Homogeneous versus heterogeneous self-exchange electron transfer reactions of metal complexes: Insights from pressure effects

Article Abstract:

A linear log-log relationship should exist between the rate constants k(sub el) for heterogeneous electron transfer of transition-metal complexes at solid electrodes and k(sub ex) for the corresponding self-exchange reactions in homogeneous solution. Methods of measuring electrode reaction rates and the basic theoretical background are presented.

C2-symmetric chiral bis(oxazoline) ligands in asymmetric catalysis

Article Abstract:

A historic approach to asymmetric catalysis with chiral Lewis acid-box complexes (C2-symmetric bis(oxazolines)) is followed in a review that covers the literature from 1991 to the spring of 2005. It is concluded that box -based catalysts are not only efficient but are also clever molecular robots whose behavior can also be predicted.

Reversible coordinative bonds in molecular recognition

Article Abstract:

The use of reversible coordination to unsaturated transition metal complexes as receptor binding sites in molecular recognition is discussed. It is concluded that coordinatively unsaturated transition metal complexes are well established as binding sites for synthetic receptors.
