Half-sandwich ruthenium, rhodium and iridium complexes of triazolopyridine ligand: Synthesis and structural studies

Triazolopyridine ligand, {3-(2-pyridyl)-[1,2,3]triazolo[1,5-a]-pyridine}, L was synthesized by reaction of p-toulenesulphonyl hydrazine and dipyridyl ketone in the presence of acetic acid. Half-sandwich ruthenium, rhodium and iridium complexes [1?4] have been synthesized by reaction of [{(arene)MCl 2} 2] (arene = p-cymene/benzene/Cp* and M = Ru/Rh/Ir) with ligand L in methanol. The reaction in 1:2 (M:L) ratio has yielded all mononuclear cationic complexes such as [(arene)MLkappaN?N2Cl]PF 6, where {(arene)M} = (p-cym)Ru (1), (benz)Ru (2), Cp*Rh (3) and Cp*Ir (4). All the complexes were characterized by spectral studies and the solid state structures of complexes, 1 and 3 were unambiguously determined by crystallographic studies.

Organometallic complexes supported on a metal-oxide cluster. pH-dependent interconversion between the monomeric and dimeric species of the polyoxoanion-supported [(arene)Ru]2+ complex

Keggin polyoxometalate (POM)-supported two (arene)Ru2+ complexes, i.e., the monomeric species (type-m) [{(arene)Ru(H 2O)}PW11O39]5- and the dimeric species (type-d) [({(arene)Ru}PW11O39)2(mu- WO2)]8-, were prepared as water-soluble Et 2NH2+ salts by pH-controlled reactions in aqueous solutions of the in situ-generated, mono-lacunary Keggin POM [PW 11O39]7- with the organometallic precursor [{RuCl2(arene)}2]. The effects of the arene (benzene (1), toluene (2), p-cymene (3), and hexamethylbenzene (4)) on the proportion of the type-m to type-d complex produced were examined. pH-Varied 31PNMR spectroscopy showed that there was a pH-dependent interconversion between type-m and type-d complexes, i.e., the ratio of the dimeric species increased as pH of the solution was lowered. Under the reaction conditions, the dimeric species d1, d3, and d4 as water-soluble Et2NH2+ salts were successfully isolated as the major products. It was concluded that (1) steric repulsion between the two (arene)Ru2+ fragments in the dimeric species was not significant, (2) the proportion was strongly dependent on the pH of the solution rather than the bulkiness of the arene, and (3) the use of the in situ-generated [PW11O39]7-, but not the isolated lacunary species, such as K7[PW11O 39]¡¤nH2O, had an effect on the reaction.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Reference of 37366-09-9

Bifunctional [c2]daisy-chains and their incorporation into mechanically interlocked polymers

A strategy for the formation of mechanically interlocked polymers is presented. Ring-closing olefin metathesis has been shown to provide a very high yielding route to [c2]daisy-chains suitably functionalized to allow their one-step conversion to bisolefins which can be used as monomers in ADMET polymerizations to afford mechanically interlocked polymers. Metathesis, in two different guises is making a hitherto unreachable goal in synthesis a reality. Copyright

Synthesis of fused multicyclic compounds containing macrocycles by dienyne ring-closing metathesis and Diels-Alder reactions

Fused bicyclic compounds comprising small and large rings were synthesised by dienyne ring-closing metathesis (RCM) using Grubbs’ catalyst. By taking advantage of faster small ring cyclisation compared with macrocyclisation, single isomers were obtained rather than mixtures of two isomers with different ring sizes. Using this process, various fused bicyclic compounds comprising small rings (5-7- membered) and large rings (14-17- membered) were obtained. By increasing reaction temperature and catalyst loading, the product conversion was improved in a predicted manner. This method produced E-olefins on the macrocycles with high selectivity. Also, the selectivity issues of tandem RCM for the synthesis of fused bicyclic compounds comprising small and medium rings were investigated. Lastly, the prepared bicyclic compounds with small and large rings contained 1, 3-dienes that underwent a further modification reaction, such as Diels-Alder, to produce more complex compounds. These Diels-Alder reactions produced tri- and tetracyclic compounds containing a macrocycle with single diastereomers, suggesting that the methodology demonstrated here could be a powerful tool for rapid preparation of highly complex molecules.

