Ruthenium -tertiary phosphine complex

Figure 1.22 Syntheses of tertiary phosphine complexes of ruthenium.

The water soluble tertiary phosphine complex of ruthenium(II), [RuCl2(PTA)4], (PTA=l,3,5-triaza-7-phosphaadamantane) was used as catalyst precursor for the hydrogenation of CO2 and bicarbonate in aqueous solution [51]. For this relatively... 

Ruthenium(O), d8 The chemistry is primarily one of mononuclear, polynuclear carbonyls and tertiary phosphine complexes a range of Ru° nitrosyls are known.

Many ruthenium complexes with nitrile ligands also feature tertiary phosphines, but simpler complexes can be synthesized [136]... 

A number of ruthenium(II) complexes have been prepared. Cole-Hamilton and Stephenson isolated cts-[Ru(Me2dtc)2L2] (L = PPhj, PMe2, Ph, PPhMe2, or P(OPh)3) from Ru(II) and Ru(III) tertiary phosphine and phosphite complexes with NaMe2dtc, and found that they undergo rearrangements (288). 

Amphiphilic resin supported ruthenium(II) complexes similar to those displayed in structure 1 were employed as recyclable catalysts for dimethylformamide production from supercritical C02 itself [96]. Tertiary phosphines were attached to crosslinked polystyrene-poly(ethyleneglycol) graft copolymers (PS-PEG resin) with amino groups to form an immobilized chelating phosphine. In this case recycling was not particularly effective as catalytic activity declined with each subsequent cycle, probably due to oxidation of the phosphines and metal leaching. 

Although the majority of ruthenium complexes contain tertiary phosphines as co-ligands, N-donor ligands are present in complexes obtained with Ru(tmeda) Cp [45], RuCl(Me2bpy)(PPh3)2 ]46], RuQ(L) [L = (dmpz)2-acetate [47], 2,6-(dmpz)2-...

A variety of 1,6-diyne substrates have been investigated for activity in the HSiR3/CO system. A ruthenium complex, Ru3(CO)12, with a tertiary phosphine additive catalyzes the formation of good yields of catechol products in which one molecule of diyne, two molecules of CO, and one or two molecules of silane are incorporated, as seen in Eq. (39).108... 

Phospholes can behave as simple two electron donors, in the same way as tertiary phosphines, and most of the transition metals have been complexed to phospholes. For example, ruthenium(II) forms a series of complexes [(Phole)2 Ru(CO)2C12] and [(Phole)3 Ru(CO)C12]. The formation of the tris phosphole complex attests to their small size. Because of the ring structure an unusual isomerism has been observed, with the rings either in the basal plane of the square pyramidal complex or normal to the basal plane (Figure 23). 

A large number of strapped arene complexes of ruthenium(ll) have been prepared by treatment of [RuCl2(il6-arene)]2 complexes with tertiary phosphines of the type R2P Ar in which an aromatic group is separated from the phosphorus atom by a two- or three-atom chain. In the first step, which usually occurs at or just above...
