Abstract:

With nitrosation of the corresponding 1-R-3-methylpyrazole-5-one (R = C4H9, C5H11, C6H13, C7H15, C8H17, C6H5) in acidic aqueous methanolic medium at 0-5 °C a series of 1-alkyl-3-methyl-4-hydroxyimino-2-pyrazolin-5-ones with a yield of 72-85% were synthesized. The compounds are soluble in CHCl3, C2H4Cl2, C6H5CH3, i-C4H9OH, CCl4, C2H5OH, slightly soluble in C6H14, H2O. They can be recrystallized from a mixture of C6H14: C6H5CH3 = 5: 1 or isooctane. The structure of the compounds was confirmed by the data of ECR, IR, Raman spectroscopy and TLC data. The interphase distribution of oxyiminopyrazolo

Abstract:

Objective: Pyrazolines are known to exhibit different biological and pharmacological properties such as anticancer, antibacterial, antifungal and antitubercular activities. Chalcones with an enone group between two aromatic rings exhibit remarkable pharmacological activities such as antiinflammatory, antibacterial, antitumor, antifungal, and antimalarial activity. A series of pyrazolines from chalcones have been synthesized and evaluated for antitubercular and cytotoxic activity studies.Methods: Chalcones [3-substituted phenyl-1-(p-tolyl)prop-2-en-1-one] were synthesized from various substitut

Abstract:

A cloud point extraction method was presented for preconcentration of copper in various samples. After complexation with 4-Amino-2,3-dimethyl-1-phenyl-3-pyrazoline-5-one (ADPP) or N-Benzoyl-N-phenylhydroxylamine (BPA) in water, analyte ions are quantitatively extracted to the phase rich in Triton X-114 after centrifugation. 2.0 mol L-1 HNO3 solution in methanol was added to the surfactant-rich phase prior to its analysis by flame atomic absorption spectrometry (FAAS). The adopted concentrations for ADPP, Triton X-114, HNO3 and parameters such as bath temperature, centrifuge rate and time were

Abstract:

The extraction properties of solutions of 4-benzoyl- and 4- (3-nitrobenzoyl) -1-hexyl-3-methyl-2-pyrazolin-5-ones in chloroform were studied. The pH dependence of the degree of extraction is S-shaped. Ions Cu2+, Pb2+, Zn2+, Ni2+, Co2+, Mn2+, Cd2+, Ca2+, Mg2+ are extracted in the form of complexes with the ratio M (II): reagent determined by the equilibrium shift method equals to 1: 2. A lower equilibrium pH than the initial value indicates a cation-exchange extraction mechanism. The introduction of an electronegative nitro group into the benzoyl fragment of the reagent led to a shift in the pH

Abstract:

The title compound, [Co(C17H13N2O2)2(C2H5OH)2], is a CoIIcomplex with two 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5-olate (BMPP) ligands and two coordinating ethanol molecules. In the asymmetric unit, there are two half molecules, with the CoIIatoms located on inversion centres. The two cobalt complexes have slightly different geometries and in one, the ethyl group of the ethanol is disordered over two sets of sites [occupancy ratio 0.757 (7):0.243 (7)]. Each BMPP ligand is deprotonated with the negative charge delocalized. The hydroxy group of each ethanol molecule forms hydrogen bonds with a
