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

摘要

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.
