Theoretical insight into the role of nitrogen in the formic acid decomposition over Pt-13/N-GNS

Catalytic decomposition of formic acid is regarded as one of the most promising hydrogen source conversion technologies. Nitrogen doped carbon supported metal catalyst emerges in recent years and delivers excellent performance in formic acid hydrogenation. However, there is not a well-recognized explanation about the real role of the nitrogen dopant in carbon support. In this work, density functional theory-based calculations were used to individually study the ligand effect and catalytic effect from the nitrogen dopant. Ligand effect mainly tunes the electronic properties of metal active center by shifting d-band center far away from Fermi level. The result unravels that C-H scission path is more favorable compared with O-H scission path. Catalytic effect is originated from the lower electrostatic potential of nitrogen active site compared with platinum, making N site an efficient capturer for hydrogen atom. Though activation energy for cleaving O-H bond is higher than C-H bond, nitrogen site can efficiently cleave the O-H bond. Microkinetic simulations are performed to obtain the best nitrogen doping concentration in the carbon support. It implies that the optimal nitrogen concentration is a function of temperature, according to the optimized curve. This work will improve the understanding of mechanism of formic acid decomposition and provide new method in modifying metal/carbon support catalysts.

Copper-Catalyzed Oxidative Cleavage of the C-C Bonds of beta-Alkoxy Alcohols and beta-1 Compounds

Copper-catalyzed aerobic oxidation conditions were employed to promote the C-C bond cleavage of beta-alkoxy alcohols and beta-1 compounds (lignin model compounds). Besides these compounds, various 1,2 and 1,3-diols were successfully converted to aldehydes. We propose the Cu(I)-catalyzed mechanism explaining the C-C cleavage of these 1,2 and 1,3-dihydroxy compounds and beta-alkory alcohols based on XPS data. Although our reaction conditions do not include large excess of bases and elaborated ligand-modified catalysts, copper salts with/without Me-TBD show good catalytic activities for C-C bond cleavage of various lignin model compounds.

BIPHASIC HYDROGENATION OF EUGENOL WITH RUTHENIUM AND RHODIUM NANOPARTICLES STABILIZED IN IONIC LIQUIDS

The purpose of this study was to evaluate on the catalytic activity nanostructured systems of ruthenium and rhodium stabilized in ionic liquids derived from imidazole: IL1 = butylmethyllimidazole tetrafluoroborate [BMIM][BF4] and IL2 = butylmethylimidazole hexafluorophosphate [BMIM][PF6] in the biphasic hydrogenation of eugenol under mild reaction conditions T= 80 degrees C, P= 100psi during 4 hours. The metallic nanoparticles (NPs-M) were synthesized using the ligand hydrogenation displacement reaction for the ruthenium III tris(acetylacetonate), [Ru(acac)(3)], and bis-mu-cloro-di(1,5-ciclooctadieno) dirhodium(I), [Rh(COD)Cl](2), showing a mean particle size between (2.0 +/-_0.2) nm and (4.0 +/- 0.2) nm. The nanostructured systems Rh/IL2, Ru/IL2 and Ru/IL1 show similar activities and different from the Rh/IL1 system. On the other hand, the systems stabilized in the IL1 were more selective towards the formation of the 2-methoxy-4-propylphenol than the systems stabilized in the IL2. Nevertheless, in general, the catalysts were good for hydrogenating eugenol, resulting in Rh/IL1 nanoparticles less reactive than Rh/IL2, Ru/IL1 and Ru/IL2.

Single-Molecule Activation and Quantification of Mechanically Triggered Palladium-Carbene Bond Dissociation

Metal-complexed N-heterocyclic carbene (NHC) mechanophores are latent reactants and catalysts for a range of mechanically driven chemical responses, but mechanochemical scission of the metal-NHC bond has not been experimentally characterized. Here we report the single-molecule force spectroscopy of ligand dissociation from a pincer NHC-pyridine-NHC Pd(II) complex. The force-coupled rate constant for ligand dissociation reaches 50 s(-1) at forces of approximately 930 pN. Experimental and computational observations support a dissociative, rather than associative, mechanism of ligand displacement, with rate-limiting scission of the Pd-NHC bond followed by rapid dissociation of the pyridine moiety from Pd.

Identification of Single-Atom Ni Site Active toward Electrochemical CO2 Conversion to CO

Electrocatalytic conversion of CO2 into value-added products offers a new paradigm for a sustainable carbon economy. For active CO2 electrolysis, the single-atom Ni catalyst has been proposed as promising from experiments, but an idealized Ni-N-4 site shows an unfavorable energetics from theory, leading to many debates on the chemical nature responsible for high activity. To resolve this conundrum, here we investigated CO2 electrolysis of Ni sites with well-defined coordination, tetraphenylporphyrin (N-4-TPP) and 21-oxatetraphenylporphyrin (N3O-TPP). Advanced spectroscopic and computational studies revealed that the broken ligand-field symmetry is the key for active CO2 electrolysis, which subordinates an increase in the Ni redox potential yielding Ni-I. Along with their importance in activity, ligand-field symmetry and strength are directly related to the stability of the Ni center. This suggests the next quest for an activity-stability map in the domain of ligand-field strength, toward a rational ligand-field engineering of single-atom Ni catalysts for efficient CO2 electrolysis.

