corresponding to the nonequivalent phenyl groups at silicon. This is completely consistent with the structure of the corresponding modelcompound containing no bromine [ 25 ].

experiments were carried out to investigate whether the aromatics would be involved in this oxidation reaction. Taking toluene as modelcompound, the conversions of toluene oxidation at different temperatures are shown in Fig. 2 . The conversion of toluene
these complexes varies with the type of ligands, coordination sites and type of support in the heterogeneous catalysts.
Microporous and mesoporous materials that encapsulate metal complexes hold a key place as modelcompounds for mimicking
-based materials such as montmorillonite, zeolites and bentonite appear to be a fantastic method of heterogenization of homogeneous catalysts [ 23 – 25 ]. Nitrogen containing metal complexes such as N4-type Schiff base complexes are widely used as modelcompounds

flexible central spacer, were largely investigated for their interesting physical properties as well as the possibility to act as modelcompounds for semi-flexible main-chain liquid crystalline polymers [ 11 ].
