"Non-Innocent Ligands in Bioinorganic Chemistry - An Overview"


WOLFGANG KAIM
Institut fuer Anorganische Chemie
Universitaet Stuttgart, Alemania


Resumen:

The presentation describes the most common instances where non-innocent
("suspect") behaviour of redox-active ligands is observed in a biochemical
context. Both substrates and supporting components are covered, ranging
from dioxygen (O2, superoxide, peroxide) via NO (cation, neutral radical,
anion) to quinone, phenol, porphyrin, pterin, flavin and dithiolene
systems. These non-innocent ligands display their function in the
interaction with Fe, Cu, Mn, Mo or W centers.
