Here, we report a simple and useful strategy for a series of C3-symmetric pi-conjugated and highly soluble spiro-annulated truxene derivatives. The role of substituent at C5, C10, C15, C2, C7, and C12 positions was studied. We observed that truxenes containing carbonyl groups showed red shift in the absorption maxima in comparison with compounds devoid of carbonyl group. Enhanced conjugation in these systems may be responsible for this red shift. It was observed that truxene derivatives with carbonyl moiety exhibited faster decay than other derivatives. Benzyl groups play some role in the excited state dynamics as decay becomes slower when the spiro moiety was replaced by benzyl group at C5, C10, and C15 positions. Additionally, we noticed the highest quantum yield in t-butanol solvent and least in acetonitrile.

The synthesis of ruthenium complexes of cyclopentadienylidene phosphorane ligands C5H3R1-PR22R 3 (a: R1 = H, R2 = R3 = Ph; b: R1 = tBu, R2 = Ph, R3 = Me; c: R1 = H, R2 = R3 = nBu; d: R 1 = H, R2 = Ph; R3 = NHDip with Dip = 2,6-diisopropylphenyl) is described. The influence of steric and electronic effects of these ligands on spectroscopic and structural properties is analyzed by means of NMR spectroscopy and x-ray crystallography. Complexes of the form [Ru(eta5-C5H3R1-PR 22R3)(NCMe)3] [PF6] 23a-c are examined concerning their activity in a representative alkene-alkyne coupling reaction. The influence of the sterically demanding phosphonium ionic tag at the Cp-moiety on the yield and regioselectivity of the coupling of methyl 10-undecenoate with 1-octyne is investigated.

The performance of cross-metathesis reactions between acrylate esters and olefins catalyzed by Grubbs catalysts have been enhanced by the simple addition of p-cresol. For example, the efficiency of the cross metathesis reaction between methyl acrylate and 1-decene catalyzed by 2 was significantly increased by addition of p-cresol to the reaction mixture, resulting in increased product yields and E/Z ratios.

Pt and Pt-Ru alloys with several Pt/Ru ratios supported on carbon (Vulcan) were prepared using high-intensity ultrasound by reduction of H2PtCl6 and RuCl3 precursors in an aqueous solution. This method of catalyst preparation was performed in absence of any surfactant or organic addictive. The particles formed were characterized by X-ray diffraction (XRD), energy dispersive X-ray (EDX) and transmission electron microscopy (TEM). From the XRD studies, a decrease of metal particle size and of the lattice parameters was observed with the increase of the Ru content. The electroactivities were tested for the methanol oxidation reaction in acid electrolyte, and it was found that Pt-Ru catalysts were more activity than pure Pt.

The reaction of 2-guanidinobenzimidazole (GBI) and (eta5-C5H5)Ru(PPh3)2(Cl) in refluxing toluene gives the chelate [(eta5-C5H5)Ru(PPh3)(GBI)]+Cl- (1+Cl-; 96%). Subsequent anion metatheses yield the BF4-, PF6-, and BArf- (B(3,5-C6H3(CF3)2)4-) salts (77-85%). Reactions with CO give the carbonyl complexes [(eta5-C5H5)Ru(CO)(GBI)]+X- (2+X-; X- = Cl-, BF4-, PF6-, BArf-; 87-92%). The last three salts can also be obtained by anion metatheses of 2+Cl- (77-87%), as can one with the chiral enantiopure anion P(o-C6Cl4O2)3- ((delta)-TRISPHAT-; 81%). The reaction of [(eta5-C5H5)Ru(CO)(NCCH3)2]+PF6- and GBI also gives 2+PF6- (81%). The pentamethylcyclopentadienyl analogues [(eta5-C5Me5)Ru(CO)(GBI)]+X- (3+X-; X- = Cl-, BF4-, PF6-, BArf-; 61-84%) are prepared from (eta5-C5Me5)Ru(PPh3)2(Cl), GBI, and CO followed (for the last three) by anion metatheses. An indenyl complex [(eta5-C9H7)Ru(PPh3)(GBI)]+Cl- (96%) is prepared from (eta5-C9H7)Ru(PPh3)2(Cl) and GBI. All complexes are characterized by NMR (1H, 13C, 31P, 19F, 11B), with 2D spectra aiding assignments. Crystal structures of 1+PF6-·CH2Cl2 and 1+BArf-·CH2Cl2 are determined; the anion is hydrogen bonded to the cation in the former. Complexes 1-3+X- are evaluated as catalysts (10 mol %, RT) for condensations of indoles and trans-beta-nitrostyrene. The chloride salts are ineffective (0-5% yields, 48-60 h), but the BArf- salts exhibit excellent reactivities (97-46% yields, 1-48 h), with the BF4- and PF6- salts intermediate. Evidence for hydrogen bonding of the nitro group to the GBI ligand is presented. GBI shows no catalytic activity; a BArf- salt of methylated GBI is active, but much less so than 2-3+BArf-.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2.

