pyrimidine-5-carbonitrile Ι were employed as the starting materials to synthesize a novel series of 1,2,4-triazole derivativescontaining fluorine, phenyl sulfonyl and pyrimidinemoieties Ⅳ-1∼Ⅳ-39. The preliminary bioassay indicated that many newly synthesized compounds exhibited moderate to good herbicidalactivities against the monocotyledons (Echinochloa crusgalli, Sorghum bicolor) and dicotyledons (Raphanus sativus

Abstract A facile approach for the synthesis of pyrimidine derivatives containing 1,2,4-triazole moiety via the reaction of substituted 2-phenoxypropane hydrazide with ethyl-N-(5-cyano-2-alkylthio-5-cyano-6-methylthiopyrimidin-4-yl) formimidate in refluxing 2-methoxyethanol is reported. The structures of the title compounds were identified by 1H NMR, 13C NMR, and HRMS. The configuration of compound
