1-Acetyl-5-ferrocenyl-3-phenyl-2-pyrazoline
In the title compound, [Fe(C(5)H(5))(C(16)H(15)N(2)O)], the pyrazoline ring and the phenyl ring are nearly coplanar, making a dihedral angle of 6.54 (2)°, while the substituted cyclo-penta-dienyl ring is twisted out of the pyrazoline ring plane by 81.32 (1)°. The mol-ecules in the crystal structure are held together by weak C-H⋯O inter-molecular hydrogen bonds and two C-H⋯π inter-actions.

In the title compound, C(16)H(13)N(3)S, the pyrazoline ring forms dihedral angles of 6.89 (14) and 4.96 (11)° with the benzene ring and the benzothia-zole group, respectively. In the crystal, weak C-H⋯N inter-actions link the mol-ecules into chains extending along the b-axis direction.
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...

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کامل5-Hydroxy-1-(3-hydroxy-2-naphthoyl)-3,5-dimethyl-2-pyrazoline
In the title mol-ecule, C(16)H(16)N(2)O(3), intra-molecular O-H⋯O hydrogen bonds influence the mol-ecular conformation. Inter-molecular O-H⋯O hydrogen bonds [O⋯O = 2.922 (2) Å] link the mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯O inter-actions assemble these dimers into layers parallel to the bc plane.
