The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

Photo-controlled metal-ion (Zn(2+) and Cd(2+)) release in aqueous micelle solution (tris-HCl, pH = 7.4) has been described using 2-((2-mercaptophenylimino)methyl) phenol as ligand. It is found that both the ligand-Zn complex (1) and the ligand-Cd complex (2) are stable in micelle solution, and Zn(2+) (Cd(2+)) can be released from the complex with 365 nm light trigger. Accompanying the metal-ion...

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...

Highly cooperative double metalation took place when a novel ligand based on a bipyridine-phenol framework was allowed to react with nickel(II) acetate. The π-stacking of the square planar metal complex moieties is responsible for the highly cooperative double metalation judging from the X-ray crystal structure in which two complex moieties stack on top of each other in a parallel fashion.

In this report we present a study of a series of Re(CO)3 pyridine-imine complexes with pendant phenol groups. We investigated the effects of the position of the phenol hydroxyl group (para, meta or ortho to the imine) on the steric and electronic characteristics of a series of Re(CO)3X(pyca-C6H4OH) compounds, where X = Cl, Br and pyca = pyridine-2-carbaldehyde imine. These compounds can be gene...

The activity of dibenzylzirconium and dibenzylhafnium Salalen complexes in polymerisation of propylene with MAO as a cocatalyst is described. Three Salalen ligand precursors combining a bulky alkyl group (1-adamantyl) on the imine-side phenol and electron withdrawing halo groups of different sizes on the amine-side phenol were explored. All metal complexes were obtained as single diastereomers....

Copper ions in the active sites of several proteins/enzymes interact with phenols and quinones, and this interaction is associated to the reactivity of the enzymes. In this study the speciation of the Cu(2+) with iminodiacetic phenolate/hydroquinonate ligands has been examined by pH-potentiometry. The results reveal that the iminodiacetic phenol ligand forms mononuclear complexes with Cu(2+) at...
