The invention relates to novel arylalkyl compounds of the general formula (I)
in which
m represents the numbers 0 to 5,
n represents the numbers 0 to 4,
Q represents O, S, SO or SO2,
R1 represents hydrogen or optionally substituted alkyl,
R2 represents hydrogen or optionally substituted alkyl,
X represents hydroxyl, mercapto, amino, hydroxyamino, nitro, formyl, carboxyl, cyano, carbamoyl, thiocarbamoyl, halogen, or represents an in each case optionally cyano-, halogen- or alkoxy-substituted radical from the series alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, dialkylamino, alkylcarbonyl or alkoxycarbonyl,
Y represents nitro, carboxyl, cyano, carbamoyl, thiocarbamoyl, halogen, or represents an in each case optionally cyano-, halogen- or alkoxy-substituted radical from the series alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl, and
Z represents one of the groupings below
in which
R3, R4, R5, R6 and R7 are each as defined in the description,
to processes for their preparation, to novel intermediates and to the use of the arylalkyl compounds as herbicides.
