By grafting 4,5-diazofluorene-9-one (DAFO) onto mesoporous silica and forming a Pd(II)-complex, a catalyst capable of selective oxidation of cyclohexene to cyclohexanone was obtained. The catalyst showed good catalytic activity and stability, inhibiting the formation of Pd-black during the reaction.
The grafting of 4, 5-diazofluorene-9-one (DAFO) to the mesoporous silica functionalized with aminopropyltriethoxysilane resulted in a material capable of absorbing Pd(II) to form a Pd(II)-complex through coordination reaction. Characterization of the loaded Pd(II)-complex by FT-IR, ICP and XPS discloses the structure of the complex, the content and chemical state of palladium. The novel Pd(II)-complex was tested for selective oxidation of cyclohexene to cyclohexanone by H2O2. The stability of the catalyst and the heterogeneity of the reaction were proved by catalyst recycling test and hot-filtration test, and the oxidative reaction was catalyzed predominantly by the loaded Pd(II)-complex. No any Pd-black was found during the whole reaction process, indicating that the complex can effectively promote the redox cycle of the active component palladium and inhibit the formation of Pd-black.
