New phosphoramidite complexes of ruthenium chiral at the metal were synthesized, structurally characterized and their electrochemical and catalytic properties were studied. Reaction of the known chiral phosphoramidites (RO)2 PNR2? (R = naphthyl, R? = CH3, 1a; R = naphthyl, R? = benzyl, 1b; R = octahydronaphthyl, R? = benzyl, 1c) with CpRu(PPh3)2Cl afforded the title compounds CpRu(PPh3)(1a-c)(Cl) (2a-c) in 46-74% isolated yields. Fractional crystallization of 2b and 2c afforded the corresponding diastereopure complexes which are chiral both at the metal and at the ligand. The molecular structures of 2b and 2c were determined, revealing a pseudo octahedral coordination geometry about the ruthenium center. Electrochemical studies by cyclic voltammetry showed reversible electrochemical behavior of the metal complexes 2a-c. The new metal complexes are catalytically active in the Mukaiyama aldol reaction (24 h, room temperature, 31-53% yield), but almost no enantiomeric excesses for the products were obtained.

Synthesis and characterization of two ruthenium(II) and osmium(II) complexes (1 and 2) having carbohydrate derived salen ligand and in situ ligand reduction are reported. The1,2-O-isopropylidene-3,5-diazido-3,5-dideoxy-alpha- d-xylopyranoside (L1) was reduced by catalytic hydrogenation using continuous flow hydrogen reactor in the presence of salicylaldehyde to form the corresponding bis-imino derivative H2L2. The ligand H2L2 has been transformed to H2L3 upon reduction of one of the imine bonds in consequence to the oxidation of the leaving PPh3 group to POPh3. Systematic spectroscopic characterization, 1H and 13C NMR, mass spectrometry, electronic spectra reveals the composition of the complexes. X-ray crystal structures of both the complexes are reported. Detailed electrochemical studies reveal the redox behaviour of the complexes and DFT calculations help to get the idea about the intense lowest-energy absorption for these two complexes.

Reaction of benzaldehyde semicarbazone (HL-R, where H is a dissociable proton and R is a substituent (R = OMe, Me, H, Cl, NO2) at the para position of the phenyl ring) with [Ru(PPh3)3Cl2] and [Ru(PPh3)2(CO)2Cl2] has afforded complexes of different types. When HL-NO2 and [Ru(PPh3)3Cl2] react in solution at ambient temperature, trans-[Ru(PPh3)2(L-NO2)Cl] is obtained. Its structure determination by X-ray crystallography shows that L-NO2 is coordinated as a tridentate C,N,O-donor ligand. When reaction between HL-NO2 and [Ru(PPh3)3Cl2] is carried out in refluxing ethanol, a more stable cis isomer of [Ru(PPh3)2(L-NO2)Cl] is obtained. The trans isomer can be converted to the cis isomer simply by providing appropriate thermal energy. Slow reaction of HL-R with [Ru- (PPh3)2(CO)2Cl2] in solution at ambient temperature yields 5-[Ru(PPh3)2(L-R)(CO)Cl] complexes. A structure determination of 5-[Ru(PPh3)2(L-NO2)(CO)Cl] shows that the semicarbazone ligand is coordinated as a bidentate N,O-donor, forming a five-membered chelate ring. When reaction between HL-R and [Ru(PPh3)2(CO)2Cl2] is carried out in refluxing ethanol, the 4-[Ru(PPh3)2(L-R)(CO)Cl] complexes are obtained. A structure determination of 4-[Ru(PPh3)2(L-NO2)(CO)Cl] shows that a semicarbazone ligand is bound to ruthenium as a bidentate N,O- donor, forming a four-membered chelate ring. All the complexes are diamagnetic (low-spin d6, S = 0). The trans- and cis-[Ru(PPh3)2(L-NO2)Cl] complexes undergo chemical transformation in solution. The 5- and 4-[Ru(PPh3)2(L-R)(CO)Cl] complexes show sharp NMR signals and intense MLCT transitions in the visible region. Cyclic voltammetry of the 5-[Ru(PPh3)2(L-R)(CO)Cl] and 4-[Ru(PPh3)2(L-R)(CO)Cl] complexes show the Ru-(II)-Ru(III) oxidation to be within 0.66-1.07 V. This oxidation potential is found to linearly correlate with the Hammett constant of the substituent R.

