The complexes have been characterized on the basis of elemental analyses, molar conductance, magnetic susceptibility measurements and electronic spectral studies. Sharp bands were observed in the electronic spectra of the complexes. The 8 values could not be reported as the spectra and been recorded in Nujol mulls. The Ru(III) and Ir(III) complexes have been found to stabilize an octahedral geometry while a square-planar geometry is assigned to the Pd(II) and Pt(II) complexes.

In a patent, introducing its new discovery.

The photophysical processes have been investigated in first, second and third generation dendrimers with poly-(phenylenevinylene) branches and a ruthenium tris-bipyridine core, RuDn (n = 1-3). These dendrimers show very efficient forward singlet-singlet energy transfer from the branches to the ruthenium core upon UV irradiation, with efficiencies of 0.99 for RuD1 and 0.88 for RuD2 and RuD3 in CH2Cl2. The RuDn dendrimers show a bi-exponential emission decay in CH2Cl2, when excited with a 460 nm light with short lifetimes, however, the emission decay lifetimes become mono-exponential in 10% Triton X-100 aqueous solution (tau = 840 ns for RuD1, 890 ns for RuD2 and 1120 ns for RuD3).

The nitrosation of [Ru(NH3)6]2+ in hydrochloric acid and alkaline ammonia media has been studied; the patterns of interconversion of ruthenium complexes in reaction solutions have been proposed. In both cases, nitrogen(II) oxide acts as the nitrosation agent. The procedure for the synthesis of [Ru(NO)(NH3)5]Cl3 ? H2O (yield 75-80%), the main nitrosation product of [Ru(NH 3)6]2+, has been optimized. Thermolysis of [Ru(NO)(NH3)5]Cl3 ? H2O in a helium atmosphere has been studied; the intermediates have been identified. One of these products is polyamidodichloronitrosoruthenium(II) whose subsequent decomposition gives an equimolar mixture of ruthenium metal and dioxide. The structure of trans-[RuNO(NH3)4Cl]Cl2, formed in the second stage of thermolysis and as a by-product in the nitrosation of [Ru(NH3)6]Cl2, has been determined by X-ray diffraction.

Reaction of the readily available metal acetylide complexes Ru(CCC 6H4R-4)(PPh3)2Cp (R = OMe, Me, H, CN, CO2Me), Ru(CCFc)(PPh3)2Cp and Fe(CCC 6H4R-4)(dppe)Cp (R = Me, H) with 1-cyano-4- dimethylaminopyridinium tetrafluoroborate affords cyanovinylidene complexes [Ru{CC(CN)C6H4R-4}(PPh3)2Cp]BF 4, [Ru{CC(CN)Fc}(PPh3)2Cp]BF4 and [Fe{CC(CN)C6H4R-4}(dppe)Cp]BF4 in an experimentally simple fashion. These synthetic studies are augmented by refinements to the preparation of the key iron reagents FeCl(dppe)Cp and Fe(CCC6H4R-4)(dppe)Cp. Molecular structure determinations, electrochemical measurements, representative IR spectroelectrochemical studies and DFT studies have been used to provide insight into the electronic structure of the cyanovinylidene ligand, and demonstrate that despite the presence of the cyano-substituted methylidene fragment, reduction takes place on the vinylidene Calpha carbon.

In a patent, introducing its new discovery.

