摘要：
The title compound N-(7-chloro-5-ethoxy-2H-[1,2,4]thiadiazolo[2,3-a]pyrimidin- 2-ylidene)- 2-(2,4-dichlorophenoxy)propanamide 3 has been synthesized through using bromine as cyclic reagent in 63% isolated yield. Suitable single crystals for X-ray diffraction were obtained by recrystallization from the mixture solvents at room temperature. Crystallographic data of 3: C16H13- Cl3O3S, Mr = 447.71, triclinic, space group P, a = 8.7461(8), b = 9.9560(10), c = 11.8572(11) , α = 94.341(2), β = 94.683(2), γ = 112.929(2)o, Z = 2, V = 941.21(15) 3, Dc = 1.580 g/cm3, F(000) = 456, R = 0.0794, wR = 0.2056 and μ(MoKα) = 0.623 mm-1. The title compound 3 was found to be effective in herbicidal activity.
