MoO2(acac)2 supported on multi-wall carbon nanotubes: Highly efficient and reusable catalysts for alkene epoxidation with tert-BuOOH

In the present work, the preparation, characterization and investigation of the catalytic activity of MoO2(acac)(2) supported on multi-wall carbon nanotubes modified with 2-aminopyridine and 1,2-diaminobenzene are reported. The catalysts were characterized by elemental analysis, FT-IR and UV-Vis spectroscopic techniques and scanning electron microscopy (SEM). The catalytic activity of molybdenyl acetylacetonate supported on multi-wall carbon nanotubes. MoO2(acac)@amine-MWCNTs, was investigated in the alkene epoxidation with tert-BuOOH. These heterogenized catalysts were successfully applied for efficient epoxidation of olefins with tert-BuOOH in 1,2-dichloroethane as the solvent. The prepared catalysts can be reused several times without significant loss of their catalytic activity. (C) 2012 Elsevier Ltd. All rights reserved.