A new series of panchromatic ruthenium(II) sensitizers derived from carboxylated terpyridyl complexes of tris-thiocyanato Ru(II) have been developed. Black dye containing different degrees of protonation {(C2H5)3NH}[Ru(H3tcterpy)(NCS) 3] 1, {(C4H9)4N}2[Ru(H2 tcterpy)(NCS)3] 2, {(C4H9)4N}3[Ru(Htcterpy)(NCS) 3] 3, and {(C4H9)4N}4[Ru(tcterpy)(NCS) 3] 4 (tcterpy = 4,4?,4?-tricarboxy-2,2?:6?,2?-terpyridine) have been synthesized and fully characterized by UV-vis, emission. IR, Raman, NMR, cyclic voltammetry, and X-ray diffraction studies. The crystal structure of complex 2 confirms the presence of a RuIIN6 central core derived from the terpyridine ligand and three N-bonded thiocyanates. Intermolecular H-bonding between carboxylates on neighboring terpyridines gives rise to 2-D H-bonded arrays. The absorption and emission maxima of the black dye show a bathochromic shift with decreasing pH and exhibit pH-dependent excited-state lifetimes. The red-shift of the emission maxima is due to better pi-acceptor properties of the acid form that lowers the energy of the CT excited state. The low-energy metal-to-ligand charge-transfer absorption band showed marked solvatochromism due to the presence of thiocyanate ligands. The Ru(II)/(III) oxidation potential of the black dye and the ligand-based reduction potential shifted cathodically with decreasing number of protons and showed more reversible character. The adsorption of complex 3 from methoxyacetonitrile solution onto transparent TiO2 films was interpreted by a Langmuir isotherm yielding an adsorption equilibrium constant, Kads, of (1.0 ± 0.3) × 105 M-1. The amount of dye adsorbed at monolayer saturation was (na = 6.9 ± 0.3) × 10-8 mol/mg of TiO2, which is around 30% less than that of the cis-di(thiocyanato)bis(2,2?-bipyridyl-4,4?-dicarboxylate) ruthenium(II) complex. The black dye, when anchored to nanocrystalline TiO2 films achieves very efficient sensitization over the whole visible range extending into the near-IR region up to 920 nm, yielding over 80% incident photon-to-current efficiencies (IPCE). Solar cells containing the black dye were subjected to analysis by a photovoltaic calibration laboratory (NREL, U.S.A.) to determine their solar-to-electric conversion efficiency under standard AM 1.5 sunlight. A short circuit photocurrent density obtained was 20.5 mA/cm2, and the open circuit voltage was 0.72 V corresponding to an overall conversion efficiency of 10.4%.

A mild, efficient and rapid domino reaction involving the Bestmann-Ohira reagent (BOR) and alpha,beta-unsaturated aldehydes has been developed for the synthesis of densely functionalized vinylpyrazoles. This reaction demonstrates the dual reactivity of BOR as a homologation reagent as well as a cycloaddition partner, thus constituting a domino reaction in an operationally simple procedure. The application of this efficient synthesis of pyrazoles has been demonstrated for the synthesis of phosphonyl analogues of pyrrolopyrazole alkaloids.

Tris(acetylacetonato<2-14C>)-cobalt(III), -chromium(III), -ruthenium(III), and -rhodium(III) undergo ligand exchange in acetylacetone(Hacac) at 85-190 deg C without decomposition of the complexes.The exchange rate is proportional to the complex concentration, and the first-order rate constant k0 decreases in the sequence Co(III) above Cr(III) above Ru(III) above Rh(III), k0/10-5 s-1 being 2.4 (93 deg C), 5.6 (117 deg C), 9.5 (158 deg C), and 2.4 (185 deg C), respectively.The activation enthalpies and entropies and deuterium isotope effect on k0 are significantly different between the Co(III) and the Cr(III), Ru(III) and Rh(III) complexes.An intermediate involving an one-ended acetylacetonate and a solvent molecule(Hacac) is concluded to be formed in the rate-determining step.The SN1 and the SN2 mechanism are assigned to the exchange reactions of the Co(III) complex and the others, respectively, for the rate-determining steps.

Synthesis of novel pyrazole-fused heterocycles, i.e., dihydro-1H- or 2H-oxepino[3,2-c] pyrazoles (6 or 7) from 4-allyloxy-1H-pyrazoles (1) via combination of Claisen rearrangement and ring-closing metathesis (RCM) has been achieved. A suitable catalyst for the RCM of 5-allyl- 4-allyloxy-1H-pyrazoles (4) was proved to be the Grubbs second generation catalyst (Grubbs2nd) to give the predicted RCM product at room temperature in three hours. The same reactions of the regioisomer, 3-allyl-4-allyloxy-1H-pyrazoles (5), also proceeded to give the corresponding RCM products. On the other hand, microwave aided RCM at 140 C on both of 4 and 5 afforded mixtures of isomeric products with double bond rearrangement from normal RCM products in spite of remarkable reduction of the reaction time to 10 min.
