[en] A method for preparation of boron dithiophosphinate in the title by means of interaction between 2,4-bis (4-methoxyphenyl)-22,4-dithioxo-1,3,2λ⁵-dithiadiphosphetane and tris (2-bromoethyl borate at 20 deg C for 14 h has been suggested. The product yield amounts to 96%, the product being characterized by the methods of Ir-, NMR- and mass spectroscopy

[en] Using the kinetic method of inhibitors the mechanism is studied of ethane influence on diethylcadmium (R₂Cd) autooxidation by oxygen in toluene at 213-243 K and 0.01-0.1 mol/l R₂Cd concentration. The suggestion was made that the R₂Cd-R₂Cd bimolecular interaction involves a reversible stage of formation of ethane and carbene complex responsible for the generation of chain-leading radicals

[en] Reactions of RuCl₃xnH₂O with hydrochloric hydroxylamine and acetoxime have been studied. It is shown (NH₄)₂[RuNOCl₅] is reaction product in both cases. Possible mechanisms of the reactions are considered. 3 refs

[en] Two methods of metallation of 1,3-diphenyl-2-benzylpropane (DBP) by diphenylytterbium (Ph₂Yb) were tested aimed at developing methods of synthesis of ytterbium organic derivatives containing tribenzylidenmethane dianion. In the first case prepared in advance Ph₂Yb was added to DBP solution in tetrahydrofuran. In the second case Ph₂Yb was prepared in situ by means of interaction between Ph₂Hg and metal ytterbium. It was ascertained that in both cases DBP was transformed into tribenzylidenemethane dianion by action of Ph₂Yb and the relevant organic derivative of ytterbium(II) was formed

[en] A method for preparation of phenylsilane triple labelled with tritium over the Si-H bond was suggested. Reduction of phenyltrichlorosilane with lithium aluminium hydride containing tritium (LiAlT₄) was put in the basis of synthesis of labelled phenylsilane. The yield of the labelled phenylsilane made up approximately 10% (in case of gaseous tritium). The calculated specific activity of the preparation amounted to 80 Ci/mmol, which corresponds to label multiplicity 2.8-2.9

[en] Coordination compounds of rhenium(5) with benzimidazole (L¹) and its derivatives -2-(2-pyridyl)benzimidazole (L²) and 2-mercaptobenzimidazole (L³) of the general formula (HL)₂ [ReOX₅] and [ReOL_xX_y(H₂O)_z]X_k(H₂O)_n, where HL and L - protonated and deprotonated forms of the ligands; X - chloride- and bromide-ions; x, y, z, n, k - stoichiometric coefficients, have been prepared for the first time. Individually of the compounds prepared was confirmed by the results of elementary analysis and IR spectra

[en] Potassium-alumosilicophosphate glass activized by Eu³⁺ has been synthesized, its spectral properties are considered to study the practicability of its application in laser engineering. In Fu³⁺ electron absorption spectrum in the potassium-alumosilicophosphate glass the ⁵D₂ level splits into three sublevels, which permits assuming the hexagonal or trigonal symmetry C_3v of Eu³⁺ nearest surrounding in the glass

[en] A new method of preparation of bis(trifluoroacetyl)iodosoarenes and bis(difluoronitroacetyl)iodosoarenes using a system comprising XeF₂ and 2 equimoles of fluorine-containing acetic acid has been suggested. the reaction was conducted in the medium of methylene chloride at -15 - -10 deg C. After evaporation of the solvent the reaction products were recrystallized from hexane. The reaction yield amounted to 65%. The products were characterized by the methods of chemical analysis. IR spectroscopy and ¹⁹F NMR. 2 refs
