Microwave Assistant Synthesis, Crystal Structure and Biological Activity of A 1,2,4-Triazole Compound

Abstract

The title compound (C₁₇H₁₄F₂N₄SO) were synthesized and recrystallized from CH₃CN. The compound was characterized by ¹H-NMR, FTIR, MS, HRMS and X-ray diffraction. The compound crystallized in the Monoclinic space group C2/c with a = 27.532(6), b = 8.9596(18), c = 14.609(3) Å, α = 90, β = 112.59(3), γ =90°, V = 3327.1(12) Å3, Z = 8 and R = 0.0327 for 2596 observed reflections with I > 2σ(I). X-ray analysis reveals that not only intermolecular N–H•••N interactions, but also C-H•••π stacking interactions exist in the adjacent molecules. The biological activities results showed that it exhibited significant herbicidal activity towards Brassica napus.
