The interaction of bis(styrene)bis(triphenylphosphine)ruthenium, , with chelate ditertiary phosphines, Ph2P(CH2)nPPh2 , leads to ruthenium(0) complexes , which for P-P = dppm is extremely stable to heat, light, and the action of potential ligands. readily loses styrene and metallates a phenyl ring in toluene at room temperature or on heating and reacts with ligands L = CO or P(OMe)3 to give .With P(OMe)3 in refluxing n-octane, or with P(OPh)3, the hydride complex trans-(dppe)2> (R = Me or Ph) is produced.With Ph2P(CH2)3PPh2 (dppp), no ruthenium(0) complex can be isolated from reaction with , the main product being (dppp)>.The complexes have been characterised by microanalysis and by 1H and 31P n.m.r. spectra.

The formato ligand is readily introduced into the 5-coordinate complexes MRCl(CO)(PPh3)2 (M = Ru or Os, R = o-tolyl) giving 6-coordinate MR(η2-O2CH)(CO)(PPh3)2.In the presence of excess PPh3 thermal decarboxylation of the osmium complex leads to the stable aryl, hydride, OsRH(CO)(PPh3)3.A similar reaction with RuR(η2-O2CH)(CO)(PPh3)2 is accompanied by reductive elimination of RH and formation of Ru(CO)(PPh3)3 which as a solid is ortho-metallated, i.e. exists as .Decarboxylation and reductive elimination in the presence of bis(diphenylphosphino)ethane (dppe) give the zerovalent Ru(CO)(dppe)2. Ru(CO)(PPh3)3 undergoes a most unusual reaction with formaldehyde forming Ru(CH3)(η2-O2CH)(CO)(PPh3)2.
