The title compounds 2-phenylsulfonylhydrazono-3-(3-trifluoromethylphenyl)-2(3H)-thiazoline derivatives were designed and synthesized via the reaction of thiosemicarbazides with chloroacetaldehyde, and their chemical structures were characterized by 1H NMR, 13 C NMR, elemental analysis and MS. Furthermore, 4a was characterized by single-crystal X-ray diffraction. The target compound 4a(C16H12F3N3O2S2, Mr = 399.41) crystallized in monoclinic system, P21/c space group with a = 7.7457(4), b = 13.5850(7), c = 16.5455(10) , β = 99.698(2)°, V = 1656.30(16) 3, Dc = 1.602 g/cm3, Z = 4, F(000) = 816, λ = 0.71070, μ(Mo Kα) = 0.370 mm-1, R = 0.072 and w R = 0.0867. The crystal structure of 4a revealed the cyclization of thiosemicarbazide moiety with chloroacetaldehyde at the N(1) position. The title compounds exhibited good insecticidal activity against spider mite(Tetranychus cinnabarinus Boisduval) and favorable fungicidal activity against Corynespora cassiicola.
