Ru-II and Ru-III Chloronitrile Complexes: Synthesis, Reaction Chemistry, Solid State Structure, and (Spectro)Electrochemical Behavior

The synthesis of [Ti6O4(OiPr)(8)(O2CPh)(8)] (3) and [RuCl(N equivalent to CR)(5)][RuCl4(N equivalent to CR)(2)] (4a, R = Me; 4b, R = Ph), [Ru(N equivalent to CPh)(6)][RuCl4(N equivalent to CPh)(2)] (5) and [H3O][RuCl4(N equivalent to CMe)(2)] (7a) is discussed. Crystallization of 5 from CH2Cl2 gave trans-[RuCl2(N equivalent to CPh)(4)] (6). The solid-state structures of 3, 4a,b, 5, 6 and 7a are reported. Complex 4b forms a 3D network, while 6 displays a 2D structure, due to pi-interactions between the benzonitrile ligands. The (spectro)electrochemical behavior of 4a,b and 6 was studied at 25 and -72 degrees C and the results thereof are compared with [NEt4][RuCl4(N equivalent to CMe)(2)] (7b) and [RuCl(N equivalent to CPh)(5)][PF6] (8). The electrochemical response of the cation and the anion in 4a,b are independent from each other. [RuCl(N equivalent to CR)(5)](+) possesses one reversible Ru-II/Ru-III process. However, [RuCl4(N equivalent to CMe)(2)](-) was shown to be prone to ligand exchange and disproportionation upon formation of either a Ru-IV and Ru-II species at 25 degrees C, while at -72 degrees C the rapid conversion of the electrochemically formed species is hindered. In situ IR and UV/Vis/NIR studies confirmed the respective disproportionation reaction products of the aforementioned oxidation and reduction, respectively.

Free radical generation induced by ultrasound in red wine and model wine: An EPR spin-trapping study

Direct evidence for the formation of 1-hydroxylethyl radicals by ultrasound in red wine and air-saturated model wine is presented in this paper. Free radicals are thought to be the key intermediates in the ultrasound processing of wine, but their nature has not been established yet. Electron paramagnetic resonance (EPR) spin trapping with 5,5-dimethyl-l-pyrrolin N-oxide (DMPO) was used for the detection of hydroxyl free radicals and 1-hydroxylethyl free radicals. Spin adducts of hydroxyl free radicals were detected in DMPO aqueous solution after sonication while 1-hydroxylethyl free radical adducts were observed in ultrasound-processed red wine and model wine. The latter radical arose from ethanol oxidation via the hydroxyl radical generated by ultrasound in water, thus providing the first direct evidence of the formation of 1-hydroxylethyl free radical in red wine exposed to ultrasound. Finally, the effects of ultrasound frequency, ultrasound power, temperature and ultrasound exposure time were assessed on the intensity of 1-hydroxylethyl radical spin adducts in model wine.

Double Spirocyclization of Arylidene-Delta(2)-Pyrrolin-4-Ones with 3-Isothiocyanato Oxindoles

Arylidene-Delta(2)-pyrrolin-4-ones undergo organocatalyzed double spirocyclization with 3-isothiocianato oxindoles in a domino 1,4/1,2-addition sequence. The products contain three contiguous stereocenters (ee up to 98%, dr up to 99:1, 12 examples). The absolute configuration of the major diastereomer was determined by single crystal X-ray analysis. Along with heterocyclic Michael acceptors based on oxazolone, isoxazolone, thiazolidinone, pyrazolone, and pyrimidinedione, the reported results display the applicability of unsaturated Delta(2)-pyrrolin-4-ones (pyrrolones) for the organocatalyzed construction of 3D-rich pyrrolone-containing heterocycles.

General Synthesis of Secondary Alkylamines by Reductive Alkylation of Nitriles by Aldehydes and Ketones

The development of C-N bond formation reactions is highly desirable due to their importance in biology and chemistry. Recent progress in 3d metal catalysis is indicative of unique selectivity patterns that may permit solving challenges of chemical synthesis. We report here on a catalytic C-N bond formation reaction-the reductive alkylation of nitriles. Aldehydes or ketones and nitriles, all abundantly available and low-cost starting materials, undergo a reductive coupling to form secondary alkylamines and inexpensive hydrogen is used as the reducing agent. The reaction has a very broad scope and many functional groups, including hydrogenation-sensitive examples, are tolerated. We developed a novel cobalt catalyst, which is nanostructured, reusable, and easy to handle. The key seems the earth-abundant metal in combination with a porous support material, N-doped SiC, synthesized from acrylonitrile and a commercially available polycarbosilane.