Water-soluble ruthenium complexes [(I?6-arene)Ru(kappa2-L)]n+ (n = 0,1) ([Ru]-1-[Ru]-9) ligated with pyridine-based ligands are synthesized, and the molecular structure of the representative complex [Ru]-2 is confirmed by X-ray crystallography. The studied complexes are employed for the catalytic dehydrogenation of formic acid in water. Screening of these complexes inferred that [Ru]-1 [(I?6-C10H14)Ru(kappa2-NpyOH-L1)Cl]+ (L1 = pyridine-2-ylmethanol) outperformed others with an initial turnover frequency of 1548 h-1. Complex [Ru]-1 also exhibited high stability in water and can be recycled up to seven times with a total turnover number of 6050. In addition to formic acid dehydrogenation, [Ru]-1 also catalyzed the conversion of formaldehyde to hydrogen gas in water under base-free conditions. The effects of temperature, pH, formic acid, and catalyst concentration on the reaction kinetics are investigated in detail. Mass and NMR based mechanistic investigations inferred the presence of several important intermediate species, such as ruthenium-formate species [Ru]-1B and ruthenium-hydride species [Ru]-1C, involved in the catalytic dehydrogenation reaction. Moreover, the molecular structure of a diruthenium species [Ru]-1A? is also authenticated by single-crystal X-ray crystallography.

Ruthenium-assisted cyclizations of two enynes, HC?CCH(OH)(C 6H4)X-CH2CH=CMe2 (X=S (1 a), O (1 b)), each of which contains two terminal methyl substituents on the olefinic parts, are explored. The reaction of 1 a in CH2Cl2 gives the vinylidene complex 2 a from the first cyclization and two side products, 3 a and the carbene complex 4 a with a benzothiophene ligand. The same reaction in the presence of HBF4 affords 4 a exclusively. Air oxidation of 4 a in the presence of Et3N readily gives an aldehyde product. In MeOH, tandem cyclizations of 1 a generate a mixture of the benzothiochromene compound 10 a and the carbene complex 7 a also with a benzothiochromene ligand. First, cyclization of 1 b likewise proceeds in CH2Cl2 to give 2 b. Tandem cyclization of 1 b in MeOH yields comparable products 10 b and 7 b with benzochromene moieties, yet with no other side product. The reaction of [Ru]Cl with HC?CCH(OH)(C6H4)S-CH2CH= CH2 (1 c), which contains no methyl substituent in the olefinic part, in MeOH gives the carbene complex 15 c with an unsubstituted thiochromene by means of a C-S bond formation. Structures of 3 a and 15 c are confirmed by X-ray diffraction analysis. The presence of methyl groups of enynes 1 a and 1 b promotes sequential cyclization reactions that involve C-C bond formation through carbocationic species. Copyright
