Preparation of novel imidazole ligands containing
3-(benzyloxy)pyridinone moiety is described. The Ruiii and
Ruii leader-compounds containing the above-mentioned
ligands were synthesized by coordination of imidazole group.
The stability of the obtained compounds was explored in
buffer solution and in the presence of DMSO, respectively,
and their antiproliferative activity was assessed.

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

Cyanide containing wastewater can cause livestock death and reduce agricultural production and electrochemical reduction of cyanide (CNRR) is a promising way to eliminate its harm and turn waste into valuable products. However, the reaction mechanism and function of electrocatalysts for CNRR have not been fully understood yet. Herein we identify a two-dimensional (2D) conductive copper-organic ...

Colloidal semiconductor nanocrystals have emerged as promising materials for next-generation light-emitting diodes (LEDs) owing to their solution processability, tunable emission wavelengths, narrow emission linewidths, and high photoluminescence quantum yields. Among them, anisotropic nanocrystals, including one-dimensional nanorods (NRs) and two-dimensional nanoplatelets (NPLs), offer additional opportunities for controlling transition dipole moment orientation and light out-coupling efficiency. These ...

The use of hydrophobic deep eutectic solvents (DESs) as extractants for metal ion separation is largely due to the ease of their preparation and the possibility of modifying them depending on the composition of the metal mixture to be separated. However, the most common approach to DES modification involves the replacement of the extractant, while ...

Two voluminous polymer silver(I) salts of perchlorinated dodecoborate clusters, {[(Me2CO)Ag(μ-Me2CO)2Ag(Me2CO)][μ-B12Cl12]}n (1) and {[DMFAg(μ-DMF)2AgDMF][μ-B12Cl12]}n (2) were synthesized. The 35Cl nuclear quadrupole resonance (NQR) spectroscopy supplemented with the X-ray diffraction data was applied for identifying and analyzing noncovalent interactions Cl···X in these salts. Whereas in X-ray diffraction, noncovalent interactions are associated with the presence of the shortened ...

Despite the well-established importance of chalcogen bonding in crystal engineering and supramolecular chemistry, experimental charge density data for TeII-centered chalcogen bonds have remained entirely absent, leaving the electronic nature of these interactions uncharacterized at the level of directly measured electron density. Here, we report the first high-resolution X-ray diffraction (HRXRD) study of TeII-centered chalcogen bonds, ...

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...

We report a high-performance implementation of the resolution-of-the-identity Hartree–Fock method that fully exploits the permutational symmetry of three-center electron repulsion integrals (ERI). The present implementation adopts a hybrid MPI+OpenMP parallelization strategy. Two different algorithmic approaches (with and without the pre-transformation of ERIs) are compared. A custom data layout introduced previously is employed. Designed to efficiently ...

The development of lead sulfide (PbS) quantum dot (QD) photodetectors for short-wave infrared (SWIR) applications has been fundamentally limited by the thermodynamic instability of large PbS QD facets, which leads to aggregation and epitaxial fusion. In this work, robust thermodynamic stabilization was achieved by introducing methylammonium chloride (MACl) in PbS QD surface passivation, as validated ...

Natural R-carvone was converted into chiral 1-aryl-2-methyl-5-isopropyl-cyclohexadienes using a cross-coupling reaction as a key step. These dienes react with RuCl3 to give planar-chiral complexes [(arene)RuCl2]2 in 70–75% yields. Complex [(1-Ph-2-Me-5-iPr-C6H3)RuCl2]2, a chiral analogue of the classical catalyst [(cymene)RuCl2]2, promotes C–H activation of N-methoxy-benzamide and intramolecular insertion of a diazo compound into a C–H bond, but gives products with low ...

Heating tert-butyl-tetraline with [(p-cymene)RuCl2]2 produces the racemic complex [(arene)RuCl2]2, which can be separated into enantiomers by chromatography of its diastereomeric adducts with chiral phosphine ligand. The resolved chiral complex catalyzes C–H activation of N-methoxy-benzamides and their annulation with N-vinyl-pivaloyl amide giving dihydroisoquinolones in 50–80% yields and with 40–80% enantiomeric excess. ...

There is a common assumption that replacement of the classical catalyst based on rare and expensive noble metals by the catalysts based on earth-abundant metals will dramatically reduce the costs of organic synthesis. Herein we demonstrate that it may not be true, mainly because sophisticated organic substrates and modern reagents are often as expensive as ...

Catalytic reductive reactions are essential for laboratory and industrial-scale organic synthesis. However, the nowadays trend is the development of new, progressively more complicated reducing systems, which hinders the application of such highly efficient approaches in practice. Another way to achieve highly active systems is enhancing the activity of the earlier developed catalysts with simple structures. ...

Tris(1-alkylindol-3-yl)methanes were obtained and oxidized into tris(1-alkylindol-3-yl)methylium salts. The resulting salts are more toxic to cultured tumor cells than to non-tumor ones. The cytotoxicity of tris(1-alkylindol-3-yl)methylium salts depends on the length of the substituent at the N atom of the heterocycle, increasing from an N-unsubstituted derivative toward N-butyl- and N-pentyl derivatives. A further increase in ...
