyclopropyl derivatives of the formula ##STR1## in which R represents alkyl, optionally substituted aryl or optionally substituted aralkyl and X represents hydroxymethyl, 2-hydroxyethyl, isocyanato, amino, amino hydrohalide or a radical of the formula --CO--R.sup.1, where R.sup.1 represents hydrogen, hydroxyl, alkoxy, alkyl, halogen or amino, are intermediates for fungicides.
Claims5
A 2,2-difluorocyclopropyl derivative of the formula ##STR71## in which R represents alkyl having 1 to 4 carbon atoms, or phenyl which can be monosubstituted to trisubstituted by identical or different substituents from the group consisting of halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, alkylthio having 1 to 4 carbon atoms, halogenoalkyl having 1 to 2 carbon atoms and 1 to 5 identical or different halogen atoms, halogenoalkoxy having 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms, halogenoalkylthio having 1 to 2 carbon atoms and 1 to 5 identical or different halogen atoms, alkoximinomethyl having 1 to 4 carbon atoms in the alkyl moiety and 1 to 4 carbon atoms in the alkoxy moiety, phenoximinoalkyl which has 1 to 4 carbon atoms in the alkyl moiety and which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen, phenyl which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen, and/or phenoxy which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen,
- or
- R represents benzyl which can be monosubstituted to trisubstituted in the phenyl moiety by identical or different substituents from the group consisting of halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, alkylthio having 1 to 4 carbon atoms, halogenoalkyl having 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms, halogenoalkoxy having 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms, halogenoalkylthio having 1 or 2 carbon atoms and 1 to 5 identical or different halogen atoms, alkoximinoalkyl having 1 to 4 carbon atoms in the alkyl moiety and 1 to 4 carbon atoms in the alkoxy moiety, phenoximinoalkyl which has 1 to 4 carbon atoms in the alkyl moiety and which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen, phenyl which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen, or phenoxy which is optionally substituted by alkyl having 1 or 2 carbon atoms and/or halogen,
- and
- R.sup.1 represents alkyl having 1 to 4 carbon atoms.
