Four new coordination compounds of nickel (II) with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine were synthesized; their composition and structure were confirmed with IR-spectroscopy and elemental analysis. The structures of products 13 and 15 were unambiguously established in an X-ray diffraction study. Compounds 13 and 15 crystallize in the orthorhombic space groups Pna2(1) and P2(1)2(1)2(1) correspondingly and represent a monomeric octahedral nickel complexes, that are typical for tridentate scorpion-type ligands. New method for immobilization of nickel complexes with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine on silica gel modified with aminopropyl groups was proposed. The EXAFS/XANES analysis indicated that Ni atom in the supported complexes adopt almost octahedral geometry, being partly surrounded by nitrogen atoms from organic ligand and partly grafted to silica surface through silanol groups, with Br- in outer coordination sphere. Both the original and the supported complexes, when activated with Et2AlCl or Et3Al2Cl3, catalyze ethylene oligomerization with the predominant formation of butene isomers. Generally, the immobilized complexes show higher activity and better selectivity towards 1-butene formation.

Self-healing materials can partially or completely heal the damage done to them, and it is expected that their original function will be thereby restored. Herein, we report a novel self-healing polyvinyl (Sh-PV) containing functional polymer that reacts to thermal and ultraviolet (UV) energy. The structure of Sh-PV was characterized by fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (H-1 NMR). In addition, aluminum oxide (Al2O3) inorganic nanoparticles (NPs) were added and hybridized to improve their poor self-healing efficiency and surface hardness of the coated thin film. Mechanical nanoscratch testing and scanning probe microscopy (SPM) imaging of surface using a nanoindenter were performed to investigate the healing ability of self-healing thin films. The organic-inorganic hybrid self-healing polymer thin film exhibited a 10 % improvement in surface hardness as well as 100 % healing against nanoscale damage compared to virgin self-healing polymers. Here, we discuss and evaluate the optimized method and mechanism of the self-healing system based on the results of self-healing materials and physical recovery methods for healing surface damage.

Mango waste is one of the most promising sources of renewable energy, especially as this waste represents 40% of the weight of mango fruit and contains a large amount of fat and cellulose that can contribute to converting it into energy products using pyrolysis and gasification process. Within this context, this research aims to investigate pyrolysis and gasification kinetic behavior of mango seed shells (MSS) using TG-FTIR-GCeMS system. The experiments were started by analyzing the composition of different types of Egyptian MSS, then their pyrolysis characteristics and chemical decomposition in N-2 and CO2 atmospheres using TG-FTIR system upto 900 degrees C at heating rates in the range 5-30 degrees C/min were studied. The GC/MS system was employed to determine the formulated volatile products at the maximum decomposition temperatures (343-346 degrees C for N-2 and 334-340 degrees C for CO2). Afterwards, the model-free/model-fitting methods, including KissingereAkahiraeSunose, FlynneWalleOzawa, and Friedman, and Distributed Activation Energy Model (DAEM) were used to estimate the kinetic parameters of pyrolysis of MSS in both atmospheres. Finally, chars derived from pyrolysis were exposed to CO2 gasification process, followed by studying of their kinetic behavior in the modified random pore model (MRPM). The results showed that the decomposed MSS were saturated with a huge amount of volatile products, particularly Carbon dioxide and Ethylene oxide (99.27% in CO2 and 20.77% in N-2), while Acetic acid, Propanone, Hexasiloxane, Glycidol, Ethanedial, Ethylene oxide, Formic acid, etc. were the main compounds in case of N-2. Meanwhile, the studies of kinetics of pyrolysis showed that the average activation energies were estimated in the range of 231-262 kJ/mol (N-2) and 259-333 kJ/mol (CO2). Based on that, pyrolysis and gasification can be adapted as promising technologies to valorize MSS and utilize them as a new sustainable source for renewable energy. (C) 2021 Elsevier Ltd.

In the process of research and development of new drugs, in silico analyzes are widely used. They address the pharmacokinetics of the molecules in study and can predict the binding mode and affinity, using a docking software. This approach can optimize the development of new drugs, reducing costs, time, and resources. In this study, a library of 300 pyrazole-chalcone derivatives were designed, the in silico ADMET (absorption, distribution, metabolism, excretion, and toxicity) properties were evaluated, and a structure-based virtual screening was performed using AutoDock Vina. The docking results exhibited that the derivatives binding mode at the COX-2 active site is similar to celecoxib, the reference drug, and presented similar binding energy. Six compounds were synthetized and tested for in vitro inhibition of the COX-1 and COX-2 isoenzymes and the selectivity index (SI) was calculated. The compound 2a11 showed the best activity for COX-2 (IC50COX-2=0.73M) whereas the control, celecoxib, resulted IC50COX-2=0.88M. All the other compounds synthetized presented better potency for COX-2 inhibition than the control. Compound 2a23 exhibited the higher SI, of 280.17 (IC50COX-1=210.13M/ IC50COX-2=0.75M), while celecoxib was 246.88 (IC50COX-1=217.26M/ IC50COX-2=0.88M). These results corroborate with a possible anti-inflammatory activity and COX-2 selectivity of the new compounds synthetized.

