Abstract
Insecticidal and acaricidal novel substituted furazans of the formula ##STR1## n which R1 and R2 are identical or different and represent hydrogen, halogen, alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogenoalkylthio or optionally substituted aryloxy, or
R1 and R2 together represent an optionally substituted alkylene radical which is interrupted by 1 or 2 oxygen atoms or is bonded to the phenyl radical via 1 or 2 oxygen atoms,
R3 and R4 are identical or different and represent hydrogen, halogen, alkyl, alkoxy, halogenoalkyl or halogenoalkoxy,
R5 represents optionally substituted cycloalkyl, and
X represents oxygen or sulphur.
Intermediates of the formula ##STR2## in which B is --NH2, --NO2 or --NCX,
R3 and R4 are identical or different and represent hydrogen, halogen, alkyl, alkoxy, halogenoalkyl or halogenoalkoxy,
R6 represents 2,2-difluoro-1-methylcycloprop-1-yl or the ##STR3## radical, Y represents hydrogen, methyl, fluorine or chlorine, and
Y1 and Y2 are identical or different and represent fluorine or chlorine,
are also new.
