چکیده
Zinc can be inserted into the carbahemiporphyrazines by use of the organometallic reagent diethylzinc; in the case of benziphthalocyanine, concomitant alkylation of an alpha-carbon position and metalation occurs.

Synthesis and Determination of Partition Coefficients of Zinc Complexes with Clinical Potential application
Zinc sulphate is currently used for treatment of zinc deficiency. Its uptake by the body is poor, necessitating the administration of high doses. This leads to a range of unpleasant side effects. In order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. Elemental analysis in eac...

متن کاملSpectrophotometric Study of Cobalt, Nickel, Copper, Zinc and Lead Complexes with Methylthymol Blue in Binary Water-Methanol Mixtures
The complexation reactions between methylthymol blue (MTB) and Co2+, Ni2+, Cu2+, Zn2+ and Pb2+ ions have been studied in different water-methanol mixtures at pH 4.45 and 25 °C by a spectrophotometric technique. The stepwise stability constants of the resulting 1:1 and 2:1 (metal ion to ligand) complexes were determined from the absorban...

متن کاملPreparation, Physicochemical Characterization and Biological Evaluation of Some Hesperidin Metal Complexes
AbstractThe ability of hesperidin (HP) to form complexes with five metals; cobalt, nickel, zinc, calcium and magnesium was investigated. The complexation was studied using U.V spectroscopic titration, in methanol as well as aqueous buffer solutions (physiological conditions). Potential complexes were studied by IR and NMR spectroscopy, melting point and their solubility were also evaluated. The...
