To study steric and electronic factors that affect the C-H activation of Schiff bases by the complex [Ru(PPh3)2(CO) 2Cl2], systematic spectroscopic analyses were performed for a family of Ru(II) complexes of type [Ru(PPh3)2(CO)L]. Among eight Schiff bases [H2Ln (n = 1-8)], synthesized by condensation of methyl-4-formyl benzoate with 4-aminoacetophenone, 1-naphthylamine, 2-amino-5-chloropyridine, 8-aminoquinoline, semicarbazide hydrochloride, 2-aminophenol, thiosemicarbazide and 2-aminothiophenol, it was observed that the C-H activation was dependent on the kind as well as the position of the coordinating atoms. The C-H activation of the Schiff bases was most facile in the formation of a Ru-CNO configuration followed by Ru-CNS, Ru-CNN, and Ru-CNC configurations, whereas for a Ru-NC(methine) configuration the activation was the slowest. X-ray crystal structures for five cycloruthenated complexes are reported. Detailed electrochemical studies reveals the redox behavior of the complexes and DFT calculations were performed to obtain geometry optimized structure of all other complexes and to get an insight of the electronic spectral behavior.

The coordination behavior and fluorescence spectra of pyrene-appended Schiff bases and the ruthenium(II) complexes were studied. The study was done with two generic types of ruthenium(II) precursor with different set of Lewis base ligands. The Lewis base ligands chosen were (i) 2,2?-bipyridine and (ii) triphenyl phosphine and carbonyl together. The molecular structures of two of the complexes were studied by X-ray crystallography. The effect of these two different set of ligands as well as the Schiff base ligands on the fluorescence spectra of the complexes in organic solvent were compared.

A general synthetic approach based on the hydrolysis of R?3Si-NR2 with organic compounds containing acidic protons, to construct thin films of donor ligands on inorganic oxide surfaces that are subsequently used to support a variety of organometallic complexes, is reported. The reaction of surface hydroxyl groups on silica, glass, quartz, and single-crystal silicon with SiCl4, followed by NEt2H, affords surface-anchored Si-NEt2 moieties which, upon simple acid-base hydrolysis with HO-(CH2)n-XR2 (n = 3, X = N, R = C2H5; n = 3, X = P, R = C6H5; n = 4, X = P, R = C2H5), HO-C6H4-XR2 (X = P, R = C6H5; X = N, R = C2H5), and HO-CH(CH3)-(CH2)3-N(C2H 5)2 at ambient temperature, yield thin films containing terminal phosphine and amine donor ligands. These ligands are then used to covalently anchor organometallic complexes of Ni(0), Rh(I), Ru(II), and Pd(0) via bridge-splitting or ligand-displacement reactions. The synthesis of solution models to the surface-bound species and the characterization of the latter using numerous surface analytical techniques have proven useful in determining the conditions for the deposition process and in the evaluation of the structure of the supported metal complexes. A thin film of [Si]-O-(CH2)3PPh2Ni-(CO)2PPh 3 on glass catalyzes the oligomerization of phenylacetylene resulting in a product distribution different from that of a similar reaction in solution. The enhanced activity and selectivity of the organometallic Ni(0) thin films suggests that a positive role is played by the orientation of the surface-bound organometallic species in catalysis.

The “weak-link approach” for the synthesis of metallomacrocycles has been used to synthesize a series of novel Ru(II) macrocycles in high yield. RuCl2(PPh3)3 has been reacted with two different phosphino-alkyl-ether hemilabile ligands, 1,4-(PPh2(CH 2)2O)2C6H4 and 1,4-(PPh2(CH2)2OCH2) 2C6H4. The hemilabile bidentate ligand coordinates to Ru(II) centers through both the P and O atoms to form bimetallic “condensed intermediates”. The weak Ru-O bonds have been selectively cleaved with CO, 1,2-diaminopropane, and pyridine to yield large open macrocycles. This is the first example of the weak-link approach employed to synthesize macrocycles with Ru, and metal centers in general that have more than four coordination sites.

Upon reaction with [Ru(PPh3)2(CO)2Cl2], N-(naphthyl)-4-R-salicylaldimines (R = OCH3, H, Cl; H2L1-H2L3) and 2-hydroxy-N-(naphthyl)naphthaldimine (H2L4) readily undergo cycloruthenation by C-H bond activation at the peri position to afford complexes of the type [Ru(PPh3)2(L)(CO)] (L = L1-L4). The crystal structures of the [Ru(PPh3)2(L)(CO)] (L = L1, L2, L4) complexes were determined and the structure of [Ru(PPh3)2(L3)(CO)] optimized by DFT calculations. The thermodynamics for the reaction of [Ru(PPh3)2(CO)2Cl2] with H2L2 to give [Ru(PPh3)2(L2)(CO)] were determined. All the complexes show intense absorptions in the visible and UV regions, which have been analyzed by TDDFT calculations. Cyclic voltammetry of the four cycloruthenated complexes showed two oxidations within the range 0.50-1.35 V versus SCE and a reduction at around -1.75 V versus SCE. The [Ru(PPh3)2(L)(CO)] (L = L1-L4) complexes were found to efficiently catalyze the transfer hydrogenation of carbonyl compounds.

A method for isomerizing a maleate, or a maleate containing a 2-propenyloxy group in the molecule at a high selectivity is provided which employs an isomerizing catalyst containing a Group VIII element. This method produces a fumarate, or a fumarate containing a 1-propenyloxy group in a high yield, which is useful in the fields of resin source materials and plasticizer. This method gives high-purity fumarates containing no catalyst residue by use of a heterogeneous catalyst which is readily separable and non-corrosive.

Reaction of benzaldehyde thiosemicarbazones [H2LR, where H 2 stands for the two protons, the hydrazinic proton, and the phenyl proton at the ortho position, with respect to the imine function and R (R = OCH3, CH3, H, Cl, and NO2) for the para substituent] with [Ru(PPh3)2(CO)2Cl 2], carried out in refluxing ethanol, afforded monomeric complexes of type [Ru(PPh3)2(CO)(HLR)(H)]. The crystal structure of the [Ru(PPh3)2(CO)(HLNO2)(H)] complex was determined. The thiosemicarbazone ligand is coordinated to the ruthenium center as a bidentate N,S-donor ligand forming a four-membered chelate ring. When the reaction of the thiosemicarbazones with [Ru(PPh3)2(CO) 2Cl2] was carried out in refluxing toluene, a family of dimeric complexes of type [Ru2(PPh3) 2(CO) 2(LR)2] were obtained. The crystal structure of [Ru 2(PPh3)2(CO)2(LCl)2] was determined. Each thiosemicarbazone ligand is coordinated to one ruthenium atom, by dissociation of the two protons, as a dianionic tridentate C,N,S-donor ligand, and at the same time the sulfur atom is also bonded to the second ruthenium center. 1H NMR spectra of the complexes of both types are in excellent agreement with their compositions. All the dimeric and monomeric complexes are diamagnetic (low-spin d6, S = 0) and show intense absorptions in the visible and ultraviolet regions. Cyclic voltammetry of the [Ru(PPh3)2(CO)(HLR)(H)] and [Ru2(PPh 3)2-(CO)2(LR)2] complexes show the ruthenium(II)-ruthenium(III) oxidation within 0.48-0.73 V vs. SCE followed by a ruthenium(III)-ruthenium(IV) oxidation within 1.09-1.47 V vs. SCE. Potentials of both the oxidations are found to correlate linearly with the electron-withdrawing character of the substituent R. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