A visible-light photoredox catalyzed C-N coupling of quinoxaline-2(1H)-ones with azoles in the absence of external photosensitizer has been developed. The protocol employs commercially available pyrazoles and triazoles as amination reagents and shows wide substrate scope, providing the corresponding C3-position amination products in good yields and high regioselectivity under ambient conditions. Investigations indicate that the starting materials and products can act as photosensitizers avoiding use of additional photocatalyst in an autocatalytic manner. In addition,(1)O(2)coexists with O(2)(.-)from molecular oxygen (O-3(2)) via an energy transfer (ET) and single electron transfer (SET) process during the reaction.

Dearomatization of indole derivatives offers a straightforward approach to access diverse indolines. To date, the corresponding dearomative transformations involving electron-deficient indoles are limited. Herein, we report a one-electron strategy for dearomatization of electron-deficient indoles via a photoredox-catalyzed hydroalkylation employing commercially available glycine derivatives as the hydrofunctionalization reagents. Followed by DBU-mediated lactamization, structurally appealing lactam-fused indolines are obtained in good to excellent yields with exclusive selectivity.

The title compound, [Cu-2(C5H7N2)(C4H10NO2)Cl-2(C5H8N2)], is a pyrazolate aminoalcohol complex which contains two dimethylpyrazole molecules in monodentate and bidentate-bridged coordination modes and a monodeprotonated diethanolamine molecule. Both copper atoms are involved in the formation of non-planar five-membered chelate rings. One Cu atom is in a distorted tetrahedral environment formed by the pyridine nitrogen atom of the protonated dimethylpyrazole molecule, the N atom of the deprotonated bridged dimethylpyrazole, the Cl atom and the bridged O atom of the monodeprotonated diethanolamine. The second Cu atom has an intermediate environment between trigonal bipyramidal and square pyramidal, formed by the N atom of the deprotonated bridged dimethylpyrazole, the Cl atom and the N atom of the aminoalcohol, and two O atoms of the deprotonated and protonated OH groups. In the crystal, N-H center dot center dot center dot Cl hydrogen bonds link the molecules into antisymmetric chains running along the a-axis direction. Adjacent chains are connected by O-H center dot center dot center dot O hydrogen bonds involving the hydroxyl group as donor.

Electrocatalytic hydrogenation is a particularly attractive approach for converting the most unstable compounds in biogenic feedstocks at ambient conditions without external H-2. Here, we synthesized a variety of carbon-supported transition metal catalysts and characterized their activity for the electrocatalytic hydrogenation of a series of model compounds and pyrolysis bio-oil. Carbonyl compounds, especially aromatic aldehydes, such as furfural and benzaldehyde, are particularly inclined to hydrogenation driven by an applied current. This was verified with pure solutions of the model compounds and with pyrolysis bio-oil, where we achieved stable and steady continuous operation on Pd. When optimal catalyst composition was chosen, the conversion of benzaldehyde shifted from alcohol production (e.g., on Pd and Cu) to dimerization (e.g., on Co, Ni, and Zn). Pd and Cu were shown to offer the best compromise between reaction rates and efficiency although, in general, base metals offer similar conversions but better efficiencies than noble metals. Thus, the present work offers foundational results and guidelines for choosing the optimal metal catalyst and the applied potential for processing organic feedstocks as a function of its composition.

Two penta-coordinate complexes of the general formula [Co(L-n)(NCS)]ClO4, where L-1= {bis[(3,5-dimethyl-1H-pyrazol-1-yl)ethyl]-[(3,4-dimethoxypyridin-2-yl)methyl]}amine and L-2= {bis[(3,5-dimethyl-1H-pyrazol-1-yl)ethyl]-[(4-methoxy-3,5-dimethylpyridin-2-yl)methyl]}amine, have been synthesized and thoroughly characterized. Each of the cobalt(ii) atoms is penta-coordinated in the {CoN5} donor set with a distorted square-pyramidal geometry in [Co(L-1)(NCS)]ClO4 center dot MeOH (1), while the vicinity of the central atom can be described as a distorted trigonal-bipyramidal geometry in [Co(L-2)(NCS)]ClO4(2) as revealed using the SHAPE analysis. Differences in interatomic parameters among the cobalt(ii) and donor atoms in 1 and 2 have definite impact on the magnetic features of both compounds. The complexes show an easy-axis magnetic anisotropy (D = -38.5 cm(-1) for 1 and D= -8.5 for 2), and both complexes reveal a large rhombicity with E/D = 0.21 for 1 and E/D = 0.29 for 2. The ZFS parameters (g, D and E) were also calculated using CASSCF/NEVPT2 methods and they are in good agreement with those determined from experimental data. A frequency dependent out-of-phase susceptibility has been observed in external magnetic field (B-dc= 0.1 T) revealing the following parameters of slow relaxation of magnetization for 1: energy of the spin reversal barrier, U-eff = 16.0 cm(-1)(U-eff/kB = 23.0 K) and the relaxation time, tau(0)= 1.28 x 10(-6)s. In the case of complex 2, no maxima of frequency dependent out-of-phase susceptibility have been observed and thus, the value of U-eff= 17 cm(-1) has been estimated using the expression U-eff = vertical bar D vertical bar x (S-2- 1/4). It has been demonstrated that the degree of substitution and the type of substituents on the pyridyl moieties of the tripodal ligands (L-1 and L-2) used in these penta-coordinate cobalt(ii) complexes have significant impact on structural and magnetic features.
