Significance
An aqueous solution of IL-f-MWCNTs 1 and Na2PdCl4 was hydrogenated under 1 atm of H2 pressure for 30 min at room temperature to give Pd/IL-f-MWCNTs 2a (eq. 1). Direct anion exchange of the hydrophilic Br anion with NTf2 and SbF6 afforded the hydrophobic Pd/IL-f-MWCNTs 2b and 2c, respectively (eq. 2). The catalytic activities of 2a-c were examined for the hydrogenation of trans-stilbene in MeOH. Pd/IL-f-MWCNT 2c with the SbF6 anion showed superior catalytic activity compared to 2a and 2b (eq. 3).
