Redox responsive bi/tri-nuclear complexes incorporating ferrocenyl unit: Synthesis, characterization, physicochemical studies and X-ray structure of [C5H5FeC5H4CH = CHC5H4N-CH3]PF6 with a mirror creating disorder

(Trans-1-(4-pyridyl)-ethylene) ferrocene, L reacts with K[RuIII(edtaH)]Cl to form binuclear complex. K[RuIII(edtaH)]Cl exist as RuIII(edtaH)(H2O) in aqueous solution and substitution of the aqua molecule by L occurs within the stopped flow time scale. Rate constants for the reaction are 1620 ¡À 20, 2080 ¡À 35, 2690 ¡À 50 M-1 s-1 at 28, 34 and 39.9C, respectively [DeltaH# is 30.3 ¡À 1.1 kJ mol-1 and DeltaS# is -124 ¡À 4 J K-1 mol-1]. RII(2,2?-bipy)2Cl2 reacts with L to form bi/trinuclear complexes, [RuII(2,2?-bipy)2LCl]PF6 and [RuII(2,2?-bipy)2L2](PF6)2, depending on the reaction conditions. Luminescence of the RuII(2,2?-bipy)2(py)2+2 center in the trinuclear complexes is completely quenched presumably through energy transfer pathway. There exist a moderate to weak electrochemical interaction between the two redox centers either in N-methylated form of L or in the bi/trinuclear complexes derived from Ru(II) or Ru(III). All these new bi/trinuclear complexes are characterized by physicochemical methods. Single crystal X-ray structure of [L-CH3]PF6 is reported. A very low value of powder SHG efficiency observed earlier for this salt can now be well understood in terms of the centrosymmetric molecular arrangement created due to the disorder in the crystal.

Metal-polypyridyl complexes with pendant adenine and thymine groups as building blocks for hydrogen-bonded supramolecular assemblies

Reaction of 5-bromomethyl-2,2?-bipyridine with adenine or thymine afforded mixtures of N-alkylated products, from which the ligands bipy-A [in which the adenine is alkylated at the N(9) position] and bipy-T [in which the thymine is alkylated at the N(1) position] could be isolated; these were used to prepare [Ru(bipy)2(bipy-A)[PF6]2 and [Os(bipy)2 (bipy-T)][PF6]2 (of which the former was crystallographically characterized) in which the adenine and thymine fragments are pendant from the {M(bipy)3}2+-type core.

Metal-ion dependent reactivity of 2-(2′-thienyl)pyridine (Hthpy)

The reaction of 2-(2’thienyl)pyridine (Hthpy) with palladium acetate results in a clean conversion to the mu-acetato-bridged dimeric cyclometallated complex <(thpy)Pd(mu-OAc)Pd(thpy)> in which a new Pd-C bond is formed at the 3′ position of the thienyl ring.In contrast, treatment with Na under similar conditions only results in the formation of the complex <(HL)AuCl3> in which the ligand acts as a monodentate N-donor.At higher temperatures the reaction of Na with Hthpy yields a complex mixture of products, including complexes of 2-(5′-chloro-2′-thienyl)pyridine and 5,5′-bis(2-pyridyl)-2,2′-bithienyl.Independent syntheses of these latter compounds have confirmed their identities.The reaction of 2-(2’thienyl)pyridine with (bpy = 2,2′-bypyridine) in the presence of a chloride ion abstractor yields salts of the cation 2+ which contains a bidentate N,S-bonded ligand.

Ruthenium-diimine type complex as well as preparation method and application thereof

The invention relates to a ruthenium-diimine type complex as well as a preparation method and application thereof. The method comprises the following steps: i, dissolving 2-pyridine carboxaldehyde and2-aminochrysene into absolute ethyl alcohol, and heating and stirring under the protection of nitrogen gas; adding a ruthenium complex precursor Ru(bpy)2Cl2; heating and refluxing overnight under theprotection of the nitrogen gas; after raw materials are completely transformed, stopping heating; cooling to room temperature and concentrating; adding a methanol saturated solution of ammonium hexafluorophosphate into a concentrated solution; transferring a reaction mixture into a sand plate funnel for suction filtration, and washing; dissolving a crude product into acetone and taking n-hexane as a dispersion agent for recrystallizing, so as to obtain a ruthenium-diimine type complex pure product. The ruthenium-diimine type complex provided by the invention has the advantages of simple preparation method and relatively high yield and purity; after a ligand is synthesized, the ligand does not need to be subjected to separation treatment and can directly react with a ruthenium precursor toobtain a target product. The ruthenium-diimine type coordination complex has a wide application prospect in the fields including catalysis, sensing, molecular recognition and the like.

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.Product Details of 15746-57-3, you can also check out more blogs about15746-57-3

Nanoscale Metal?Organic Layers for Deeply Penetrating X-ray-Induced Photodynamic Therapy

We report the rational design of metal?organic layers (MOLs) that are built from [Hf6O4(OH)4(HCO2)6] secondary building units (SBUs) and Ir[bpy(ppy)2]+- or [Ru(bpy)3]2+-derived tricarboxylate ligands (Hf-BPY-Ir or Hf-BPY-Ru; bpy=2,2?-bipyridine, ppy=2-phenylpyridine) and their applications in X-ray-induced photodynamic therapy (X-PDT) of colon cancer. Heavy Hf atoms in the SBUs efficiently absorb X-rays and transfer energy to Ir[bpy(ppy)2]+ or [Ru(bpy)3]2+ moieties to induce PDT by generating reactive oxygen species (ROS). The ability of X-rays to penetrate deeply into tissue and efficient ROS diffusion through ultrathin 2D MOLs (ca. 1.2 nm) enable highly effective X-PDT to afford superb anticancer efficacy.

Ruthenium-catalyzed oxidative cyanation of tertiary amines with molecular oxygen or hydrogen peroxide and sodium cyanide: Sp3 C-H bond activation and carbon-carbon bond formation

Ruthenium-catalyzed oxidative cyanation of tertiary amines with molecular oxygen in the presence of sodium cyanide and acetic acid gives the corresponding alpha-aminonitriles, which are highly useful intermediates for organic synthesis. The reaction is the first demonstration of direct sp3 C-H bond activation alpha to nitrogen followed by carbon-carbon bond formation under aerobic oxidation conditions. The catalytic oxidation seems to proceed by (i) alpha-C-H activation of tertiary amines by the ruthenium catalyst to give an iminium ion/ruthenium hydride intermediate, (ii) reaction with molecular oxygen to give an iminium ion/ruthenium hydroperoxide, (iii) reaction with HCN to give the alpha-aminonitrile product, H2O2, and Ru species, (iv) generation of oxoruthenium species from the reaction of Ru species with H2O2, and (v) reaction of oxoruthenium species with tertiary amines to give alpha-aminonitriles. On the basis of the last two pathways, a new type of ruthenium-catalyzed oxidative cyanation of tertiary amines with H2O2 to give alpha-aminonitriles was established. The alpha-aminonitriles thus obtained can be readily converted to alpha-amino acids, diamines, and various nitrogen-containing heterocyclic compounds.
