In the title molecule, C(9)H(3)Cl(3)O(3), there are three short interactions involving the benzene H atoms and the chloro-formyl Cl atoms. In the crystal, mol-ecules stack along the a axis with no significant non-bonded inter-actions.
The title compound, [Cu(2)(C(31)H(30)Cl(2)N(4)O(4))Cl(2)]·CH(3)CN, was synthesized by cyclo-condensation between N,N'-bis-(2-fur-yl)-N,N'-bis-(3-formyl-5-chloro-salicylaldehyde)ethyl-enediamine and 1,3-diamino-propane in the presence of Cu(II) ions. It is an unsymmetrical dinuclear Cu(II) complex. The coordination geometry for each Cu(II) atom can be discribed as distorted square-pyramidal. The...
Here we describe the efficient synthesis of alkyl 4-arylsubstituted-6-chloro-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylates and 4-arylsubstituted-4,7-dihydro-furo[3,4-b]pyridine-2,5(1H,3H)-diones via microwave-accelerated reaction of alkyl 4-arylsubstituted-2-methyl-6-oxo-1,4,5,6-tetrahydro-3-pyridinecarboxylates with the appropriate reagents. This eco-friendly approach to these valuable ...
In this study, a series of four formyl-substituted chloro-bridged iridium(iii) dimers were prepared. Their absorption, photophysical and electrochemical properties were studied in dichloromethane solution. It was found that as the formyl content increased on the cyclometalating ligands, emission unexpectedly became brighter. Organic light-emitting diodes (OLEDs) were fabricated using each of th...
In the present work, N-[2-(thienyl)-2-(chlorobenzyloxyimino)ethyl]enoxacin derivatives (4a-f) were synthesis by the reaction of enoxacin with 2-bromo-1-(thiophen) ethanone O-2-chlorobenzyl oxime derivatives (3a-f) in DMF in the presence of NaHCO3 at room temperature. The synthesized compounds were tested in vitro on human tumor cell lines. Preliminary screening showed 4b and 4e demonstrated sig...
Purpose: The article is aimed to synthesize,characterize and screening the biological activity of a series of Synthesis of 1-(2-(3-(3-chloro-1-(4-substituted phenyl)-4-tetrazole-2-yl)-1H-indol-1-yl)acetyl)-4-(2-(4substituted phenyl)hydrazono)-3-(trifluoromethyl)-1H-pyrazol-5(4H)-one 4(a-f). Indole-3-carbaldehyde and chloro ethyl acetate were dissolved in DMF. To this reaction mixture anhydrous ...
