Synthesis, Crystal Structure and Biological Activity of 2-Chloro-5-(((5-(1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-4-phenyl-4H-1,2,4-triazol-3-yl)thio)methyl)thiazole

The title compound 5-chloro-2-(((5-(1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-4-phenyl-4H-1,2,4-triazol-3-yl) thio) methyl) thiazole (C17H12ClF3N6S2) was synthesized, and its structure was confirmed by H-1 NMR, C-13 NMR, HRMS and X-ray diffraction. It crystallizes in the triclinic system, space group P (1) over bar with a = 8.214(5), b = 10.188(6), c = 12.378(7) angstrom, alpha = 81.679(8), beta = 87.994(8), gamma = 70.351(8)degrees, D-c = 1.572 g/cm(3), Z = 2, V = 965.2(9) angstrom(3), the final R = 0.0591 and wR = 0.1113 for 3005 observed reflections with I > 2 sigma(I). The preliminary biological test shows that the title compound possesses good herbicidal activities (80%) against rape at 200 mu g/mL.
