Redox reactivity coordinated ligands

Redox Reactivity of Coordinated Ligands in Pentacyano(L)Ferrate Complexes Jose A. Olabe... 

Organic ligands without redox reactivity that coordinate metal oxide surface sites have been found to enhance rates of both reductive and non-reductive dissolution reactions ( 7). ... 

REDOX REACTIVITY OF COORDINATED LIGANDS IN PENTACYANO(L)FERRATE COMPLEXES... 

The present volume is a non-thematic issue and includes seven contributions. The first chapter byAndreja Bakac presents a detailed account of the activation of dioxygen by transition metal complexes and the important role of atom transfer and free radical chemistry in aqueous solution. The second contribution comes from Jose Olabe, an expert in the field of pentacyanoferrate complexes, in which he describes the redox reactivity of coordinated ligands in such complexes. The third chapter deals with the activation of carbon dioxide and carbonato complexes as models for carbonic anhydrase, and comes from Anadi Dash and collaborators. This is followed by a contribution from Sasha Ryabov on the transition metal chemistry of glucose oxidase, horseradish peroxidase and related enzymes. In chapter five Alexandra Masarwa and Dan Meyerstein present a detailed report on the properties of transition metal complexes containing metal-carbon bonds in aqueous solution. Ivana Ivanovic and Katarina Andjelkovic describe the importance of hepta-coordination in complexes of 3d transition metals in the subsequent contribution. The final chapter by Sally Brooker and co-workers is devoted to the application of lanthanide complexes as luminescent biolabels, an exciting new area of development. 

In noncoordinating solvents (e.g. benzene) as a final product possessing TPP-ligands, the dimer [Rh"(TPP)]2 was found. In the presence of redox stable coordinating solvents (e.g. pyridine) the monomeric pentacoordinated Rh"(TPP) (py) was formed. In the presence of redox reactive solvents (e.g. CC14) the complex Rhn,(TPP)(CO)Cl was produced. The primary photochemical step is probably identical in all the systems. Its stoichiometry can be expressed as follows...
