Molybdenum hexacarbonyl supported on amine modified multi-wall carbon nanotubes: an efficient and highly reusable catalyst for epoxidation of alkenes with tert-butylhydroperoxide

Abstract

In the present work, highly efficient epoxidation of alkenes catalyzed by Mo(CO)(6) supported on multi-wall carbon nanotubes modified by 2-aminopyrazine, APyz-MWCNTs, is reported. The prepared catalyst was characterized by elemental analysis, scanning electron microscopy, FT IR and diffuses reflectance UV-vis spectroscopic methods. This new heterogenized catalysts, [Mo(CO)(6)@APyz-MWCNT], was used as a highly efficient catalyst for epoxidation of alkenes with tert-BuOOH. This robust catalyst was reused several times without loss of its catalytic activity. Copyright (C) 2010 John Wiley & Sons, Ltd.