Total Syntheses of Thailanstatins A-C, Spliceostatin D, and Analogues Thereof. Stereodivergent Synthesis of Tetrasubstituted Dihydro- and Tetrahydropyrans and Design, Synthesis, Biological Evaluation, and Discovery of Potent Antitumor Agents

Efficient and selective total syntheses of spliceosome modulating natural products thailanstatins A-C and spliceostatin D are reported. A number of stereoselective methods for the construction of various tetrasubstituted dihydro- and tetrahydropyrans were developed as a prerequisite for the syntheses of these naturally occurring molecules and variations thereof. The pyran-forming reactions utilize a Heck/Saegusa-Ito cascade sequence to generate hydroxy alpha,beta,gamma,delta-unsaturated aldehyde precursors followed by a catalyst-controlled oxa-Michael cyclization to furnish tetrasubstituted dihydropyrans with high stereocontrol. Subsequent optimized homogeneous or heterogeneous hydrogenations of these dihydropyran systems afford their tetrahydropyran counterparts, also in a highly stereoselective manner. The synthesized thailanstatins and related analogues were biologically evaluated for their cytotoxic properties, leading to the identification of a number of compounds with exceptionally potent antitumor activities suitable for further development as potential antibody-drug conjugate payloads, single drugs, or drug combinations for cancer therapies. Important structure-activity relationships within the thailanstatin family and structurally related compounds are discussed and are expected to be path-pointing for future studies.

Aarene platinum group metal complexes containing imino-quinolyl ligands: synthesis and antibacterial studies

Imino-quinolyl Schiff-base ligands have been prepared by the condensation reaction of substituted 2-aminopyridine and quinoline-2-carbaldehyde. The reaction of [(arene)MCl2]2 with imino-quinolyl Schiff-base ligands leads to the formation of cationic complexes [(arene)M(L)Cl]+ (1?12). Single crystal X-ray diffraction studies were used to confirm the coordination mode and structures of these complexes. The molecular structures of these complexes revealed that they adopt characteristic three-legged piano stool geometry with the metal coordinating through a terminal chloride and imino-quinolyl ligands in a bidentate chelating NN? fashion. The ligand coordinates to the metal center through the nitrogen of the quinoline and the imine nitrogen forming a five-membered metallacycle. These compounds were evaluated for their in?vitro antibacterial activity by the agar well diffusion method against Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae strains. Results show that all the ligands and complexes inhibited the growth of bacteria.

Oximated ruthenium tris-bipyridyl complex: Synthesis and luminescent response specifically for ClO- in water containing multiple ions

Hypochlorite has been widely and essentially used as the disinfecting agent of water in our daily life. Rapidly, specifically, quantitatively and simply monitoring ClO- in water remains to be investigated and is of importance. For this purpose a novel complex bis(2,2?-bipyridine)(4?-methyl-2,2?-bipyridyl-4-carbaldehyde oxime)ruthenium chloride (Ru-CN-OH) was prepared. In water, reaction of complex Ru-CN-OH and ClO- results in bis(2,2?-bipyridine)(4?-methyl-2,2?-bipyridyl-4-carboxylic acid)ruthenium (Ru-CO2H) and thereby offers an efficient luminescence response. This was ascertained to be a specific oxidation reaction of complex Ru-CN-OH with ClO-, and can be used for quantitatively monitoring aqueous ClO-. The product of the oxidation reaction of complex Ru-CN-OH and ClO- was isolated and assigned to Ru-CO2H. The luminescent emission spectra of complex Ru-CN-OH in the presence of ClO- demonstrated that the coexistence of F-, Cl-, Br-, I-, HCO3-, HSO4-, H2PO4-, S2O32-, SO32-, CO32-, PO43-, HPO42-, NO3-, AcO-, Li+, Na+, K+, Ca2+, Mg2+, Zn2+, Co2+, Fe3+, Ni2+, Pb2+, Hg2+, Mn2+ and Cu2+ did not interfere in the quantitative change of the intensity of the luminescent emission.

Automated synthesis of 3?-metalated oligonucleotides

We report the first synthesis ofa metallonucleoside bound to a solid support and subsequent oligonucleotide synthesis with this precursor. Large-scale syntheses of metal-containing oligonucleotides are achieved using a solid support modified with [Ru(bpy)2(impy?)]2+ (bpy is 2,2?-bipyridine; impy? is 2?-iminomethylpyridyl-2?-deoxyuridine). A duplex formed with the metal-containing oligonucleotide exhibits superior thermal stability when compared to the corresponding unmetalated duplex (Tm = 50 C vs Tm = 48 C). Electrochemical (E1/2 = 1.3 V vs NHE), absorption (lambdamax = 480 nm), and emission (lambdamax = 720 nm, tau = 44 ns, Phi = 0.11 ¡Á l0-3) data for the ruthenium-modified oligonucleotides indicate that the presence of the oligonucleotide does not perturb the electronic properties of the ruthenium complex. The absence of any change in the emission properties upon duplex formation suggests that the [Ru(bpy)2(impy)]2+ chromophore will be a valuable probe for DNA-mediated electron-transfer studies. Despite the relatively high Ru(III/II) reduction potential, oxidative quenching of photoexcited [Ru(bpy)2(impy)]2+ does not lead to oxidative damage of guanine or other DNA bases.
