Abstract

NEW MATERIAL:A Δ2-1,2,4-triazolin-5-one expressed by formula I (R1 is H, 1W4C lower alkyl or lower alkenyl; X is 1W4C lower alkyl or 1W4C lower alkyloxy).
EXAMPLE: 1-(2,4-Dichloro-5-methoxyphenyl)Δ2-1,2,4-triazolin-5-one.
USE: A herbicide effective for controlling annual and perennial weeds in a paddy field, a plowed field, a tree garden and damp ground, particularly weeds before germination and at the beginning stage of generation.
PROCESS: A compound of formula II is reacted with a compound of formula III in an inert solvent under heating to give a compound of formula IV, which is subjected to ring closure in the presence of a base to form a compound of formula V. The compound of formula V is then reacted with a compound of formula VI (X is halogen) to afford the compound of formula I.
