Ruthenium hydride complex supported on multi-wall carbon nanotubes for catalytic C-C bond formation via transfer hydrogenation

Abstract

In this work, the preparation, characterization and investigation of catalytic activity ruthenium hydride catalyst, [RuHCl(CO)(PPh3) 3], supported on MWCNT in the synthesis of β,γ-unsaturated ketones via carbon-carbon bond formation are reported. In the first reaction step, the MWCNTs were modified with 1,2-ethanedithiol, and in a second reaction step, the catalyst was attached to MWCNTs via this linker. The catalyst was characterized by diffuse reflectance UV-vis and FT-IR spectroscopic techniques, SEM, ICP and elemental analysis methods. The catalyst was reused several times without significant loss of its catalytic activity. © 2012 Elsevier B.V. All rights reserved.
