Journal ArticleDOI

Coordination compounds of copper, nickel and iron with Schiff bases derived from hydroxynaphthaldehydes and salicylaldehydes

TL;DR: In this paper, a review describes Schiff bases of potential biological interest; for example, nickel compounds have been used in jack beam urease and in some hydrogenases, and the use of these compounds in catalytic reactions has also been considered.
Journal ArticleDOI

Complexes of macrocycles with pendant arms as models for biological molecules

TL;DR: In this paper, a review of inorganic models related to metalloenzymes which transport electrons or activate small molecules is presented, which are essentially restricted to macrocyclic or polydentate ligands preferentially containing nitrogen atoms and pendant arms.
Journal ArticleDOI

Carbon dioxide activation by aza-macrocyclic complexes

TL;DR: In this article, the production of fuels from the reduction of CO 2 catalyzed by coordination complexes of simple tetraaza-macrocyclilis, porphyrin, phthalocyanine and biphenanthrolinic hexaazacyclophanes is described.
Journal ArticleDOI

Ligand influence on the redox properties of some copper(II) complexes with schiff bases derived from bromosalicylaldehydes and methyl or chloro-substituted anilines

TL;DR: In this article, the synthesis, characterization and electrochemical behaviour of a new series of copper(II) complexes derived from substituted anilines and bromosalicylaldehydes have been studied.
Journal ArticleDOI

UV-visible spectroscopy in the interpretation of the tautomeric equilibrium of N,N′(bis-3,5-di-bromo-salicyliden)-1,2-diaminobenzene and the redox activity of its Co(II) complex. A quantum chemical approach.

TL;DR: In this article, the origin of the redox capability of N,N′(bis-3,5-di-bromo-salicyliden)-1,2-diaminobenzene Co (II) complexes, of major interest in the catalytic reduction of naphtas, is analyzed.
