Hydrolysis of Element (White) Phosphorus under the Action of Heterometallic Cubane-Type Cluster {Mo3PdS4}

Reaction of heterometallic cubane-type cluster complexes-[Mo-3{Pd(dba)}S4Cl3(dbbpy)(3)]PF6, [Mo-3{Pd(tu)}S4Cl3(dbbpy)(3)]Cl and [Mo-3{Pd(dba)}S-4(acac)(3)(py)(3)]PF6, where dba-dibenzylideneacetone, dbbpy-4,4 ‘-di-tert-butyl-2,2 ‘-bipyridine, tu-thiourea, acac-acetylacetonate, py-pyridine, with white phosphorus (P-4) in the presence of water leads to the formation of phosphorous acid H3PO3 as the major product. The crucial role of the Pd atom in the cluster core {Mo3PdS4} has been established in the hydrolytic activation of P-4 molecule. The main intermediate of the process, the cluster complex [Mo-3{PdP(OH)(3)}S4Cl3(dbbpy)(3)](+) with coordinated P(OH)(3) molecule and phosphine PH3, have been detected by P-31 NMR spectroscopy in the reaction mixture.

Reduction of dioxygen to water by a Co(N2O2) complex with a 2,2 ‘-bipyridine backbone

We report a Co-based complex for the reduction of O-2 to H2O utilizing decamethylferrocene as chemical reductant and acetic acid as a proton donor in methanol solution. Despite structural similarities to previously reported Co(N2O2) complexes capable of catalytic O-2 reduction, this system shows selectivity for the four-electron/four-proton reduction product, H2O, instead of the two-electron/two-proton reduction product, H2O2. Mechanistic studies show that the overall rate law is analogous to previous examples, suggesting that the key selectivity difference arises in part from increased favorability of protonation at the distal O position of the key intermediate Co(III)-hydroperoxide, instead of the proximal one. Interestingly, no product selectivity dependence is observed with respect to the presence of pyridine, which is proposed to bind trans to O-2 during catalysis.

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. you can also check out more blogs about 2459-09-8. Application In Synthesis of Methyl isonicotinate.

Pyridine-triphenylamine hole transport material for inverted perovskite solar cells

In the light of superior interaction between pyridine unit and perovskite, a facile star-shaped triphenylamine-based hole transport material (HTM) incorporating pyridine core (coded as H-Pyr) is designed and synthesized. A reference HTM with benzene core, coded as H-Ben, is also prepared for a comparative study. The effects of varying core on HTMs are investigated by comparing the photophysical, electrochemical and hole mobility properties. It is found that pyridine core exhibits better conjunction and decreased dihedral angles with triphenylamine side arms than that of benzene, leading to obviously better hole mobility and well-matched work function. The perovskite film prepared on H-Pyr also shows improved crystallization than on H-Ben. Photoluminescence and electrochemical impedance studies indicate improved charge extraction and reduced recombination in the H-Pyr-based perovskite solar cells. Consequently, H-Pyr-based device exhibits higher efficiency than H-Ben-based one. After doping with a Lewis acid, tris(pentafluorophenyl)borane, H-Pyr-based device delivers a champion efficiency of 17.09%, which is much higher compared with 12.14% of the device employing conventional poly(3,4-ethy lenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as HTM. Moreover, the H-Pyr-based device displays good long-term stability that the power conversion efficiency remains over 80% of the initial value after storage in ambient (relative humidity = 50 +/- 5%) for 20 days.

Hydro-upgrading of light cycle oil-synthesis of NiMo/SiO2-Al2O3-TiO2 porous catalyst

The demand for transportation diesel fuels has been increasing in most countries for the last decade. As is one of the primary sources for diesel distillates, light cycle oil (LCO), having the advantages of inheriting similar density and boiling point range to diesel fuels, but high contents of aromatics, sulfur, and nitrogen, needs to be upgraded before being utilized. This work reports a trinary porous SiO2-Al2O3-TiO2 (SAT) synthesized by sol-gel method and used as the NiMo catalyst support for the LCO hydro-upgrading. NiMo/Al2O3-zeolite (AZ) was used as a reference to evaluate the performances of the NiMo/SAT. The catalysts were characterized by XRD, BET, Pyridine-FTIR, and TEM; and evaluated in a 20-mL fixed-bed microreactor using a Fluid Catalytic Cracking LCO as feedstock. It was found that the SAT support possessed a high surface area, high pore volume, and good acid properties. The NiMo/SAT catalyst exhibited even better hydrodesulfurization, hydrodenitrogenation, and hydrodearomatization performances than NiMo/AZ when the reaction was performed at 375 degrees C and 1100 psi. Compared with the zeolite addition catalyst, the SAT catalyst has the advantages of simple synthesis procedures and low input cost.

