Careful ligand design led to the detection of either an unprecedented, stable, 4-membered palladacycle or off-cycle catalyst degradation product.

Glutarimidedioxime (H(2)A), a cyclic imide dioxime ligand that has implications in sequestering uranium from seawater, forms strong tridentate complexes with UO(2)(2+). The stability constants and the enthalpies of complexation for five U(VI) complexes were measured by potentiometry and microcalorimetry. The crystal structure of the 1 : 2 metal-ligand complex, UO(2)(HA)(2)·H(2)O, was determined...

AFM1-oxime-Fluoresceinamine conjugate was prepared and chracterized. .For that purpose fist was obtained and purified AFM1-oxime. UV-Vis scan spectral analysis of the obtained AFM1oxime-Fluoresceinamine conjugate was made. The activity of AFM1-oxime-Fluorescenamine conjugate was measured. It was proved that the obtained conjugate had high activity and potential possibility for detection of AFM1...

A series of 1,3-diarylprop-2-en-1-one oximes (7-12) were synthesized via reaction (1-6) with NH2OH. HCl in dry pyridine. In order to produce the required products (13-18) as anti-isomers, these (7–12) then treated acetic anhydride Different substitutes are maintained, resulting separation different yields The recently produced esters thought be useful building blocks for synthesis substituted p...

Simple amine and diamine derivatives can promote the palladium catalysed direct β-C-H arylation of aliphatic aldehydes via transient imine formation. Trifluoroacetate was shown to be crucial in promoting the reaction. Sub-stoichiometric quantities of simple N-tosylethylenediamine was shown to form a bidentate directing group with an imine linkage. Isolation of an unsymmetrical palladacycle has ...

The focus of thesis is on (i) designing of bidentate chalcogenoether ligands (ii) exploring their coordination chemistry with Pd(II), (η-benzene)Ru(II) and (ηpentamethylcyclopentadiene) Rh(III) / Ir(III) and (iii) investigating the designed metal complexes for C−C coupling reactions, NMO based oxidation of alcohols, Oppenauer-type oxidation of alcohols and transfer hydrogenation of carbonyl com...

New amphiphilic benzamidoxime, benzoxime, and aliphatic oxime derivatives of glycolipid mimetics were synthesized. The total antioxidant capacity of these amphiphilic derivatives was evaluated using DPPH assay. The observed antioxidant activity was the highest for benzamidoxime derivatives and glycolipid mimetics with two oxime functionalities, followed by benzoxime derivatives, glycolipid mime...
