Heterolytic H2 Activation by Dihydrogen Complexes. Effects of the Ligand X in [M(X)H2{Ph2P(CH2)3PPh 2}2]n+ (M = Ru, Os; X = CO, Cl, H)

Complexes of the general formula [MXH2(dppp)2]n+ (M = Ru, Os; X = H, Cl, CO; dppp = 1,3-bis-(diphenylphosphino)propane) have been prepared and characterized, and the effect of the donor/acceptor properties of X on their structure and acidity has been studied. The five-coordinate complexes [MCl(dppp)2]+ (M = Ru (1a), Os (1b)) react with H2 gas in CH2Cl2 to give the complexes [MCl(η2-H2)(dPPP)2]+ (M = Ru (2a), Os (2b)) containing elongated dihydrogen ligands. The molecular structure, of 2b has been determined by X-ray crystallography (monoclinic, space group P21/n with a = 13.314(7) A?, b = 18.63(2) A?, c = 23.20(2) A? β = 94.58(6)° and Z = 4). Chlorohydride [OsH(Cl)(dppp)2] (3b) reacts with H2 gas in the presence of Na[BPh4] forming [OsH3(dppp)2]+ (4b). Protonation of [OsH2(dPpp)2] (5b) with HBF4·Et2O also gives 4b. A combination of X-ray crystallography (monoclinic, space group P21/n with a = 13.392(3) A?, b = 25.306(7) A?, c = 21.247(7) A?, β = 91.15(2)° and Z = 4) and 1H and 31P NMR studies indicate that 4b is a classical trihydride. Hydridocarbonyls [MH(CO)(dppp)2]+ (M = Ru (6a), Os (6b)) are protonated by F3CSO3H in CD2Cl2 to yield [M(CO)(η2-H2)(dPpp)2]2+ (M = Ru (7a), Os (7b)), which were characterized in solution. 7a is stable only at low temperature. Compound 7b is a highly acidic dihydrogen complex with an estimated PKa of -6.

Ruthenium (II) - catalyzed oxidation of alcohols by persulfate

Alcohols are oxidized to carbonylic compounds by aqueous persulfate in the presence of catalytic amounts (0.2%) of ruthenium trichloride and of a choice of ruthenium (II) complexes. Secondary alcohols are quantitatively converted to ketones, whereas primary alcohols can be converted to aldehydes with good selectivities. A kinetic investigation suggests a concerted mechanism for the bi-electronic oxygen transfer.

Oxidative cleavage of styrene with oxygen catalysed by phosphinoruthenium(II) complexes

Highly selective oxidative cleavage of styrene by dioxygen has been achieved in mild conditions and in the presence of catalytic amounts of ClO4 or trans- (DPP=1,3-bis(diphenylphosphino)propane).
