5-(2,4-Dichlorophenyl)-3-(4-nitrophenyl)-1,2,4-oxadiazole
In the title compound, C(14)H(7)Cl(2)N(3)O(3), the dichloro-phenyl and nitro-phenyl rings form dihedral angles of 5.4 (2) and 4.0 (2)°, respectively, with the oxadiazole ring. The nitro group is twisted out of the attached benzene ring by a dihedral angle of 10.4 (3)°. In the crystal, mol-ecules are linked into a chain along the a axis by C-H⋯N hydrogen bonds.

In the title compound, C(25)H(21)F(2)N(3)O(3)S, the morpholine ring adopts a chair conformation. The 1,3,4-oxadiazole-2(3H)-thione group makes dihedral angles of 78.69 (8), 53.56 (7) and 55.30 (9)° with the benzene rings. In the crystal, O-H⋯O, C-H⋯S and C-H⋯F hydrogen bonds linked the mol-ecules into layers lying parallel to the ab plane. Weak C-H⋯π inter-actions also occur.
متن کاملSynthesis and antimicrobial activity of some 1-(2,4-dinitrophenyl)-3-(3-nitrophenyl)-5-(4-substituted phenyl)-4-bromo-2-pyrazolines and 1-(2,4-dinitrophenyl)-3-(3-nitrophenyl)-5-(4-substituted phenyl)-2-pyrazolin-4-ones.
A series of 1-(2,4-dinitrophenyl)-3-(3-nitrophenyl)-5-(4-substituted phenyl)-2-pyrazolin-4-ones (4a-e) have been synthesized by the oxidation of 1-(2,4-dinitrophenyl)-3-(3-nitrophenyl)-5-(4-substituted phenyl)-4-bromo-2-pyrazolines (3a-e) with dimethylsulfoxide. The structure has been established on the basis of spectral data (IR,1H NMR). The synthesized compounds have been screened in vitro fo...
