摘要:
Novel intermediates for fungicides, comprising fluorocyclopropyl derivatives of the formula ##STR1## in which R represents alkyl, optionally substituted aryl or optionally substituted aralkyl,X represents hydrogen, chlorine or bromine andR.sup.1 represents hydroxyl, alkoxy, alkyl or halogen.
摘要:
New fluorinated tertiary butylamines of the formula ##STR1## are prepared from halogenated pivalic acid halides by a reaction sequence which comprises preparing the fluorinated pivalic acid and decomposition of the azide to the corresponding isocyanate. The isocyanate can be converted to the fluorinated tertiary butylamine acid addition salt by acid hydrolysis or directly to the amine by treatment with base. In addition, the present amines can be prepared by reaction of a pivalic acid amide with hypochlorite. The new butylamines can be used in the preparation of benzoic acid amides having insecticidal action.
摘要:
The present invention relates to new 5-trihalogenomethyl-isoxazoles of the formula (I) ##STR1## in which x represents 1, 2 or 3, and a process for their preparation by reacting the corresponding trichloromethylisoxazole with a fluorinating agent.
摘要:
Arthropodically active 3-halogenoalkyl-1-arylpyrzoles of the formula ##STR1## in which R.sup.1 represents halogenoalkyl,R.sup.2 represents cyano, or represents hydroxycarbonyl, or represents carbamoyl or thiocarbamoyl, or represents alkoxycarbonyl, N-alkylcarbamoyl or N,N-dialkylcarbamoyl, or represents alkenyloxycarbonyl, N-alkenylcarbamoyl or N,N-dialkenylcarbamoyl, or represents alkinyloxycarbonyl, N-alkinylcarbamoyl, N,N-dialkinylcarbamoyl or N-arylcarbamoyl, or represents alkylcarbonyl, halogenoalkycarbonyl or cycloalkylcarbonyl,R.sup.3 represents hydrogen, alkyl, halogenoalkyl or cycloalkyl andAr represents substituted phenyl, with the exception of the 2,4-dinitrophenyl radical.
摘要:
3-Fluoro-2-(fluoromethyl)-propene is prepared in a simple manner and in good yields by reacting 3-chloro-2-(chloromethyl)-propene with a fluorinating agent. The present invention also relates to 3-fluoro-2-(chloromethyl)-propene, an intermediate product in this process.
摘要:

摘要:
A cyclopropylamine of the formula ##STR1## and a process for producing the same by reacting a cyclopropylcarboxylic acid amine of the formula ##STR2## with sulphur tetrafluoride in anhydrous hydrogen fluoride. The cyclopropylamine is useful in the preparation of benzoic acid amides which have an insecticidal action.
