The formylation of 3-methoxypropylamine with hydrogen and supercritical carbon dioxide over Ru-based catalysts was studied. In this solventless process, carbon dioxide acts as both reactant and solvent. Interestingly, Ru/Al2O3 modified by the phosphine 1,2-bis(diphenylphosphino)ethane (dppe) showed a high formylation activity at 100% selectivity, comparable to those of the homogeneous catalysts RuCl 2(dppe)2 and RuCl2(PPh3) 3. Analysis of the reaction mixture by ICP-OES and structural studies by in situ X-ray absorption spectroscopy discovered that the presence of the phosphine modifier led to the formation of a homogeneous ruthenium catalyst.

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.
