| abstract |
The present invention relates to a novel encapsulated organometallic cluster complex catalyst and to a process for the preparation thereof. The oxo-bridged organometallic cluster complex of the invention has at least one atom of cobalt and manganese encapsulated in micro and mesoporous porous solids like aluminosilicate zeolites, aluminophosphates, carbon molecular sieves, silica and is particularly effective for oxidation of aromatic alkyl groups to the carboxyl groups in high yields. |
