摘要：

The title compound methyl(E)-α-(methoxyimino)-2-((4-(3-chloro-5-(trifluoromethyl) pyridine-2-yl)phenoxy)methyl)benzeneacetate(C23 H18 ClF3 N2 O4) has been synthesized and structurally characterized by 1 H and 13 C NMR, and HRMS. Its absolute molecular configuration was investigated by X-ray crystallography. The crystal crystallizes in monoclinic system, space group P21/c with a = 15.0928(7), b = 19.6070(10), c = 7.5535(5) ?, β = 98.176(5)°, V = 2212.6(2) ?3, Z =4, Dc = 1.438 g/cm3, F(000) = 984, μ(Mo Kα) = 0.231 mm-1, the final R = 0.0619 and wR = 0.1681 with 4034 observed reflections with I > 2σ(I). The title compound has significant inhibitory rate against broadleaf weeds. They are all 100% under the dose of 37.5 g.a.i/ha, which was better than mesotrione.
