Abstract
Active solid oxidation catalysts can be obtained by incorporating dioxomolybdenum(VI) species derived from MoO2Cl 2(OPMePh2)2 into silica matrices via a sol-gel method. The supported catalyst has been characterized by elemental analysis, XRD, N2-physisorption, FT-IR, FT-Raman, UV-vis and solid-state MAS NMR spectroscopy, and a pathway for the reaction between MoO2Cl 2(OPMePh2)2 and tetraethoxysilane (TEOS) is suggested. The molybdenum catalyst was tested in the epoxidation of cyclohexene in the presence of tert-butyl hydroperoxide (TBHP). The conversion of cyclohexene and the selectivity to the epoxide were very high and increased further on raising the reaction temperature. © 2005 Elsevier B.V. All rights reserved.
