The complex [CpRu(eta6-naphthalene)]PF6 (2) is a readily accessible and air-stable source of the CpRu+ fragment (Cp = eta5C5H5) for applications in complex synthesis and catalysis. The utility of this precursor complex is demonstrated in a number of experiments: The counterion of 2 is exchanged by reaction with cinchonidinium A-TRISPHAT to give [CpRu(eta6-naphthalene)]A- TRISPHAT (4; with X-ray crystal structure). Ligand exchange of 2 in acetonitrile with (Z,Z)- 1,5-cyclooctadiene (COD) produces [CpRu(eta2: eta2-COD)(MeCN)]PF6 (5; with X-ray crystal structure); with chelating phosphanes (P-P), complexes [CpRu(P-P)(MeCN)]PF6 are selectively generated, and starting with a 1,4-diazadiene, a solvento complex [CpRu(diazadiene-N,N?)(MeCN)]PF6 is obtained. Stepwise reaction of 2 (or 4) in acetonitrile with different monodentate phosphanes PR3 and PR’3 first gives [CpRu(PR 3)(MeCN)2]+ (I), then the chiral-at-metal cation [CpRu(PR3)(PR’3)(MeCN)]+ (II), which was resolved spectroscopically (31P NMR) when combined with the enantiopure Delta-TRISPHAT counterion. Complex cations of type I or II incorporating 2-diphenylphosphinopyridines as ligands display either the eta1-p or the chelating eta2-P,N coordination mode, depending on the size of the ligand and, in solution, the solvent. Reaction of 2 with 3 equiv of triarylphosphanes (PR3) in hot acetone gives rise to [CpRu(PR3)3]+, including the previously unknown cation [CpRu(PPh3)3]+. The in situ combination of 2 and 2 equiv of bulky 6-substituted 2-pyridylphosphanes catalyzes the anti-Markovnikov hydration of terminal alkynes to aldehydes. Either complex 2 or 5 catalyzes the [2+2+2]-cycloaddition of COD with alkynes. Complex 5 is a catalyst for the coupling of allyl alcohols with terminal alkynes to give 4-alkenones.

Carbonyl-containing Ru and Fe heterobimetallic complexes were prepared and tested as electrocatalysts for the oxidation of methanol and ethanol. GC analysis of the electrolyte solution during bulk electrolysis indicated that CpRu(CO) (mu-I) (mu-dppm) PtI2 (1), CpFe(CO) (mu-I) (mu-dppm) -PtI2 (2), and CpRu(CO) (mu-I) (mu-dppm) PdI2 (3) were catalysts for the electrooxidation of methanol and ethanol, while CpFe(CO) (mu-I) (mu-dppm) -PdI2 (4), CpRu(CO) I(mu-dppm) AuI (5), and CpFe(CO) I(mu-dppm) AuI (6) did not function as catalysts. The oxidation of methanol resulted in two-and four-electron oxidation to formaldehyde and formic acid, respectively, followed by condensation with unreacted methanol to yield dimethoxymethane and methyl formate as the observed products. The oxidation of ethanol afforded 1, 1 – diethoxyethane as a result of two-electron oxidation to acetaldehyde and condensation with excess ethanol. FTIR analysis of the headspace gases during the electrochemical oxidation of methanol indicated formation of CO2. Isotopic labeling experiments demonstrated that the CO2 resulted from oxidation of the CO ligand instead of complete oxidation of CH3OH.

Reactions between HRuCl(PPh3)3 and 1,3- or 1,5-cyclooctadiene yield the 1,2-dihydropentalenyl complex (eta5-C8H9)Ru(PPh3) 2Cl through a series of steps including olefin insertion and electrocyclization. The reaction is accompanied by the loss of two equivalents of hydrogen. The product crystallizes in the monoclinic space group P1? (No. 2). (eta5-C8 H9)Ru(PPh3)2Cl catalyzes the dimerization of phenylacetylene to a ?2:1 mixture of Z: E 1,4-diphenyl-1-buten-3-yne. Comparison of the catalytic activity of (eta5-C8H9)Ru(PPh3) 2Cl with (eta5-C5H5) Ru(PPh3)2Cl, (eta5-C5 Me5)Ru(PPh3)H3 and {eta5 -HB(pz)3}Ru(PPh3)2Cl suggests that the more electron-rich eta5 ligands favor formation of the Z isomer.