Synthesis, physicochemical and vibrational spectral properties of 2-pyridone and 2-aminopyridine derivatives: An experimental and theoretical study

A convenient and efficient one-pot three-component reaction of acetyl acetone, malononitrile and ammonium acetate was investigated for the synthesis of 3-cyano-4,6-dimethyl-2-pyridone (PI) and 2-amino-3-cyano-4,6-dimethylpyridine (PII). The products were achieved with high purity, high yields and short reaction time. The yields of the two products depend on the concentration of ammonium acetate, reaction time and the solvent used. The structures of the isolated products were confirmed by elemental analysis and spectral data, supported by quantum chemical (MP2) calculations, both in gas phase and solvents (water and ethanol), that were also employed to track the reaction mechanisms and model vibrational spectral properties for final characterization and interpretation of spectral data. A remarkable matching between theoretical predictions and experiments was attained both for the geometrical parameters, as compared to X-Ray data available in the literature, and for vibrational frequencies, leading to a correlation coefficient (R-2) of 0.99. Molecular docking was further studied to predict the docking binding energy of the synthesized compounds with the target proteins. (C) 2020 Elsevier B.V. All rights reserved.

Antiglycation and antioxidant potential of novel imidazo[4,5-b]pyridine benzohydrazones

A series consisting of 30 novel imidazo[4,5-b]pyridine benzohydrazones have been synthesized and evaluated for their antiglycation activity as well as their antioxidative potential. The synthetic part involves a 3-step reaction in which a pyridine diamine was being converted into a imidazo[4,5-b]pyridine, which was then subjected through another reaction to yield benzohydrazide. Subsequently, the attained benzohydrazide of imidazo[4,5-b]pyridine was used to synthesize the target molecules after treating them with the appropriate benzohydrazone derivatives. The derivatives were evaluated for the antiglycation and antioxidant activities. Result obtained showed that di and trihydroxy substituted compounds showed good activity with compound 25 (140.16 +/- 0.36 mu M) having the most potent antiglycation activity, which is twice lower than Rutin. The results also showed certain correlation between antiglycation activities with DPPH radical scavenging model as well as FRAP which indicated the participation of antioxidative effect in inhibiting glycation activity.

Boosting levulinic acid hydrogenation to value-added 1,4-pentanediol using microwave-assisted gold catalysis

Microwave (MW) -assisted levulinic acid (LA) hydrogenation has been performed over two gold catalysts (commercial 1 wt% Au/TiO2 by AUROlite (TM) and 2.5 wt% Au/ZrO2, prepared using deposition-precipitation). MW-assisted LA hydrogenation was carried out in water and in solvent-free conditions via (i) H-transfer and (ii) molecular H-2. Au/TiO2 promoted complete LA conversion and the further reduction of the produced GVL to 1,4-pentanediol (1,4-PDO) in the presence of 50 bar H-2 at 150 degrees C (4-hour reaction). Interestingly, selectivity to 1,4-PDO was complete at 200 degrees C. Extended characterisation highlighted the cooperative role played by the gold nanoparticles and the support, onto which activated hydrogen atoms spillover to react with LA. This results in the remarkable activity of Au/TiO2. Both catalysts showed structural and morphological stability under reaction conditions. It was possible to reactivate the Au/TiO2 catalyst by MW-assisted oxidation, paving the way for catalyst recycling directly inside the MW reactor. (C) 2019 Elsevier Inc. All rights reserved.

An Iron Pyridyl-Carbene Electrocatalyst for Low Overpotential CO2 Reduction to CO

Electrocatalysts for CO2 reduction based on first-row transition metal ions have attracted attention as abundant and affordable candidates for energy conversion applications. Yet very few molecular iron electrocatalysts exhibit high selectivity for CO. Iron complexes supported by a redox-active 2,2′:6′,2 ”-terpyridine (tpy) ligand and a strong trans effect pyridyl-N-heterocyclic carbene ligand (1-methylbenzimidazol-2-ylidene-3-(2-pyridine)) were synthesized and found to catalyze the selective electroreduction of CO2 to CO at very low overpotentials. Mechanistic studies using electrochemical and computational methods provided insights into the nature of catalytic intermediates that guided the development of continuous CO2 flow conditions that improved the performance, producing CO with >95% Faradaic efficiency at an overpotential of only 150 mV. The studies reveal general design principles for nonheme iron electrocatalysts, including the importance of lability and geometric isomerization, that can serve to guide future developments in the design of affordable and efficient catalysts for CO2 electroreduction.
