Zusammenfassung:	Molybdenum and tungsten catalysts, PAF-30-Mo and PAF-30-W, synthesized based on a porous aromatic framework PAF-30 have been tested in the epoxidation of cyclohexene with tert- butyl hydroperoxide. The influence of the temperature and the substrate to oxidant ratio on the characteristic features of the process has been studied. It has been shown that the catalysts exhibit high activity and make it possible to obtain cyclohexene epoxide in a high yield; however, they lose their activity over time due to the leaching of the metal from the pores of the polymer.
