Chlorocarbonyl ruthenium(II) complexes of tripodal triphos {MeC(CH2PPh2)3}: Synthesis, characterization and catalytic applications in transfer hydrogenation of carbonyl compounds

The complex [Ru(CO)2(triphos-κ2P)Cl2] (1) underwent decarbonylation in dichloromethane solution under air over a period of about two weeks to afford the chelated monocarbonyl complex [Ru(CO)(triphos-κ3P)Cl2] (2). The Single Crystal X-ray structure of 2 showed a slightly distorted metal centred complex. The catalytic activity of one of the complexes [Ru(CO)(triphos-κ3P)Cl2] (2) was examined in the transfer hydrogenation of aromatic carbonyl compounds and was found to be efficient with conversion up to 100% in the presence of isopropanol/NaOH.

Substituted ketene elimination from acid chlorides induced by ruthenium(0) compounds

The compound Ru(CO)2(triphos) (triphos=MeC(CH2PPh2)3) reacts with a number of acid chlorides RR'CHCOCl to form Cl and the corresponding substituted ketenes RR'CCO.A quantitative study of the reaction of Ph2CHCOCl shows that Ph2CCO is formed in a 1:1 stoichiometry.The compound Ru(CO)3(PPh3)2 also reacts with Ph2CHCOCl forming Ph2CCO and the unstable hydride Cl, the chemistry of which is also reported.

Oxidative addition reactions of dicarbonyl-[1,1,1-tris((diphenylphosphino)methyl)ethane]ruthenium(0). Elimination of ketene from an acetylmetal compound

Oxidative addition reactions of the title compound (Ru(CO)2(triphos)) with halogens, anhydrous hydrogen chloride, and several alkyl halides yield the series of complexes [RuX(CO)2(triphos)]+ (X = halide), [RuH(CO)2(triphos)]+, and [RuR(CO)2(triphos)]+ (R = Me, Et, PhCH2, allyl). Most of the compounds appear to exhibit normal chemical properties but the hydride is surprisingly acidic, possibly because the hydride ligand is forced into an unusual (for it) coordination position, trans to a phosphorus atom, which would lie high in the trans influence series. While oxidative addition of acetyl chloride appears to give the acetyl complex [Ru(COMe)(CO)2(triphos)]+, the latter is unstable and eliminates ketene to form the above-mentioned hydride complex. The unusual instability of the acetyl complex is perhaps also to be attributed in part to the high trans influence and pronounced trans bond weakening properties of tertiary phosphines.
