New ruthenium(II) complexes bearing N-heterocyclic carbenes

N-heterocyclic carbene complexes of ruthenium(II), [CpRu(L*)2Cl] (2) and [CpRu(CO)(L*)-Cl] (3) (Cp = eta5-C5H5; L* = l,3-dicyclohexyl-imidazolin-2-ylidene), have been obtained in high yields by reaction of [CpRu(PR2R?)2Cl] (R = R? = Ph, la; R = Ph, R? = 2-MeC6H4, 1b) and [CpRu(CO){PPh2(2-MeC6H4)}Cl] (1c), respectively, with the free carbene L*. The mixed dicarbene complex [CpRu(=CPh2)(L*)Cl] (4) is prepared from [CpRu(=CPh2){PPh2(2-MeC6H4-Cl] (1d) and an equimolar amount of L*, whereas subsequent reaction of 1d with L* leads to formation of 2, along with tetraphenylethene. The reaction of [Cp*Ru(PPh3)2Cl] (1e) with L* gives the pentamethylcyclopentadienyl derivative [Cp*Ru(PPh3)(L*)Cl] (5) (Cp* = eta5-C5Me5) by displacement of 1 equiv of PPh3 Complex 5 reacts in toluene with CO, pyridine (Py), and N2CHCO2Et, affording [Cp*Ru(CO)(L*)Cl] (6), [Cp*Ru(Py)(L*)Cl] (7), and the mixed dicarbene [Cp*Ru(=CHCO2Et)(L*)Cl] (8), which were isolated in high yields. The molecular structure of complex 6 has been determined by an X-ray investigation, and the carbene-ruthenium distance clearly indicates a single bond (2.0951(18) A). The N-heterocyclic carbene does not undergo substitution by other two-electron ligands.

Ferrocenoyl pyridine arene ruthenium complexes with anticancer properties: Synthesis, structure, electrochemistry, and cytotoxicity

Organometallic ruthenium(II) complexes of general formula [Ru(eta6-arene)Cl2(NC5H4OOC-C 5H4FeC5H5)], where arene = C 6H6 (1), C6H5Me (2), p- iPrC6H4Me (3), and C6Me6 (4), and of general formula [Ru(eta6-arene)Cl2] 2(NC5H4OOC-C5H4FeC 5H4-COOC5H4N), where arene = p- iPrC6H4Me (5) and C6Me6 (6), have been synthesized and characterized, the molecular structures of these complexes being confirmed by single-crystal X-ray structure analysis of complex 4 as a representative example. The redox properties and in vitro anticancer activities of complexes 1-6 have been studied. All the compounds are moderately cytotoxic toward the A2780 and A2780cisR (cisplatin-resistant) human ovarian carcinoma cell lines. The diruthenium arene complexes 5 and 6 are about twice as active as their mononuclear analogues 3 and 4. Cyclic voltammetry revealed a good correlation of the RuII/RuIII redox potentials of 1-4 and the number of alkyl substituents in the arene ligand.

Total synthesis and cytotoxic activity of dechlorogreensporones A and D

The first and convergent total syntheses of polyketide natural products dechlorogreensporones A and D have been accomplished in 17 longest linear steps with 2.8% and 5.4% overall yields, respectively, starting from known methyl 2-(2-formyl-3,5-dihydroxyphenyl)acetate and commercially available R-(+)-propylene oxide and 1,2-epoxy-5-hexene. Our synthesis exploited key Mitsunobu esterification and (E)-selective ring-closing metathesis (RCM) to assemble the macrocycles as well as a Jacobsen hydrolytic kinetic resolution to install the stereogenic centers. Both synthetic compounds were found to display significant cytotoxic activity against seven human cancer cell lines with the IC50 ranges of 6.66?17.25 muM.

