Abstract
The preparation, characterization and investigation of catalytic activity of Mo(CO)(6) supported on multiwall carbon nanotubes modified with 4-aminopyridine is reported. The catalyst, [ Mo(CO)(5)-APy-MWCNT], was characterized by elemental analysis, scanning electron microscopy, and FT-IR and diffuse reflectance UV-vis spectroscopic methods. This new heterogenized catalyst was used as an efficient catalyst for alkene epoxidation with tert-butyl hydroperoxide (tert-BuOOH) in CCl(4) as solvent. This heterogeneous metal carbonyl catalyst showed high stability and reusability in the epoxidation reactions without loss of its catalytic activity. (C) 2010 Elsevier B.V. All rights reserved.
