По данным спектроскопии ЯМР (1H,13С,15N) полученное соединение представляет собой примерно эквимолекулярную смесь 2-х таутомеров: ожидаемой изотиурониевой соли и хлорида пиридиния с изотиокарбамидным заместителем во 2-м положении. Возможность таутомерного перехода изотиурониевой соли в соль пиридиния определяется наличием 2-х основных центров: атомов азота изотиомочевинового фрагмента и атома азота пиридинового кольца. Квантово-химический анализ методом DFT показывает, что свободные энергии таутомеров оказались близки, при этом протонированный по имидному атому азота таутомер оказался на 2,9 ккал/моль (в газовой фазе) и на 4,7 ккал/моль (при учете растворителя ДМСО на уровне PCM) более выгодным в сравнении с пиридиниевой солью. Небольшая разница в энергиях таутомеров определяет их образование примерно в эквимолекулярном количестве. При быстром прибавлении (5–10 мл/мин) 2-хлорпиридина к раствору тиомочевины в зоне реакции создается избыток реагента, который, воздействуя как основание, провоцирует расщепление изотиурониевой соли, что приводит к дополнительному образованию в реакционной среде бис(2-пиридил)сульфида – ценного лиганда для получения координационных соединений. Синтезированная смесь таутомеров была исследована в качестве добавки в стандартный электролит никелирования. В концентрации 0,3–0,5 г/л добавка обеспечивала получение блестящих низкопористых никелевых покрытий при достаточно высокой плотности тока 5–10 А/дм2 с выходом по току 98–99 %.</p></abstract><trans-abstract xml:lang="en"><p>The synthesis and spectral characterisation of 2-pyridylisothiuronium chloride were performed by regulating the rate of feeding 2-chloropyridine into a thiourea solution in ethyl alcohol for ensuring its low concentration in the reaction zone. According to the data of NMR spectroscopy (1H,13С,15N), the obtained compound represents an approximately equimolar mixture of two tautomers: the expected isothiuronium salt and pyridinium chloride with an isothiocarbamide substituting group in the 2nd position. The ability of isothiuronium salt to transit tautomerically to pyridinium salt is determined by the presence of two main centres, including nitrogen atoms of the isothiourea unit and a nitrogen atom of the pyridine ring. A quantum chemical analysis performed using the DFT method showed that the free energy values of the tautomers were similar, with the tautomer protonated on the nitrogen imido-atom being 2.9 (in the gas phase) and 4.7 kcal/mole (taking into account the dimethyl sulphoxide solvent DMSO at the PCM level) more advantageous as compared to the pyridinium salt. A small difference in the tautomer energies determines their formation in an approximately equimolar quantity. A rapid addition (5–10 mL/min) of 2-chloropyridine to the thiourea solution in the reaction zone creates the surplus of the reagent, acting as a base and causing splitting of the isotiuronium salt. This leads to an additional formation of bis(2-pyridyl)sulphide in the reaction medium, representing a valuable ligand for obtaining coordination compounds. The synthesised mixture of tautomers was examined as an additive to the standard nickel-plating electrolyte. In the concentration of 0.3–0.5 g/L, this additive ensured the production of bright low-porous nickel coatings at a sufficiently high current density of 5–10 A/dm2 and a current yield of 98–99 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>2-хлорпиридин</kwd><kwd>изотиурониевая соль</kwd><kwd>таутомерия</kwd><kwd>квантово-химический расчет</kwd><kwd>бис(2-пиридил)сульфид</kwd><kwd>блестящее никелирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>2-chloropyridine</kwd><kwd>isothiuronium salt</kwd><kwd>tautomerism</kwd><kwd>quantum chemical calculation</kwd><kwd>bis(2-pyridyl) sulphide</kwd><kwd>bright nickel plating</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Спектральные и аналитические данные были получены с использованием оборудования Байкальского аналитического центра коллективного пользования Иркутского института химии им.
