ABSTRACT A novel N-aroyl diketone derivative, 3-(2-chloro-6-fluorophenyl)-4-(2-oxooxazolidine-3-carbonyl)-5-methylisoxazole (C14H10ClFN2O4, Mr=324.69), was designed via fragment analysis and coupling strategy that led to highly potent and bio-selective herbicide. The title compound was prepared by a multistep-reaction, including nucleophilic addition and N-acylation reaction using 2-chloro-6-fluorobenzaldehyde as the starting materials in 83.4% yield. The product was characterized by infrared, proton nuclear magnetic resonance, Carbon-13 nuclear magnetic resonance, human resource management system, and X-ray diffraction. The title compound crystallized in the monoclinic system, space group P21/n with a=10.7119(4) ?, b=17.5875(7) ?, c=11.5151(7) ?, b=100.927(2)°, Z=8, V=2870.0(2) ?3, F(000)=1328, Dc=1.503 Mg/m3, crystal size: 0.130 × 0.120 ×0.100 mm. The herbicidal activity was tested against the gramineous weed Echinochloa crus-galli and broadleaf Abutilon juncea.
