The title compounds(Z)-3-(2-(3-chloropyridin-2-yl)hydrazono)indolin-2-one(A) and 7-bromo-(Z)-3-((4-pyridinyl)carboxlichydrazono)-2-indolinone(B) have been synthesized and structurally determined by ele... The title compounds(Z)-3-(2-(3-chloropyridin-2-yl)hydrazono)indolin-2-one(A) and 7-bromo-(Z)-3-((4-pyridinyl)carboxlichydrazono)-2-indolinone(B) have been synthesized and structurally determined by elemental analysis and single-crystal X-ray diffraction studies.Compound A(C13H8ClN4O) belongs to the orthorhombic crystal system,space group Pca21 with a = 20.799(4),b = 4.9312(10),c = 11.764(2),V = 1206.6(4)3,Mr = 271.68,Dc = 1.496 g/cm3,μ = 0.313 mm-1,F(000) = 556,Z = 4,the final R = 0.0346 and wR = 0.0831 for 2683 observed reflections with I 2σ(I).Compound B(C14H9BrN4O2) belongs to the triclinic crystal system,space group P1 with a = 6.6834(13),b = 7.0727(14),c = 14.285(3),α = 95.56(3),β = 99.00(3),γ = 102.95(3)°,V = 643.8(2)3,Mr = 345.16,Dc = 1.780 g/cm3,μ = 3.203 mm-1,F(000) = 344,Z = 2,the final R = 0.0487 and wR = 0.1167 for 2334 observed reflections with I 2σ(I).The preliminary herbicidal bioassay reveals that compounds A and B have some inhibition both in vivo and in vitro against AHAS. 展开更多

Two novel compounds 1-(4-fluorobenzyl)-4-chloro-(Z)-3-benzoylhydrazono-2-indolinone(1) and 1-(4-methoxybenzyl)-(Z)-3-benzoylhydrazono-2-indolinone(2) were synthesized and their crystal structures were dete... Two novel compounds 1-(4-fluorobenzyl)-4-chloro-(Z)-3-benzoylhydrazono-2-indolinone(1) and 1-(4-methoxybenzyl)-(Z)-3-benzoylhydrazono-2-indolinone(2) were synthesized and their crystal structures were determined by single-crystal X-ray diffraction.Compound 1(C22H15ClFN3O2) crystallized in the triclinic system,space group P1·with a=0.94198(19) nm,b=1.4339(3) nm,c=1.5018(3) nm,α=101.58(3)°,β=102.96(3)°,γ=102.73°,V=1.8602(6) nm3,Mr=407.82,Dc=1.456 g/cm3,μ=0.240 mm-1,F(000)=840,Z=4,R1=0.0442 and wR2=0.1064.Compound 2(C23H19N3O3) crystallized in the triclinic system,space group P1·with a=1.0022(2) nm,b=1.0192(2) nm,c=1.0461(2) nm,α=99.86(3)°,β=117.30(3)°,γ=94.13(3)°,V=0.9215(3) nm3,Mr=385.41,Dc=1.389 g/cm3,μ=0.094 mm-1,F(000)=404,Z=2,R1=0.0403 and wR2=0.1142.The preliminary herbicidal activities of the two compounds were also evaluated. 展开更多
