MONO- AND BINUCLEAR IRON COMPLEXES IN ZEOLITES AND MESOPOROUS OXIDES AS BIOMIMETIC ALKANE OXIDATION CATALYSTS

摘要

The choice of the transition metal ion largely determines the spectroscopic properties and catalytic possibilities of the supramolecular systems. The coordinative stability of complexes of iron is very high. The higher oxidation states are more substitution inert than the lower ones. The catalytic implications of this choice are considerable, either two electron changes are seen as for oxo-chemistry with iron. One electron changes in radical or peroxo- chemistry are also seen for iron.
