Reference of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.

A family of {Ru(arene)}2+-containing heteropolytungstates of general formula [{Ru(L)}2(alpha-XW11O39) 2WO2]m- (L = benzene, p-cymene; X = Ge IV, SiIV, m = 10; X = BIII, m = 12) has been prepared in aqueous acidic medium (pH ? 4). The 1:1 interaction of [Ru(C 6H6)Cl2]2 or [Ru(p-cymene)Cl 2]2 with [beta2-GeW11O 39]8- led to the formation of [{Ru(benzene)} 2(GeW11O39)2WO2] 10- (1) and [{Ru(p-cymene)}2(GeW11O 39)2WO2]10- (2), respectively. Replacing [beta2-GeW11O39]8- by [alpha-SiW11O39]8- resulted in [{Ru(benzene)}2(SiW11O39)2WO 2]10- (3) and [{Ru(p-cymene)}2(SiW 11O39)2WO2][SiW12O 40]0.512- (4), respectively. The reaction of [alpha-HBW11O39]8- with the respective {Ru(arene)}2+-containing precursors resulted in polyanions [{Ru(benzene)}2(HBW11O39)2WO 2]10- (5) and [{Ru(p-cymene)}2(HBW 11O39)2WO2]10- (6), respectively. Single-crystal XRD analysis of the hydrated salts of 1-6 revealed that these species comprise two Keggin fragments, [{Ru(L)}alpha-XW 11O39]6- (L = benzene, p-cymene; X = Ge IV, SiIV) for polyanions 1-4 and [{Ru(L)}alpha-HBW 11O39]6- (L = benzene, p-cymene) for 5 and 6, connected via a cis-dioxo {WO2}2+ unit. In addition, the heteropolytungstates were characterized by thermogravimetric analysis, IR spectroscopy, elemental analysis, and solution electrochemical studies. Copyright

Second generation Grubbs catalyst [RuCl2(H2IMes)(PCy3)(CHPh)] initiates regio- and stereoselective cross-metathesis of silylacetylenes with 1-alkenes and alpha,omega-dienes leading to the formation of E-2-silyl-1,3-dienes and E-2-silyl-1,3,n-trienes, respectively. Efficient progress of the reaction is achieved by using 5-8 mol% of the benzylidene initiator and twofold excess of olefin (with respect to silylacetylene) as well as ethereal solution of HCl (10-20 mol% with respect to the catalyst) as an activator. The reaction is proposed to be catalysed by alkylidene complex [RuCl2(H2IMes)(PCy3)(CHR)] (where R = alkyl, n-alkenyl) generated from the benzylidene initiator, and proceed via initial interaction of a metal alkylidene with a triple bond.

Photoelectrochemical studies of RuS2-coated TiO2 electrodes showed semiconductor sensitization by RuS2 fine particles on TiO2.RuS2 particles of ca. 100 nm size were observed from a scanning electron micrograph of the RuS2/TiO2 electrode surface.RuS2-coated TiO2 electrodes showed continuous wide absorption in the visible spectral region.Photoelectrochemical measurements of several RuS2/TiO2 electrodes, prepared under different conditions, were carried out.The electron-transfer efficiency from RuS2 to TiO2 was affected by the number of RuS2 colloid coatings and the preparation temperature of the RuS2 colloids.A schematic study was carried out on the effect of a heat treatment in order to find the optimum temperature for the maximum sensitization efficiency.A comparison of the absorption of the absorption and action spectra of the RuS2/TiO2 electrode showed that only small RuS2 particles with a critical size distribution could transfer the photo-generated electrons to TiO2.A band-gap value of ca. 2.8 eV was evaluated (from the photocurrent action spectrum) for the RuS2 particles with high sensitization efficiency.A scheme which shows the energy diagram for RuS2 fine particles has been proposed by considering the flat-band potential values derived from the photocurrent onset potentials and the above-mentioned band-gap value.

Methynolide and 10-epi-methynolide were synthesized from the necessary segments, which were prepared by the addition of Grignard reagents to the corresponding alpha-alkoxyketones utilizing 1,2-stereochemical selection based on Cram chelation control. Ring-closing metathesis, as the key reaction, was carried out to combine the segments for the synthesis of methynolide and 10-epi-methynolide. The total synthesis of methymycin was also achieved by the glycosylation of methynolide with the trichloroimidate derivative of d-desosamine.

