Abstract
NEW MATERIAL:Isoxazole derivatives of formula I [R is H, alkyl, aryl; R1 is H, alkyl; R2 is formula II (R3, R4 are H, alkyl, alkenyl, aralkyl, aryl, alkylthio, alkoxy, or may incorporate with each other or together with hetero atom to form N-containing ring), formula III (R5 is alkyl, alkenyl, alkynyl, aralkyl, aryl; Y is oxygen or sulfur atom), X is H, halogen, and may incorporate with R to form alkylene group].
EXAMPLE: 1-Methyl-3-(5-t-butyl-3-isoxazolyl)urea.
USE: Strong herbicide.
PREPARATION: In an example, the reaction of an isoxazolylamine derivative of formula IV with an isocyanate ester of formula V gives the objective compound of formula I
