摘要

Compounds of the formula (I) in which R represents halogen, C1-C6-alkyl, C1-C3-haloalkyl, C1-C2 alkoxy, NO2 or S-CH3, R1 represents hydrogen or C1-C6-alkyl, R2 represents C1-C6-alkylamino, C3-C8-alkenylamino, N,N-di-(C1-C6-alkylamino), C5-C8-cycloalkylamino or a saturated N-heterocycle having from 4 to 8 C-atoms altogether of which 1 or 2 may stand in the side chain and in which one CH2group of the cycle may be replaced by oxygen or sulfur, R3 represents C1-C6-alkyl, X is oxygen or sulfur and n is zero or a whole number in the range of from 1 to 3 exhibit a good herbicidal effect on some economically important weed grasses and dicotyledonous weeds and simultaneously they have excellent insecticidal and acaricidal properties.
