Spectroscopic, thermal and magnetic properties of some transition metal complexes derived from 1-Phenyl-3-Substituted-4-Nitroso-5-Pyrazolones
Complexes derived from some 1-Phenyl-3-methyl-4-nitroso-5-pyrazolone (L1), 1,3-diphenyl-4nitroso-5-pyrazolone (L2) and 1-phenyl-3-anilino4-nitroso-5-pyrazolone (L3) with Mn, Co, Ni, Cu and Zn metal ions have been prepared. Structural investigation of the ligands and their complexes has been made based on elemental analysis, infrared (FT-IR), ultraviolet and visible spectra (UV-Vis.), proton nuc...
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 کاملSynthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
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 کامل4-[(2-Benzoyl-4-chlorophenyl)diazenyl]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C(23)H(17)ClN(4)O(2), the amino H atom forms an intra-molecular hydrogen bond to the exocyclic carbonyl O atom as well as to the O atom of the benzoyl group.
متن کاملAn easy direct arylation of 5-pyrazolones
A mild, efficient and catalytic ligand-free method for the direct arylation of 5-pyrazolones by Pd-catalyzed C-H bond activation is reported. The process smoothly proceeds and yields are moderate to excellent.