The trimetallic complexes {Ru(PPh3)2Cp}2{mu-M(CN)4} and {Ru(dppe)Cp*}2{mu-M(CN)4} (M = Ni, Pd, Pt) have been prepared from reactions of RuCl(PPh3)2Cp or RuCl(dppe)Cp* with the appropriate tetracyanometallate salt, and structurally characterised. While a similar reaction of FeCl(dppe)Cp with K2[Pt(CN)4] afforded {Fe(dppe)Cp}2{mu-Pt(CN)4}, the iron cyanide complex Fe(CN)(dppe)Cp was isolated as the only iron containing product from reaction of FeCl(dppe)Cp with K2[Ni(CN)4]. The trimetallic complexes can be oxidised in two sequential one-electron steps. Spectroelectrochemical experiments reveal weak NIR absorption bands in the mono-oxidised complexes which are not present in the binuclear complex K[Ru(dppe)Cp*{Pt(CN)4}], and are therefore attributed to RuII ? RuIII charge transfer processes. The coupling parameter, Vab, extracted using Hush-style analysis falls in the range 250 ± 50 cm-1, consistent with the weak interaction between the Group 8 metal centres. The energy of the IVCT process is dominated by reorganisation energy of the Group 8 metal-ligand fragment.

Ruthenium allenylidene complexes with carbon-rich polyaromatic moieties have been synthesized by using [RuCl(eta5-C5H5)(PPh3)2] (eta5-C5H5 = cyclopentadienyl) as a precursor and the propargyl alcohols 10-ethynyl-10-hydroxyanthracen-9-one (ACO), 13-ethynyl-13-hydroxypentacen-6-one (PCO), 1-phenyl-1-(pyren-1-yl)prop-2-yn-1-ol (PyrPh), 9-ethynyl-9H-fluoren-9-ol (FN) and 6-ethynyl-6H-benzo[cd]pyren-6-ol (BPyr) as ligands. The resulting cationic allenylidene complexes, [Ru(eta5-C5H5)(CC(AO))(PPh3)2]PF6 (1), [Ru(eta5-C5H5)(CC(PCO))(PPh3)2]PF6 (2), [Ru(eta5-C5H5)(CC(PyrPh))(PPh3)2]PF6 (3), [Ru(eta5-C5H5)(CC(FN))(PPh3)2]PF6 (4), and [Ru(eta5-C5H5)(CC(BPyr))(PPh3)2]PF6 (5) show interesting intermolecular pi-interactions in the solid-state structure as well as solution state complexation with pyrene (documented by Job’s plots experiments). CV data indicate possible Ru(ii)/Ru(iii) oxidation, as well as the potential reduction of the carbon-rich allenylidene moiety.

Complexes of the formula [(N-N)Cu(AsPh3)CN] (N-N=2,2?-bipyridine, 1,10-phenanthroline) have been synthesized. Ru(bpy)2Cl2.2H2O and [(eta5-cp)Ru(PPh3)2Cl] react with [(N-N)Cu(AsPh3)CN] to give cyano-bridged compounds. IR spectral studies in the low frequency region (700-50 cm-1) and 4000-400 cm-1 region reveal cyano bridging in the complexes. Luminescence measurements suggest oxidation of metal centres (CuI-CuII and RuII-RuIII) on excitation at a charge transfer band. This has been substantiated with electrochemical studies of complexes which exhibit quasi-reversible reductions viz. RuIIIRuII and CuIICuI. The deposition of metallic copper is also observed at a potential of -1.55 V. Based on these data, a mechanism for photo-redox reaction of complexes has been presented. The properties of these bimetallic complexes are compared with those of parent complexes.
