Between Diplomacy and Intrigue: Informal Aspects of Franco-Russian Relations in 1870s-1880s

The article deals with the informal aspects of the preparation of the Franco-Russian rapprochement in the 1870s–1880s, which later resulted in the military alliance concluded in 1894 between France and Russia. The authors consider the process of formation and strengthening of many informal networks that contributed to the emergence of a favorable basis for concluding an alliance between countries. Particular attention in the article is paid to the specifics of the activities of the salons of E.E. Trubetskoy and J. Adam, which became a platform for establishing personal contacts between persons aimed at the alliance of France and Russia. The authors dwell on a detailed analysis of the formed ties between French and Russian intellectuals, the point of contact of which was the formation of “cultural pan-Slavism”. In this regard, the activity of the editor of “Moskovskie Vedomosti” M.N. Katkov is highlighted and those vast networks and political influence that he managed to establish is identified. The authors come to the conclusion that the Franco-Russian rapprochement in the 1870s-1880s actively developed on the wave of the idea of revanchism in France and the popularity of pan-Slavism, as well as through the contacts and initiatives of individuals connected by a network of informal ties with the government circles of both states

© 2017, Pleiades Publishing, Ltd. A method of synthesis of organophosphorus analog of ethylenediaminetetraacetic acid (a common complexon), N,N,N′,N′-tetrakis(O-butylhydroxyphosphorylmethyl)-1,2-diaminoethane, has been elaborated. The product structure has been elucidated by means of NMR spectroscopy and X-ray diffraction analysis. Constants of the acid dissociation and the stability of the 1 : 1 complexes with Co(II), Ni(II), and Cu(II) ions have been determined

Synthesis and membrane-transport properties of phosphorylated diamines, azapodands and their derivatives

© 2018, © 2018 Taylor & Francis Group, LLC. Membrane–transport properties of synthesized phosphorylated azapodands of a series of metals of I groups were studied. The investigation of the processes of passive membrane ion transport showed the phosphorylated azapodands 2 and 3 were the most selective with respect to the lithium ion. A monophosphorylated podand, which contain a heterocyclic nitrogen atom 8-(1-diamylphosphoryl-3,5-dioxapentane) quinoline 7 was synthesized. The molecular structure of the complex of a podande 7 with a copper ion was determined by the method of X-ray analysis

Synthesis and structure of N,N′-bis(dihexylphosphorylmethyl)-1,4-diaminobutane

© 2017, Pleiades Publishing, Ltd. N,N′-Bis(dihexylphosphorylmethyl)-1,4-diaminobutane has been obtained via the Kabachnik–Fields reaction. Crystal structure of its salt with nitric acid (bisphosphoryldiammonium dinitrate) has been studied

Synthesis and membrane transport properties of bis(dihexylphosphorylmethyl)-1,4-diaminebutane

© 2016 Taylor & Francis Group, LLC.The membrane-transport properties have been studied. It was found that bis(dihexylphosphorylmethyl)- 1,4-diaminebutane is a good extractant for triply charged metal ions such as Sc(III), Nd(III), and Sm(III). However, it does not exhibit any noticeable selectivity with respect to certain substrates. Bis(dihexylphosphorylmethyl)-1,4-diaminebutane is a good carrier of nitric acid.We have recorded the crystal structure of the complex of the reagent mentioned with the nitric acid

Synthesis, structure, and antimicrobial activity of (carboxyalkyl)dimethylsulfonium halides

© 2017, Pleiades Publishing, Ltd. Reactions of a series of ω-halocarboxylic acids (2-bromo-, 2-chloroethanoic, 3-bromo- and 3-chloropropanoic) with dimethyl sulfide resulted in the formation of stable (carboxylalkyl)dimethylsulfonium bromides and chlorides. Composition and structure of the salts obtained were established by a complex of chemical, physical and physicochemical methods. The sulfonium salts obtained showed high antibacterial and antimycotic activities with respect to the pathogenic microflora of humans and animals

Electron Transfer and Unusual Chemical Transformations of F4-TCNQ in a Reaction with Mn-Phthalocyanine

© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The interaction of manganese phthalocyanine with F4-TCNQ is accompanied by the transformation of the acceptor molecule into a new organic ligand, the 4-(dicyanomethanido)tetra-fluorobenzoate dianion, resulting in the formation of a unique MnIII charge-transfer complex, in which two Mn phthalocyanine moieties are bridged by the dianion, with parallel arrangement of all aromatic fragments and an interplanar distance of 3.30 Å. The formation of the complex takes place in a 2:1 ratio, with the two electrons transferring from two donor molecules to an acceptor molecule. Magnetic measurements reveal that MnIII ions in the studied complex occur in the high-spin state S = 2 and are coupled antiferromagnetically, presumably by the superexchange mechanism through the 4-(dicyanomethanido)tetrafluorobenzoate dianion bridge, with an interaction constant of J = 5 cm–1 (7 K). According to the electrochemical data, the new complex appears to have unusual redox properties and might be described as an electronic reservoir with strong acceptor ability, being able to take seven electrons. Notably, all of the reduction–oxidation steps are reversible, proceeding without structural changes

Synthesis and structure of novel phosphorylated azomethines

© 2016 Taylor & Francis Group, LLC.The condensation of do-, hexa-, octadecan-1-amines with bromo- and nitrobenzaldehydes yielded a series of Schiff bases in good yields. Subsequent reaction of these compounds with dioctylphosphine oxide yielded phosphorylated azomethines and some were characterized using X-ray crystallography. The structure of the isolated compounds was determined by IR and NMR spectroscopy, elemental analysis, and their thermal stability was studied by simultaneous thermogravimetry and differential scanning calorimetry. All of the synthesized compounds were tested for their antibacterial and anti-Candida activity. A number of the compounds exhibited antimicrobial activity comparable to that of the commercially available drugs, ciprofloxacin and clotrimazole

Observation of an Excited Bc+ State

Using pp collision data corresponding to an integrated luminosity of 8.5 fb-1 recorded by the LHCb experiment at center-of-mass energies of s=7, 8, and 13 TeV, the observation of an excited Bc+ state in the Bc+π+π- invariant-mass spectrum is reported. The observed peak has a mass of 6841.2±0.6(stat)±0.1(syst)±0.8(Bc+) MeV/c2, where the last uncertainty is due to the limited knowledge of the Bc+ mass. It is consistent with expectations of the Bc∗(2S31)+ state reconstructed without the low-energy photon from the Bc∗(1S31)+→Bc+γ decay following Bc∗(2S31)+→Bc∗(1S31)+π+π-. A second state is seen with a global (local) statistical significance of 2.2σ (3.2σ) and a mass of 6872.1±1.3(stat)±0.1(syst)±0.8(Bc+) MeV/c2, and is consistent with the Bc(2S10)+ state. These mass measurements are the most precise to date
