NOVEL HERBICIDAL PYRIMIDINE DERIVATIVE HAVING A PHENYLIMIDOESTER GROUP, PROCESS FOR PREPARATION THEREOF AND USE THEREOF AS A HERBICIDE

摘要

Pyrimidine derivative including phenylimino ester structure of general formula(I) is prepared by condensing a compound of general formula(II) and that of general formula(III) in metal salts and solvent. In the formula, R1 is alkyl of C1-C4, alkenyl of C1-C4, acetyl, alkylsulfonyl, hetero arylmethyl and R2 is hydrogen atom, alkyl of C1-C4, alkenyl of C1-C4. R3 is hydrogen, methyl, halogen, alkoxy of C1-C4, alkintino of C1-C4, cyano, alkoxycarbonyl of C1-C4. The produced pyrimidine derivative has excellent weedicide.
