Abstract: Transition metal complexes bonded to silica via silanes with β-diketonate groups can be used as packings for complexation gas chromatography or as immobilized homogenous metal complex
catalysts. On basis of elemental analysis and the determination of surface area, possible structures of the complexes formed
on the silica surface have been proposed. The possibility of using the immobilized complexes as catalysts has been indicated.
Especially nickel complexes were taken into consideration. These immobilized complexes were used previously as packings for
complexation gas chromatography.
Keywords: supported metal complexes -
β-diketonate complexes - hydrosilylation
