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： C 16H13C13O3S, Mr = 447.71, triclinic, space group P1, a = 8.7461（8）, b = 9.9560（10）, c = 11.8572（11） A, a = 94.341（2）, β = 94.683（2）, γ = 112.929（2）°, Z = 2, V= 941.21（15） A^3, Dc = 1.580 g/cm^3, F（000） = 456, R = 0.0794, wR = 0.2056 andμ（MoKa） = 0.623 mm^-1. The title compound 3 was found to be effective in herbicidal activity.