The syntheses of the alkyne (E)-4,4?-HCCC6H4N=NC6H4NO 2 (1) and alkynyl complexes LnM{(E)-4,4?-CCC6H4N=NC6H 4NO2} [LnM=trans-[RuCl(dppm)2] (2), Ru(PPh3)2(eta-C5H5) (3), Au(PPh3) (4)] are reported. A structural study of 2 reveals E stereochemistry about the azo-linkage. Electrochemical data for the ruthenium complexes reveal that the azo-linkage in complexes 2 and 3 perturbs the metal-centred oxidation potential compared to all other alkynyl complexes of similar composition. Quadratic optical nonlinearities by hyper-Rayleigh scattering (HRS) at 1064 nm are very large for 2 and 3, but resonance-enhanced. Comparison of HRS data for 4 with those of Au{(E)-4,4?-CCC6H4X=CHC6H 4NO2}(PPh3) (X=CH, N) reveals that complex 4 has a significantly larger quadratic nonlinearity than its ene- or imino-linked analogues.

Acid-promoted hydrogen migration in (2-allylphenoxo)ruthenium(II) to form an eta3-allyl complex

Treatment of RuCP[OC6H4(CH2CH=CH 2)-kappa1O: eta2C,C?](PPh 3) (3c) with a Bronsted acid (HX) such as 2-al-lylphenol results in facile migration of a benzylic proton to the aryloxide, giving the (eta3-allyl)ruthenium(II) complex RuCp[CH2-CHCH(C 6H4OH-2)-eta3 C,C?,C?](PPh 3) (Ac). Thermodynamic and kinetic studies suggest that 3c associates with acid to give 3c · HX, and further addition of HX to 3c · HX causes the C-H bond cleavage reaction to give 4c.

Synthesis and structural characterization of some selenoruthenates and telluroruthenates

The reaction of solid [RuClCp(PPh3)2] with TeSe 32- or Sen2- in DMF leads to the formation of [RuCp(PPh3)(mu2-Se2)] 2 (1). In the structure of this compound the two bridging Se 2 groups lead to a six-membered Ru2Se4 ring in a chair conformation. Attached to each Ru center is a PPh3 ligand in an equatorial position and a Cp ring in an axial position. The compound is diamagnetic. The compound [Ru2Cp2(mu3-Se 2)(mu3-Se)]2 (2) is obtained under similar conditions in the presence of air. This structure comprises a centrosymmetric Ru4Se6 dimer formed from the two bridging Se groups and the two bridging Se2 groups. Each Ru center is pi-bonded to a Cp ring. The reaction of solid [RuClCp(PPh3)2] with a Te n2- polytelluride solution in DMF leads to the diamagnetic compound [(RuCp-(PPh3))2(mu2-(1,4-eta:3,6- eta)Te6)] (3). Here the Ru centers are bound to a bridging Te 6 chain at the 1, 4, 3, and 6 positions, leading to a bicyclic Ru2Te6 ring. Each Ru atom is bound to a Cp ring and a PPh3 group. This dimer possesses a center of symmetry. The structure of 3 is the first example of a bicyclic complex where fusion occurs along a Te-Te bond. If the same reaction is carried out in DMF/CH2Cl 2, rather than DMF, then [(RuCp(PPh3))2-(mu2- (1,4-eta:3,6-eta)Te6)]·CH2Cl2 (4) is obtained. In the solid state it possesses the same Ru2Te6 structural unit as does 3, but the unit lacks a crystallographically imposed center of symmetry. The electronic structures of 3 and 4 have been analyzed with the use of first principles density functional theory. Bond order analysis indicates that the Te-Te bond where fusion occurs has a shared bonding charge of about 2/3 of that found for Te-Te single bonds.
