Abstract

Redox non-innocent ligands have been shown to facilitate chemical reactions by storing electrons on the scaffold, aiding in the generation of radicals and even furthermore, to interact with a substrate to carry out complex reactivity. Our group has focused efforts on the understanding of pyrazine(diimine) systems with first-row transition metals. In Chapter II will discuss the electronic structure of monoligated pyrazine(diimine) complexes with Ni and Co in two oxidation states. In Chapter III we will discuss the complex reactivity of a bispyrazine(diimine) cobalt complex towards electrochemical proton reduction with three different acids. In Chapter IV we will discuss the proton reduction studies with a pyrazine(diimine) nickel complex. Part of our work has been focused on understanding the differences in electronic structures and reactivity between pyrazine(diimine) and pyridine(diimine) complexes. Chapter IV will also cover the study of proton reduction with first-row pyridine(diimine) complexes.
