Document Type and Number:

Japanese Patent JPH01199950

Kind Code:

A

Abstract:

NEW MATERIAL:The compound of formula I (R is H or methyl; the substitution position of the cyclohexane ring is 4 or 5 position of the pyrazole ring) or its salt.

EXAMPLE: 2-[1-(3-Chloro-2-propenyloxyimino)propyl]-5-(1-methyl-1H-pyrazol-4-yl) cyclohexane-1,3-dione.

USE: A selective herbicide. It has high selectivity between broad leaved plants and gramineous plants and exhibits selectivity to crops such as leguminous crops, cotton, beet, sunflower, etc.

PREPARATION: The compound of formula I can be produced by reacting a compound of formula II with the compound of formula Cl-CH=CH-CH2-ONH2 in a solvent such as methanol at a temperature between 0°C and the boiling point of the solvent.
