Methyl vinyl glycolate as a diverse platform molecule

Methyl vinyl glycolate (methyl 2-hydroxybut-3-enoate, MVG) is available by zeolite catalyzed degradation of mono- and disaccharides and has the potential to become a renewable platform molecule for commercially relevant catalytic transformations. This is further illustrated here by the development of four reactions to afford industrially promising structures. Catalytic homo metathesis of MVG using Grubbs-type catalysts affords the crystalline dimer dimethyl (E)-2,5-dihydroxyhex-3-enedioate in excellent yield and with meso stereochemical configuration. Cross metathesis reactions between MVG and various long-chain terminal olefins give unsaturated alpha-hydroxy fatty acid methyl esters in good yields. [3,3]-Sigmatropic rearrangements of MVG also proceed in good yields to give unsaturated adipic acid derivatives. Finally, rearrangement of the allylic acetate of MVG proceeds in acceptable yield to afford methyl 4-acetoxycrotonate.

Luminescent Cyclometalated Platinum Complexes with pi-Bonded Catecholate Organometallic Ligands

A series of cyclometalated platinum(II) complexes of the type [(ppy)Pt(LM)]n+ (n = 0, 1) with pi-bonded catecholates acting as organometallic ligands (LM) have been prepared and characterized by analytical techniques. In addition, the structures of two complexes of the series were determined by single-crystal X-ray diffraction. The packing shows the formation of a 1D supramolecular assembly generated by dPt-piCp* interactions among individual units. All complexes are luminescent in the solid state and in solution media. The results of photophysics have been rationalized by means of density functional theory (DFT) and time-dependent DFT investigations.

Synthesis and Evaluation of Sterically Demanding Ruthenium Dithiolate Catalysts for Stereoretentive Olefin Metathesis

Dithiolate ligands have recently been used in ruthenium-catalyzed olefin metathesis and have provided access to a kinetically E selective pathway through stereoretentive olefin metathesis. The typical dithiolate used is relatively simple with low steric demands imparted on the catalyst. We have developed a synthetic route that allows access to sterically demanding dithiolate ligands. The catalysts generated provided a pathway to study the intricate structure-activity relationships in olefin metathesis. It was found that DFT calculations can predict the ligand arrangement around the ruthenium center with remarkable accuracy. These dithiolate catalysts proved resistant to ligand isomerization and were stable even under forcing conditions. Additionally, catalyst initiation and olefin metathesis studies delivered a better understanding to the interplay between dithiolate ligand structure and catalyst activity and selectivity.

Chemoselective cross-metathesis reaction between electron-deficient 1,3-dienes and olefins

Chemoselective cross-metathesis reactions between methyl sorbate or 1,3-dienic amides and various olefins in the presence of the Grubbs-Hoveyda catalyst have been investigated. Cross-metathesis reactions turned out to be more chemoselective with 1,3-dienic amides than with 1,3-dienic esters.

The role of cations of the electrolyte for the pseudocapacitive behavior of metal oxide electrodes, MnO2 and RuO2

The energy storage process for amorphous hydrated manganese dioxide (MnO2) is suggested as fast faradaic reactions occurring at the solid electrode surface with the reduction from Mn4+ to Mn3+. In order to understand the role of cations of the electrolyte for the MnO 2 electrode as a pseudocapacitor in aqueous KCl solution, we monitored the change of the capacitance by varying the concentration of the KCl electrolyte, the cation of the electrolyte, the pH of the solution, and the solvent. The charge storage for the metal oxide electrode such as MnO 2 is concluded to involve a fast redox reaction through both potassium ion exchange, MnO2 + delta K+ + delta e – ? MnO2-delta(OK)delta and proton exchange, MnO2 + delta H+ + delta e- ? MnO2-delta(OH)delta dependent upon the availability of cations in the electrolyte. The contribution of proton to the pseudocapacitive process is not negligible in aqueous solution.

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 10049-08-8 is helpful to your research., Related Products of 10049-08-8

Areneruthenium(II) 4-acyl-5-pyrazolonate derivatives: Coordination chemistry, redox properties, and reactivity

Areneruthenium(II) molecular complexes of the formula [Ru(arene)(Q)Cl], containing diverse 4-acyl-5-pyrazolonate ligands Q with arene = cymene or benzene, have been synthesized by the interaction of HQ and [Ru(arene)Cl-(mu- Cl)]2 dimers in methanol in the presence of sodium methoxide. The dinuclear compound [{Ru(cymene)Cl}2Q4Q] (H2Q4Q = bis(4-(1-phenyl-3-methyl-5-pyrazolone)dioxohexane), existing in the ARuSRu (meso form), has been prepared similarly. [Ru(cymene)(Q)Cl] reacts with sodium azide in acetone, affording [Ru(cymene)(Q)N3] derivatives, where Cl – has been replaced by N3-. The reactivity of [Ru(cymene)(Q)Cl] has also been explored toward monodentate donor ligands L (L = triphenylphosphine, 1-methylimidazole, or 1-methyl-2-mercaptoimidazole) and exo-bidentate ditopic donor ligands L-L (L-L = 4,4?-bipyridine or bis(diphenylphosphino)propane) in the presence of silver salts AgX (X = SO 3CF3 or ClO4), new ionic mononuclear complexes of the formula [Ru(cymene)(Q)L]X, and ionic dinuclear complexes of the formula [{Ru(cymene)(Q)}2L-L]X2 being obtained. The solid-state structures of a number of complexes were confirmed by X-ray crystallographic studies. Their redox properties have been investigated by cyclic voltammetry and controlled potential electrolysis, which, on the basis of their measured RuII/III reversible oxidation potentials, have allowed the ordering of the bidentate acylpyrazolonate ligands according to their electron-donor character and are indicative of a small dependence of the HOMO energy upon the change of the monodentate ligand. This is accounted for by DFT calculations, which show a relevant contribution of acylpyrazolonate ligand orbitals to the HOMOs, whereas that from the monodentate ligand is minor.

Catalytic surfactants for ring-opening metathesis polymerization and ring-closing metathesis in non-degassed micellar solutions

Metathesis catalysts bearing long alkyl chains and analogous to Hoveyda’s catalyst have been synthesized. Their surface-active properties have been characterized by formation of Langmuir films at the air-water interface. They have been dispersed in micelles formed in non-degassed water and been used in polymerization of a hydrophilic monomer. These surfactants are therefore the first inisurf molecules for metathesis polymerization that are air-stable. Their ability to catalyze ring-closing metathesis in water has also been evaluated.
