A heptafluorobutyric acid-induced cross-dehydrogenative coupling reaction of arylamines with 1,2,4-triazines has been described. This metal-free protocol enables regioselective para-C–H hetarylation of diverse arylamines including well-known fluorophore scaffolds, such as triphenylamine, carbazole, and phenothiazine, with easily accessible 1,2,4-triazines under mild conditions. This approach has potential for drug development and material design. ...

Three new Hg(II) bromide complexes, HgBr2L (1–3) (L1 = N′-(pyridin-2-ylmethylene)isonicotinohydrazide, L2 = N′-(1-(pyridin-2-yl)ethylidene)isonicotinohydrazide, L3 = N′-(phenyl(pyridin-2-yl)methylene)isonicotinohydrazide), have been synthesized in good yields and thoroughly characterized. Single-crystal X-ray diffraction analyses unveil that complexes 1 and 3 are mononuclear, while complex 2 is dinuclear. All complexes further assemble into one-dimensional supramolecular chains mediated by N–H···N hydrogen bonds, which are reinforced by π···π stacking and Br···Br halogen interactions. Systematic variation ...

Two new supramolecular halometalate hybrid complexes, (H2bpen){[MCl5](I2)} (M = Sb(III) (1) and Bi(III) (2); bpen – 1,2-Bis(4-pyridyl)ethylene, have been prepared. Despite very close similarity of the nature of cations, they reveal significant structural difference from the (H2bpe){[MCl5](I2)} (bpe – 1,2-bis(4-pyridil)ethane) reported earlier. We discuss these features, along with thermal stability, optical properties as well as Raman spectra ...

The rational design of coinage metal nanocarriers requires a mechanistic understanding of metal-drug binding and predictive descriptors that translate molecular interactions into design rules. Using DFT (B3LYP-D3BJ/def2-TZVP, SMD water), we systematically investigated the binding of 5-fluorouracil (5-FU) and levodopa (l-DOPA) to neutral and cationic homo- and heteronuclear dimers of Au, Ag, and Cu (Au2, Ag2, ...

Rational design of gold-based nanocarriers for neurotherapeutics requires atomic-scale understanding of drug-material interactions. Density functional theory calculations were performed to investigate levodopa (L-DOPA) adsorption on small gold clusters (Au2–Au4) with cationic, neutral, and anionic charges, with additional validation on a larger Au10 cluster using multiple low-energy isomers. Binding free energies (ΔGbind), charge transfer, and electronic descriptors ...

Most of scientific research involves the use of computational tools, while researchers have low IT competences. The efficiency of working with computational modules for scientific research can be significantly increased by guaranteeing reproducibility, interactivity, and reusability of producing artifacts. This can be achieved by using a reactive environment with a standardized set of UI controls, ...

The article examines inter-state attempts to enhance industrial development in the Council for Mutual Economic Assistance (Comecon, or CMEA) between the 1950s and 1980s. It studies how state socialism aimed to build a network of economic and research institutions to transform the bloc into a technological leader during the Cold War. Building upon previously unpublished ...

Over the past few decades, quantitative methods of evaluating scientific work, including the citation index of research publications, have been finding expanding applications. The citation index underlies not only the evaluation of the efficiency of individual scientists but also the rating of scientific editions. The authors share their experience in bibliometric research based on the ...

The concept of using redox-active ligands, which has become extremely widespread in organometallic chemistry, is often considered from 'their effect on the metal center properties' point of view and 'how to modify the ligands'. In this paper, we present the reverse side of this effective approach - a dramatic change of redox properties of ligands ...
