Rhodium nanoparticles (Rh NPs) stabilized by phosphine functionalized ionic liquids (FILs) were prepared in [BDMI]NTf 2 (BDMI=1-butyl-2,3-dimethylimidazolium, NTf 2 =bis(trifluoromethanesulfonyl)imide) using H 2 (g) (4bar) as a reducer. Rh(allyl) 3 was used as a “salt-free” Rh NP precursor and allowed to enhance the stability of the Rh NPs compared to the usual RhCl...
The organometallic synthesis of ruthenium nanoparticles stabilized by water-soluble alkyl sulfonated diphosphines as ligands is described for the first time. After isolation, the so-obtained nanoparticles could be easily dispersed into water giving rise to stable aqueous colloidal solutions without precipitation over the course of several months. The catalytic behaviour of these aqueous colloidal...
