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.
