Some new substituted 3-aroyl flavanones (4a-i) were synthesized by condensation of substituted dibenzoyl methanes (3a-b) with aromatic aldehydes in ethanol containing small amount of piperidine. The structures of 13 compound few compounds were confirmed on the basis of LR., P.M.R.; C and Mass spectra and chemical analysis. The substituted 3-aroyl flavanones showed diverse biological activity. © Research India Publications.

Work presented is a preliminary investigation of water purification using clay filters. This work was carried out to determine the efficiency of clay pots (as a filter) in removing water impurities. Filters and the related parts were fabricated and its efficiency in removing EC, TDS, TSS, hardness, BOD, COD, and some ions like Ca, Mg, Na, K, chloride, sulphate, Oil and grease was measured by passing water through the clay filters. The clay filters showed excellent efficiency in removal of TSS, BOD, COD, Oil and grease, sodium and potassium and negligible potential to remove hardness, EC, TDS, chloride and sulphate of water.

The interaction between Th(III), Sm(III), Nd(III) and Pr(III) Metal Ions And 2-Mercapto-4-(4'-Aminophenyl)-6-(2'-Hydroxy-5'-Bromophenyl)Pyrimidine[M4AHBP](L1) and 2-Mercapto-4-(2'-Chlorophenyl)-6-(2'-Hydroxy-5'-Bromophenyl)Pyrimidine[M2CHBP](L2) have been studied at 0.1 M Ionic Strength in 70 % Dioxane-water mixture by Bjerrum method as adopted by Calvin and Wilson. It is observed that Th(III), Sm(III), Nd(III) and Pr(III) Metal ions form 1:1 and 1:2 complexes with ligands (L1 & L2). The data obtained were used to estimate and compare the values of proton-ligand stability constant (pK) and metal-ligand stability constants (log k). From estimated data (pK and log k), the effects of substituents were studied.

Ultrasonic velocities and densities of 3-(2-hydroxyl-4-methyl phenyl)-5-phenyl isoxazoline (L1) and 1-phenyl-3-(2-hydroxyl-3-nitro-4-methyl phenyl)-5-phenyl pyrazoline (L2)) at different concentrations in dioxane. Different acoustic properties like partial molal volume, adiabatic compressibility, apparent molal compressibility, intermolecular free length, specific acoustic impedance and relative association etc., have been determined. These parameters obtained have been interpreted in terms of solute-solute interactions. Effect of L1) & L) ligand and its complexes on germination of seeds.

A Simple and convenient protocol is described for preparation of some new 5-(2'- hydroxy-3',5'-dichlorophenyl)-4-(4'-chlorobenzyl)-2-amino-1,3-thiazole and 5-(2'- hydroxy-3',5'-dichlorophenyl)-4-(4'-chlorobenzyl)-2-aminophenyl-1,3-thiazole, were synthesized by refluxing dibrominated chalcone with thiourea or N-phenyl thiourea in good yields. The newly synthesized titled compounds were screened for their antibacterial activities against pathogens such as staphylococcus aureus, p.aeruginosa, almonella typhi. Some of the compounds displayed pronounced biological activity. All these compounds have been characterized on the basis of their UV, IR and NMR spectral results.

The synthesis, spectral analysis and effect on some crop plants by some 4-Aroylisoxazoles with 3-aroylflavone on treatment with NH2OH.HCl. We got two series while carried out in different aromatic acids. In series, we got 3-(2-hydroxy-3,5-dichlorophenyl)-4-anisoyl-5-(3-nitro phenyl) isoxazole and 3-(2-hydroxy-3,5-dichlorophenyl)-4-benzoyl-5-(3'-nitrophenyl) isoxazole. It has been revealed that, the use of piperidine in DMSO as the solvent in the above reaction influences the rate of the reaction and also the yield of the products.. All these compounds have been analyzed by UV, IR and NMR for structure. The newly synthesized chlorosubstituted isoxazoles were studied. © 2011 RASAYAN. All rights reserved.

The synthesis, spectral analysis and biological activities of some 4-phenyl-2-hydroxy-chlorosubstituted-2-imino-1, 3-thiazene with phenyl thiourea and diphenyl thiourea have been carried out in two series. In series I we got 4-(2-hydroxy-3,5-dichlorophenyl-6-(ethyl)-2-iminophenyl-1,3-thiazene and 4-(2-hydroxy-3,5-dichlorophenyl-6-(ethyl)-2-iminophenyl-3-phenyl-1,3-thiazene(3a-6a) from 2-hydroxy-3,5-dichloroacetophenone from phenyl thiourea and in series II 4-(2-hydroxy-3,5-dichlorophenyl)-6-(hexyl)-2-iminophenyl-1,3-thiazene and 4-(2-hydroxy-3,5-dichlorophenyl)-6-(hexyl)-2-iminophenyl-3-phenyl-1,3-thiazene(3b-6b) were synthesized from diphenyl thiourea. All these compounds have been analyzed by UV, IR and NMR for structure assignment. The Antibacterial activities of these compounds were studied.
