Abstract

NEW MATERIAL:Δ2-1,2,4-Triazolin-5-ones of formula I (R1 is H, or 1W4C alkyl; X is H, halogen, 1W4C alky, 1W6C alkyloxy, or 2W4C alkenyloxy).
EXAMPLE: 1-(2,4-Dichloro-5-isopropoxyphenyl)-3-methyl-Δ2-1,2,4-triazolin-5-one.
USE: Intermediate of agricultural and horticultural herbicide.
PROCESS: The compound of formula I is prepared by (1) reacting a compound of formula II with a compound of formula III (Y is O or S) in an inert solvent under heating, and (2) cyclizing the resulting compound of formula IV, if necessary after separating from the raction product, in the presence of a base (pref. an inorganic base such as caustic soda, etc.). The compound of formula I can be converted to the compound of formula V (R2 is 1W12C alkyl, etc.) which is useful as a herbicide, by reacting with a compound of formula R2Z (Z is halogen, etc.).