Three-Coordinate Zinc Methyl Complexes with Sterically Demanding Formazanate Ligands

A series of heteroleptic three-coordinate mono(formazanate)zinc methyl complexes were synthesized, and the influence of the ligand on the structure as well as redox and optical properties of these complexes was investigated. The heteroleptic mono(formazanate)zinc methyl complexes were found to show ligand redistribution in solution, reminiscent of the Schlenk equilibrium, to generate an equilibrium mixture containing the corresponding homoleptic complexes as well. Monitoring the approach to equilibrium by NMR spectroscopy in benzene-d(6) allowed determination of the forward and backward rate constants. A correlation was found between the steric environment around the zinc center and equilibrium concentration of (formazanate)zinc methyl compounds, whereas the kinetics for approach to equilibrium are also dependent on the electronic properties.

Chromium-Catalyzed Selective Dimerization/Hydroboration of Allenes to Access Boryl-Functionalized Skipped (E,Z)-Dienes

A chromium-catalyzed dimerization/hydroboration of allenes is developed to access synthetically versatile boryl-functionalized skipped dienes with a catalyst generated in situ from CrCl2 and a pyridine-2,6-diimine ligand (PDI)-P-mes. A variety of allenes reacted with pinacolborane (HBpin) to afford the corresponding boryl-functionalized (E,Z)-1,4-dienes in high yields and with excellent selectivity. Electron paramagnetic resonance (EPR) spectroscopic studies suggest that this chromium-catalyzed reaction probably proceeds through a chromium(I) hydride intermediate.

Nano-size bimetallic ternary hydrogenation catalysts based on nickel and copper complexes

The turnover frequencies of multicomponent ternary catalytic systems formed on the basis of Ni(acac)(2) and Cu(acac)(2) with LiAlH4 at T = 30 degrees C and P-H2 = 2 atm in styrene hydrogenation were determined. It was shown that, at other things being equal, catalytic activity is defined by the order of mixing of the components at the catalyst formation stage. Namely, three particular cases are considered: sequential reduction of Ni(acac)(2) and Cu(acac)(2) by LiAlH4 (first Ni(acac)(2), then Cu(acac)(2) and vice versa) and simultaneous reduction of Ni(acac)(2) and Cu(acac)(2) with LiAlH4. It has been established that nano-sized structures of the core@shell type act as carriers of catalytic activity. The nano-sized structures are stabilized by the ligand shell, which contain Li(acac) as well as AlH4- and AlH63–anions. The model of the catalytically active (in styrene hydrogenation) nanoparticle formed by sequential reduction of Cu(acac)(2) with LiAlH4 and Ni(acac)(2) is presented. (C) 2020 Elsevier B.V.

Synthesis of 4-amino-5-allenylisoxazoles via gold(i)-catalysed propargyl aza-Claisen rearrangement

Propargyl aza-Claisen rearrangement of 4-propargylaminoisoxazoles 1 proceeded in the presence of cationic gold(i) catalysts to give 4-amino-5-allenylisoxazoles 2 in good to high yields. The silyl group at the terminal alkyne and a cationic gold(i) catalyst bearing a sterically bulky ligand are essential for the generation of isolable allene intermediates. The N-protection of the generated 4-amino-5-allenylisoxazoles 2 allowed the isolation of 5-allenylisoxazoles 4 that have never been synthesized. N-Propargyl aniline 5 was successfully converted to the corresponding ortho-allenyl aniline 6 under the current reaction conditions.

The mechanism of Metal-H2O2 complex immobilized on MCM-48 and enhanced electron transfer for effective peroxone ozonation of sulfamethazine

In the peroxone process (O-3/H2O2), (OH)-O-center dot yield ratio with respect to O-3 consumption was low due to the competition experiments. Singular effectiveness of Co-Ce as a supporting ligand in the interface of ozone-H2O2-catalysts and related complexes formed on catalysts enhanced the electron transfer between ozone chain reaction and various chemical state of Ce/Co. A computationally determined stereochemical structure corroborated that the Co-Ce synergistic effect led to the region around Co atom (electron donor) with low Gibbs free energy to form (OH)-O-center dot. Meanwhile, reactive oxygen species (ROSs) were tend to attack the sites with very negative natural population charge or high frontier electron density (FED) values of sulfamethazine (SMT) by LC-MS/MS and density functional theory (DFT) calculations. Benefiting from the unique superoxide complexes and synergetic effect of Co-Ce, the Co10Ce10@MCM-48 catalysts showed superior performance of SMT mineralization (64.1 %, 120 min), which resolved the low-efficient ROSs generation in bare peroxone reaction.