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 29968-78-3 is helpful to your research. Name: 4-Nitrophenylethylamine hydrochloride.

Characterization of the amino acid adducts of the enedial derivative of teucrin A

The toxicity of germander, a herb used to treat obesity, is attributed to cytochrome P450 activation of the furan ring of its major diterpenoid component (teucrin A) into a reactive metabolite capable of adducting proteins. 1,4-Enedials have been proposed to be the reactive products of metabolism, possibly arising from a rearrangement of putative epoxide intermediates. We synthesized the enedial derivative of teucrin A as well as the enedial derived from a model furan, 3-(4-methoxy-benzyloxymethyl)-furan, by dimethyldioxirane oxidation and characterized the products of their reactions with amino acids and peptides. The reactions of the model enedial, 2-(4-methoxy-benzyloxymethyl)-but-2-enedial,withN-acetyl lysine (NAL) afforded regioisomeric N-alkyl-3-pyrrolin-2-ones, differing in the substitution on the double bond of the heterocyclic ring. Novel products formed in the reactions of the model enedial with N-acetyl cysteine (NAC) and both NAC/NAL uncovered the existence of tautomerization between the enedial and a hydroxyenal, which was manifest by the loss of 4-methoxybenzylalcohol and the incorporation of a second molecule of NAC. The reactions of teucrin A-enedial with NAC and NAL afforded analogues of the products observed with the model enedial, and the existence of the tautomeric equilibrium resulted in epimerization of the proton (H12) adjacent to the former furan ring. This work further illuminates the complex chemical behavior of unsaturated dialdehydes as an important class of toxic metabolites and lays the foundation for studies of the protein targets of teucrin A-enedial.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 272786-64-8, in my other articles.

Energetically significant nitrile center dot center dot center dot nitrile and unconventional C-H center dot center dot center dot pi(nitrile) interactions in pyridine based Ni(II) and Zn(II) coordination compounds: Antiproliferative evaluation and theoretical studies

Two new coordination compounds viz. [Ni(2,6-PDC)(Hdmpz)(H2O)(2)]center dot H2O (1) and [Zn(3-CNpy)(2)Cl-2] (2) (2,6-PDC = 2,6-pyridinedicarboxylate, Hdmpz = 3,5-dimethylpyrazole, 3-CNpy = 3-cyanopyridine) have been synthesized and characterized using elemental analysis, thermogravimetric analysis, electronic, infrared spectroscopy and single crystal X-ray diffraction techniques. Crystal structure analyses reveal the presence of supramolecular assemblies involving interesting dimers with unconventional contacts in the compounds. DFT (Density Functional Theory) calculations on the supramolecular dimers in the crystal structure of 1 reveal that the sum of contributions of anion-pi, pi-pi and other long range interactions due to the approximation of the bulk monomers is energetically significant. Molecular Electrostatic Potential (MEP) surface and Quantum Theory of Atoms in Molecules (QTAIM) analyses on the interesting supramolecular dimers of the crystal structures of 2 reveal the presence of unconventional anion center dot center dot center dot pi contacts involving coordinated chlorido ligands and C-H center dot center dot center dot pi(nitrile) interactions involving the pi-system of the nitrile moiety of 3-cyanopyridine. Remarkably, Atoms in Molecules analysis also confirms the existence of energetically significant unconventional anti-parallel nitrile center dot center dot center dot nitrile interaction in the crystal structure of 2. Cell cytotoxicity of the compounds performed in Dalton’s lymphoma (DL) malignant cancer cell line showed effective potency with negligible cytotoxicity in normal cells (similar to 12%). It is interesting that compound 1has excellent cytotoxic potency with IC50 closer to cisplatin and can bind different biological targets with similar signalling pathways. Structure activity relationship (SAR) analyses of 1 and 2 based on pharmacophore modelling reveal that the molecular features associated with the structures of the compounds play important role in the biological activities.
