Recently, Dupont and coworkers described the use of room-temperature imi-dazolium ionic liquids for the formation and stabilization of transition-metal nanoparticles. The potential interest in the use of ionic liquids is to promote a bi-phasic organic-organic catalytic system for a recycling process. The mixture forms a two-phase system consisting of a lower phase which contains the nanocatalyst in the ionic liquid, and an upper phase which contains the organic products. Rhodium and iridium [105], platinum [73] or ruthenium [74] nanoparticles were prepared from various salts or organometallic precursors in dry 1-bu-tyl-3-methylimidazolium hexafluorophosphate (BMI PF6) ionic liquid under hydrogen pressure (4 bar) at 75 °C. Nanoparticles with a mean diameter of 2-3 nm...

The dimeric ruthenium(I) and osmium(I) salts [M2(CNXylyl),0](PF6)2 have been isolated respectively from the melt of [( /, tf2-CgH,3)-Ru(CNXylyl)4]PF6 and from single-electron oxidations on Os(CNXylyl)5 with tropylium hexafluorophosphate (36). A brief mention of the formation of the salt [Ru2(L2)4](PF6)2 (L2 = 2,5-dimethyI-2,5-diisocyanohexane) has appeared (37). 

Ruthenium has been fixed to porphyrins also in an exocyclic , peripheral manner. 5-(4-Pyridyl)-10,15,20-tri(p-tolyl)porhyrin was treated with [Ru(NH3)5-OH2] [PF6]2 at room temperature in acetone for 4 h under conditions which are far too mild for ruthenium insertion to the porphyrin hole. A pentam-mineruthenium (III) fragment was thus attached to the pyridyl ring yielding a trication which seems to have been isolated as the hexafluorophosphate ... 

Bernhard and coworkers [58] have addressed the discovery of ionic iridium(III) and ruthenium(II) complexes by combinatorial luminophore synthesis and screening (Scheme 5.9). Starting from iridium trichloride, cyclometalation with (hetero)arylpyridyl ligands 45 (Fig. 5.17) gives rise to the formation of binuclear iridium complexes 46. Upon complexation with bidentate N,N- or P,P-ligands 47 (Fig. 5.17), the cationic complex 48 is formed, which upon anion metathesis with hexafluorophosphate is transformed into the target complex 49. In this sequence, the step from 46 to 48 was performed in a traditional and a parallel manner, the latter leading to a library of 100 iridium and 10 ruthenium complexes. 

The interaction of an alkyne with (tj5-C5H5)(PR3)2RuX can result in the formation of a wide variety of ruthenium complexes. The nature of the products formed depends on the conditions used and the type of alkyne reacted. Reactions between I and terminal alkynes in the presence of ammonium hexafluorophosphate lead to the formation of cationic monosubstituted ruthenium vinylidene complexes in high yield, as shown for phenylacetylene in Eq. (61) (4,67,68).
