Abstract
NEW MATERIAL:A compound of formulaI[R1 is H, alkyl, alkenyl; R2 is H, halogen; R3 is -OR4 (R4 is H, cation, alkyl), -N(R5) (R6) (R5, R6 are H, alkyl, alkenyl, phenyl); X is halogen, nitro, alkyl, alkoxy; n is 0, 1W3; Y is H, cation, residue of organic acid, phenyl, benzyl].
EXAMPLE: Ethyl 4-(2,4-dichlorobenzoyl)-5-hydroxy-1-methyl-3-pyrazolylacetate.
USE: Herbicide: it is excellent as a selective herbicide for soil treatme"nt.
PREPARATION: The rearrangement of a compound of formula II (a novel compound) is effected in the presence of a basic alkali or alkaline earth metal or aluminum trichloride to give a compound of formulaIwhere R2 and Y are H. The compound of formula II is obtained by reaction between a compound of formula III which are novel except a few ones and benzoyl halide.
