Abstract
NEW MATERIAL:A pyrazole derivative expressed by formulaI(X is 2W8C unsaturated hydrocarbon group).
EXAMPLE: 4-(2,4-Dichloro-3-methylbenzoyl)-1,3-dimethyl-5-allyloxypyrazole.
USE: A herbicide, usable by the pre- or post-emergence soil treatment of weeds particularly in paddy fields substantially without damaging paddy rices, and characterized by the three substituent groups on the benzoyl group at the 4-position in the pyrazole ring and an unsaturated hydrocarbon group at the 2-position through the oxygen atom.
PROCESS: A 5-hydroxypyrazole derivative expressed by formulaI' is reacted with a halogen compound expressed by formula II (Hal is Cl or Br) to give the compound expressed by formulaI.
