The invention relates to a catalyst system based on a polymer compound comprising at least one silasosquioxane-metal complex for the oxidation and oximation of organic compounds using peroxides, to a process for its preparation and to the use of these catalyst systems. Silasesquioxane compounds and metal complexes of these compounds are known. These compounds can be used as catalysts. If the compounds are used as catalysts, a frequently encountered difficulty is that the catalyst cannot be reused and is also difficult to separate from the product of the catalytic reaction. These problems can be avoided by the use of the polymer compounds of the invention which comprise at least one silasesquioxane-metal complex and have a molecular weight Mn of greater than 1 000 g/mol. These catalyst syste ms of the invention can be used both as homogeneous catalysts and as heterogeneous catalysts. In particular, the catalysts of the invention can used for catalyzing oxidation or oximation reactions.
