Abstract

The invention relates to a method for producing silasesquioxane metal complexes of general formula (II) {RSiO1,5)n(RSiO1,5)m[(B)q(O)r]}u(M)v(Y)w, wherein R stands for C5-C10-cycloalkyl, norbornyl, adamantyl; R means oxygen; B stands for H, OH, halogen, alkoxy, SiRy, wherein R can be C1-C4 alkyl, aryl or substituted silyl groups and y stands for 2 and 3, and R and R can be functionalized; M stands for metals of the IV to VII PSE sub-group; Y stands for C1-C20 alkyl or aryl groups devoid of betahydrogen, silyl, alkoxy, OH, halogen, oxo, imido, fluorenyl, indenyl, cyclopentadienyl, whereby the individual ligands can be substituted; n = 6 and 7; m = 0 and 1; q = 0-2; r = 0-2; u = 1-4; v = 1-4; w = 0-12, wherein a metal compound of the IV to VII PSE sub-group and at least one silasesquioxane of general formula (I) {(RSiO1,5)n(RSiO1,5)m[(H)p(B)q(O)r]}, in which R, B, n, m, q, r have the above-mentioned meaning, and R stands for OH and p equals 0-4, are suspended in an akylated aromatic hydrocarbon, optionally in the presence of a basic compound by stirring at -80 to +110 DEG C and the reaction product is separated at room temperature. The invention also relates to metal complexes which comprise an oxidic metal cluster containing titanium atoms, wherein each titanium atom has been coordinated x 6. The invention also describes the use of said metal complexes as catalysts for the oxidation or epoxidation of unsaturated hydrocarbons or alcohols, also in an aqueous medium.
