In the present study we have synthesized new trinuclear complexes of alkali metal salts with interaction of stable metal chelates of violuric Acid of Ni(II) & Cu(II) having general formula [Ma(H2Va)2.(MbL)2] and [Ma(H2Va)2.(MbX)2] where Ma=Ni (II) or Cu(II) and Mb =Li + , Na & K , H2Va= deprotonated Violuric Acid , L=deprotonated 1-nitroso-2-naphthol or 8-hydroxyquinoline and, X= ClO-4 or SCN ....

The high chemical reactivity of unsaturated metal sites is a key factor for the development of novel devices with applications in sensor engineering and catalysis. Open metal sites in nanostructured coordination compounds are also central in the research for sustainable energy concepts, e.g., the efficient and sustainable production and conversion of chemical fuels. Coordinatively unsaturated m...

Lactol carbocyclisations provide a succinct method of constructing the oxabicyclo[3.2.1]octane scaffold, motif present in various natural products medicinal interest. Lactols containing an unsaturated ketone or ester were prepared by olefin cross-metathesis; electrophilic alkene derived from methyl vinyl underwent concomitant terminal α-methylenation and oxa-Michael addition to give bridged lac...

A new synthetic strategy was devised leading to the formation of complexes, such as [Au(IPr)(CH2 COCH3)]. The approach capitalizes on the formation of a decomposition product observed in the course of the synthesis of [Au(IPr)(Cl)]. A library of gold acetonyl complexes containing the most common N-heterocyclic carbene (NHC) ligands has been synthesized. These acetonyl complexes are good synthon...

Bridged bithiazoles (5,5'-ethylene-4,4'-bithiazoles) are synthesized as a good chelating agent.

A new cobalt(III) complex with a pentadentate Schiff base was synthesized using reaction of 2,2′-{(2-hydroxypropane-1,3-diyl)bis(nitriloeth-1-yl-1-ylidene)}diphenol (H3L) and cobalt(II) acetate in methanolic solution. This synthesis resulted the isolation dinuclear compound [CoIII2L2] (1), which characterized elemental analyses XRF, FTIR, TG/DSC techniques. The molecular structure confirmed sin...

While investigating the basis for marked natural asymmetries in deoxyribonucleoside triphosphate (dNTP) pools in mammalian cells, we observed that culturing V79 hamster lung cells in a 2% oxygen atmosphere causes 2-3-fold expansions of the dATP, dGTP, and dTTP pools, whereas dCTP declines by a comparable amount. Others have made similar observations and have proposed that, because O(2) is requi...

The reactions of various copper(ii) sources with 2-acetylpyridine, (py)(me)CO, and 2-benzoylpyridine, (py)(ph)CO, under strongly basic conditions have been studied and novel ligand transformations have been discovered. Reaction of Cu(ClO4)2·6H2O and (py)(me)CO in the presence of NBu4(n)OMe (1 : 1 : 1) in CHCl3 gave a mixture of [Cu2Cl2(HLA)2](ClO4)2 (1) and [Cu2Cl2(LB)2(ClO4)2] (2), where HLA i...
