1-Acetyl-3-(4-chlorophenyl)-5-(4-fluorophenyl)-2-pyrazoline
In the title mol-ecule, C(17)H(14)ClFN(2)O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chloro-benzene and 4-fluoro-benzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak inter-molecular C-H⋯O hydrogen bonds help stabilize the crystal structure.
متن کاملBenzyl 5-ferrocenyl-3-(4-methylphenyl)-2-pyrazoline-1-dithiocarboxylate
In the title compound, [Fe(C(5)H(5))(C(23)H(21)N(2)S(2))], the cyclo-penta-dienyl rings of the ferrocenyl unit deviate slightly from the eclipsed form. In the pyrazoline ring, the N atom bonded to S-benzyl dithio-carbazate exhibits unconventional sp(2)-hybrid character in order to form an extended conjugated system. The pyrazoline ring displays an envelope conformation. The mol-ecules are linke...
متن کامل1-{3-[1-(Hydroxyimino)ethyl]-4-methyl-1H-pyrazol-5-yl}ethanone
In the title compound, C(8)H(11)N(3)O(2), the oxime and the acetyl groups adopt a transoid conformation, while the pyrazole H atom is localized in the proximity of the acetyl group and is cis with respect to the acetyl O atom. In the crystal, dimers are formed as the result of hydrogen-bonding inter-actions involving the pyrazole NH group of one mol-ecule and the carbonyl O atom of another. The...
متن کاملIsoquinoline Promoted Synthesis of alkyl 2-(1-alkyl-5-oxo-3-phenyl-2-thioxotetrahydro-4H-imidazol-4-yliden) acetate derivatives
Derivatives of thiazolidinone ring systems are known to act as anti-HIV infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. Due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. Imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...
متن کامل1-Acetyl-3-ferrocenyl-5-(2-nitrophenyl)-2-pyrazoline
In the title compound, [Fe(C(5)H(5))(C(16)H(14)N(3)O(3))], the pyrazoline ring and the substituted cyclo-penta-dienyl ring are nearly coplanar, with a dihedral angle of 8.17 (2)°, while the nitro-substituted benzene ring is twisted out of the pyrazoline ring plane by 70.76 (1)°. The mol-ecules in the crystal structure are held together by three inter-molecular C-H⋯O hydrogen bonds. There is als...