Synthesis of 6-Hydroxysphingosine and alpha-Hydroxy Ceramide Using a Cross-Metathesis Strategy

(Chemical Equation Presented) In this paper, a new synthetic route toward 6-hydroxysphingosine and alpha-hydroxy ceramide is described. The synthesis employs a cross-metathesis to unite a sphingosine head allylic alcohol with a long-chain fatty acid alkene that also bears an allylic alcohol group. To allow for a productive CM coupling, the sphingosine head allylic alcohol was protected with a cyclic carbonate moiety and a reactive CM catalyst system, consisting of Grubbs II catalyst and CuI, was employed.

The structure of these complexes characterized by spectroscopic studies were supported by their optimized geometries based on DFT calculations. Complexes 1 and 2 were then allowed to interact with methanolic solution of sodium perchlorate separately providing corresponding complexes 3 and 4 with the compositions 1¡¤NaClO4 and 2¡¤NaClO4, respectively. The formation constants were then evaluated by monitoring the changes in their UV-visible spectral features upon addition of different amount of sodium salts in the presence of a fixed concentration of the ruthenium complexes at a wavelength 294 nm. Emission (solution), luminescence microscopic and cyclic voltammetric studies of these complexes have also been made.

Visible light-assisted reduction of CO2 into formaldehyde by heteroleptic ruthenium metal complex-TiO2 hybrids in an aqueous medium

The photocatalytic reduction of CO2 with its simultaneous functionalization is a profound journey to achieve under an ambient condition. In the current research, precedence exists for the formation of HCHO, HCOOH, CO, CH4, and CH3OH after the reduction of CO2 under suitable conditions. In this progression, HCHO is considered to be a reactive molecule, which occurs in the photocatalysis under suitable condition observed in the photocatalytic process. Herein, we report CO2 reduction to formaldehyde via heterogeneous photocatalysis in an aqueous medium at pH 7. The as-synthesized hybrid photocatalyst is capable of being active under visible light (lambda > 420 nm) by utilizing the heteroleptic ruthenium metal complex over TiO2 nanoparticles via covalent interactions. The major reaction product was identified as formaldehyde, while trace amounts of CO and CH4 were also detected in the presence of triethanolamine (TEOA) as a sacrificial donor. The maximum turnover number (720) for HCHO was obtained based on the metal complex used over the surface after 5 h visible light irradiation. Furthermore, formaldehyde (in situ) was utilized for the reaction with primary amines (aniline, 4-aminobenzoic acid) to form the corresponding imines under visible light. Directed by mechanistic studies, the results indicate for the first time that the C1 reduced product of CO2 in a heterogeneous medium can be utilized for synthesis of useful products.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 15746-57-3, you can also check out more blogs about15746-57-3

Synthesis and characterization of mononuclear indoline complexes. Studies of sigma and pi bonding modes

The dication [(cymene)Ru(eta6-1-Me-indoline)]2+, 1a, has been synthesized either by the hydrogenation of [(cymene)Ru(1-Me-indole)]2+ or by the reaction of [(cymene)Ru(OTf)2]x with 1-Me-indoline and has been isolated as the triflate or tetraphenylborate salt. Other [(arene)- Ru(indoline)]2+ derivatives have also been prepared by similar methods. [1a](BPh4)2 crystallized in the space group P1 with a = 10.9308(3) A, b = 14.1874(4) A, c = 18.4139(5) A, alpha = 81.800(1), beta= 75.17, gamma = 89.50, V = 2731.19(13) A3, and Z = 2. The sandwich structure is slightly bent with an angle between the ruthenium ion and the center of each eta6-ligand of 174.3. Complexes with eta1-N-coordinated indoline ligands have also been characterized. The reaction of indoline with Pd(Cl)2(PPh3)(CH3CN) in refluxing dichloromethane resulted in the formation of (Cl)2(PPh3)Pd(eta1-indoline), 2, which was isolated and characterized by spectroscopic methods. Complex 2 crystallized in the space group P1 with a = 9.703(2) A, b = 10.148(2) A, c = 13.920(2) A, alpha = 99.650(10), beta = 99.230(10), gamma = 94.560(10), V = 1325.8(3) A3, and Z = 2. The indoline ligand is tilted with respect to the metal-ligand plane, and the five-membered ring of the ligand assumes an envelope-type conformation.
