Selective Preparation of a Heteroleptic Cyclometallated Ruthenium Complex Capable of Undergoing Photosubstitution of a Bidentate Ligand

Cyclometallated ruthenium complexes typically exhibit red-shifted absorption bands and lower photolability compared to their polypyridyl analogues. They also have lower symmetry, which sometimes makes their synthesis challenging. In this work, the coordination of four N,S bidentate ligands, 3-(methylthio)propylamine (mtpa), 2-(methylthio)ethylamine (mtea), 2-(methylthio)ethyl-2-pyridine (mtep), and 2-(methylthio)methylpyridine (mtmp), to the cyclometallated precursor [Ru(bpy)(phpy)(CH3CN)2]+ (bpy=2,2?-bipyridine, Hphpy=2-phenylpyridine) has been investigated, furnishing the corresponding heteroleptic complexes [Ru(bpy)(phpy)(N,S)]PF6 ([2]PF6?[5]PF6, respectively). The stereoselectivity of the synthesis strongly depended on the size of the ring formed by the Ru-coordinated N,S ligand, with [2]PF6 and [4]PF6 being formed stereoselectively, but [3]PF6 and [5]PF6 being obtained as mixtures of inseparable isomers. The exact stereochemistry of the air-stable complex [4]PF6 was established by a combination of DFT, 2D NMR, and single-crystal X-ray crystallographic studies. Finally, [4]PF6 was found to be photosubstitutionally active under irradiation with green light in acetonitrile, which makes it the first cyclometallated ruthenium complex capable of undergoing selective photosubstitution of a bidentate ligand.

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.name: Dichloro(benzene)ruthenium(II) dimer, you can also check out more blogs about37366-09-9

A highly enantioselective total synthesis of (+)-goniodiol

A high-yielding enantioselective total synthesis of the bioactive styryllactone (+)-goniodiol has been realised, starting from readily available (S)-glycidol. A key step is an oxygen-to-carbon rearrangement of a silyl enol ether linked via an anomeric centre, facilitating the rapid and diastereoselective construction of this functionalised system.

Regiocontrolled Ru-catalyzed addition of carboxylic acids to alkynes: Practical protocols for the synthesis of vinyl esters

The catalytic activity of commercially available, air and water stable ruthenium complexes in the addition of carboxylic acids to terminal alkynes was found to be drastically enhanced by the addition of small quantities of base. Moreover, the regioselectivity of the reaction can be controlled by the choice of the base so that both the Markovnikov (Na2CO3) and the anti-Markovnikov products (DMAP) are now easily accessible in excellent selectivities.

Chemodiscrimination of Olefin Bonds Through Cross-Metathesis Reactions ? Synthesis of Functionalized beta-Lactam and beta-Amino Acid Derivatives

Chemodifferentiation of C=C bonds of various diolefinated beta-lactams or beta-amino esters has been investigated through cross-metathesis reactions. The transformations involved substrate-dependent cross-metathesis of dialkenylated azetidinones, derived from the ring opening of constrained unsaturated bicyclic beta-lactam isomers. Cross-metathesis reactions have been carried out under various conditions and catalysts in view of chemodiscrimination affording functionalized beta-lactams or beta-amino acid derivatives.

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 301224-40-8 is helpful to your research., Reference of 301224-40-8

Thermal study of areneruthenium(II) derivatives

The kinetics of the first step of thermal decomposition were evaluated from the dynamic weight loss data by means of Coats-Redfern, MacCallum-Tanner and Horowitz-Metzger methods. The Dn and Rn models were selected as the models best fitting the experimental TG curves. The values of activation energy, E, and frequency factor, A, of the thermal decomposition were calculated.

Photosensitizing metal-organic framework enabling visible-light-driven proton reduction by a wells-dawson-type polyoxometalate

A simple and effective charge-assisted self-assembly process was developed to encapsulate a noble-metal-free polyoxometalate (POM) inside a porous and phosphorescent metal-organic framework (MOF) built from [Ru(bpy)3]2+-derived dicarboxylate ligands and Zr6(mu3-O)4(mu3-OH)4 secondary building units. Hierarchical organization of photosensitizing and catalytic proton reduction components in such a POM@MOF assembly enables fast multielectron injection from the photoactive framework to the encapsulated redox-active POMs upon photoexcitation, leading to efficient visible-light-driven hydrogen production. Such a modular and tunable synthetic strategy should be applicable to the design of other multifunctional MOF materials with potential in many applications.

eta1-Vinylidene formation from internal alkynones by C-C bond migration

The [mu2-N2(CpRu(PPh3)2) 2]2+ (12+) dication is a source of the formal 16-electron [CpRu(PPh3)2]+ fragment, and it reacts with internal alkynes such as 1,3-diphenylpropynone, 4-phenyl-3-butyn-2- one, and 3-cyclopropyl-1-phenylpropynone to yield eta1-vinylidene complexes 2a+-2c+ by C-C bond activation. In the case of 1,3-diphenylpropynone, the eta1-ketone complex [CpRu(PPh 3)2{PhC(eta1-O)C?CPh}]+ (3a+) was isolated as its PF6- salt, and it is apparently an intermediate in the formation of the vinylidene complex. Complexes 2a+-2c+ were characterized as their BArF 4- [ArF = 3,5-bis(trifluoromethyl)phenyl] salts by NMR and IR spectroscopic methods, ESI-MS, and EA. The single crystal X-ray diffraction structure of 2aBArF4 is presented. These reactions represent the first examples where an internal alkyne undergoes C-C bond migration to form an eta1-vinylidene complex. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Dihydrogen complexes of ruthenium. 2. Kinetic and thermodynamic considerations affecting product distribution

Cationic ruthenium dihydrogen complexes of the form [(eta-C5H5)Ru(L)(L?)(eta2-H 2)]BF4 (L = CO, L? = PCy3 (1a), PPh3 (2a), PMe2Ph (3a), PMe3 (4a) have been prepared by protonation of the corresponding neutral hydrides. Carbonyl free derivatives such as [(eta-C5H5)Ru(P P?)(eta2-H2)]BF4 (P P? = 1,2-bis(dimethylphosphino)ethane (dmpe) (5a), (1,1-dimethyl-2,2-diphenylphosphino)ethane (dmdppe) (6a), (R)-(+)-1,2-bis(diphenylphosphino)propane ((R)-prophos) (8a), bis(PPh3) (9a)) were similarly prepared. Pentamethylcyclopentadienyl analogues [(eta-C5Me5)Ru(P P?(eta2-H2)]BF4 (P P? = dmdppe (7a), (PPh3J2 (10a)) and [(eta-C5Me5)Ru(CO)(PCy3)(eta 2-H2)]BF4 (11a) have also been prepared. Identification of these species as dihydrogen complexes is based upon observation of substantial H-D coupling (22-32 Hz) in the 1H NMR spectra of the HD analogues, prepared by protonation of the corresponding deuterides. In every case studied in detail, the kinetic product of the protonation reaction is the dihydrogen complex, but an intramolecular isomerization occurs to give variable amounts of the transoid dihydride form at equilibrium. The composition of the equilibrium mixture and the rate at which the equilibrium is obtained depend upon the ligand environment. Facile rotation of the coordinated H2 ligand in the ruthenium complexes is established by the study of chiral complexes. The coordinated H2 in these complexes is substantially activated toward heterolytic cleavage. In the case of 5a, the measured pKa is 17.6 (CH3CN), with the dihydrogen form deprotonated more rapidly than the dihydride.