The reaction of [(eta6-C6H6)RuCl2]2 with the sodium salt of (+)(S)-N-(1-phenylethyl)-pyrrolecarbaldimine (HLL*) in CH2Cl2 yielded a mixture of the two diastereomers (SRu,SC)-and (RRu,SC)-[(eta6-C6H 6)Ru(LL*)Cl] (1a,b) in a ratio of 68:32. The chloride ligand in 1a,b was replaced in methanol by triphenylphosphane to give the two diastereomers (SRu,SC)-and (RRu,SC)-[eta6-C6H 6)Ru(LL*)(PPh3)]PF6 (2a,b). According to variable-temperature 1H NMR studies the formation of configurationally labile solvate intermediates has to be assumed in the reaction of the chloro complexes 1a,b with triphenylphosphane in the solvent methanol. In contrast to the diastereomers 1a,b, the ruthenium configuration in the phosphane complexes 2a,b is configurationally stable at room temperature. The diastereomers 2a,b were separated by crystallization. The crystal structures of (SRu,SC)-1a, (SRu,SC)-2a, and (RRu,SC)-2b were determined by X-ray analysis. The epimerization of 2b at 85 C in nitromethane-d3 gave a 93.5:6.5 equilibrium mixture of 2a and 2b (tau1/2 (min) = 58.2 ± 0.4). Conformational analyses showed that two main factors govern the orientation of the 1-phenylethyl group relative to the [(eta6-C6H6)Ru(LL*)X] moiety (X = Cl, PPh3): (i) the faceon orientation of the phenyl substituent with respect to the pi-bonded benzene ligand and (ii) the orientation of the hydrogen substituent toward the unidentate ligand L.

Polymerization of a series of acetylenes with a hydroxy functional group was investigated by using modified 2nd generation Grubbs (A) and Grubbs-Hoveyda (B) initiators. Owing to excellent tolerance for polar functional groups, catalysts A and B polymerized 3-butyn-2-ol (1), 2-methyl-3-butyn-2-ol (2) and 3-butyn-1-ol (3). The catalytic activities of catalyst B were greater than those of initiator A for these polymerizations. The steric bulk and the position of hydroxyl group of the monomer had an influence on the rate of polymerization. In order to investigate the role of hydroxyl group of monomers in the polymerization, the reaction between hydroxyacetylenes and the ruthenium complexes were monitored by 1H NMR spectroscopy. The results revealed the formation of new alkylidene species via alpha-insertion. The calculated relative energies of propagating species formed in the reaction of A with monomer 1 suggested the formation of oxygen-chelated species. The structures of resulting polymers were characterized by various methods such as NMR, IR and UV-Vis spectroscopies. The ruthenium initiators gave polymers with different geometric structure of main chain than conventional catalysts.

Four half-sandwich ruthenium(II) complexes [(eta6-C6H6)Ru(L1-O)][PF6] (1), [(eta6-C6H6)Ru(L2-O)][PF6] (2), [(eta6-C6H6)Ru(L3-O)][PF6] (3), [(eta6-C6H6)Ru(L4-O)][PF6] (4a), and [(eta6-C6H6)Ru(L4-O)][BPh4] (4b) [L1-OH, 4-nitro-6-{[(2?-(pyridin-2-yl)ethyl)methylamino]methyl}-phenol; L2-OH, 2,4-di-tert-butyl-6-{[(2?-(pyridin-2-yl)ethyl)methylamino]methyl}-phenol; L3-OH, 2,4-di-tert-butyl-6-{[2?-((pyridin-2-yl)benzylamino)methyl}-phenol; L4-OH, 2,4-di-tert-butyl-6-{[(2?-imethylaminoethyl)methylamino]methyl}-phenol (L4-OH)], supported by a systematically varied series of tridentate phenolate-based pyridylalkylamine and alkylamine ligands are reported. The molecular structures of 1-3, 4a, and 4b have been elucidated in solution using 1H NMR spectroscopy and of 1, 3, and 4b in the solid state by X-ray crystallography. Notably, due to coordination by the ligands the Ru center assumes a chiral center and in turn the central amine nitrogen also becomes chiral. The 1H NMR spectra exhibit only one set of signals, suggesting that the reaction is completely diastereoselective [1: SRu,SN/RRu,RN; 2: RRu,RN/SRu,SN; 3: SRu,RN/RRu,SN; 4b: SRu,RN/RRu,SN]. The crystal packing in 1 and 3 is stabilized by C-H…O interactions, in 4b no meaningful secondary interactions are observed. From the standpoint of generating phenoxyl radical, as investigated by cyclic voltammetry (CV), complex 1 is redox-inactive in MeCN solution. However, 2, 3, and 4a generate a one-electron oxidized phenoxyl radical coordinated species [2]2+{radical dot}, [3]2+{radical dot}, and [4a]2+{radical dot}, respectively. The radical species are characterized by CV, UV-Vis, and EPR spectroscopy. The stability of the radical species has been determined by measuring the decay constant (UV-Vis spectroscopy).
