To study the patterns of behavior of morpholine and its trimethylsilyl derivative in reactions with trimethylsilyl isocyanate.Methods. The study employed infrared and nuclear magnetic resonance spectroscopy, as well as elemental analysis.Results. The formation of mixtures of tautomeric forms of silicon-containing urea—N-(trimethylsilyl) morpholine-4-carboxamide and trimethylsilylmorpholine-4-carboximidoate—was established.Conclusions. It is shown that the composition and structure of the resulting products are determined both by the presence of a morpholine substituent at the nitrogen atom and by the type of isocyanate used. Unlike the trimethylsilyl derivative of morpholine, morpholine itself reacts with trimethylsilyl isocyanate to form a mixture of tautomeric forms.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. Изучить закономерности поведения морфолина и его триметилсилилпроизводного в реакциях с триметилсилилизоцианатом.Методы. В исследовании использовались методы инфракрасной спектроскопии, спектроскопии ядерного магнитного резонанса и элементного анализа.Результаты. Установлено образование смеси таутомерных форм кремнийсодержащей мочевины: N-(триметилсилил)морфолин-4-карбоксамида и триметилсилилморфолин -4-карбоксимидоата.Выводы. Установлено, что состав и строение образующихся продуктов определяется как наличием заместителя при атоме азота морфолина, так и типом используемого изоцианата. Показано, что, в отличие от триметилсилильного производного морфолина, сам морфолин взаимодействует с триметилсилилизоцианатом с образованием смеси таутомерных форм.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морфолин</kwd><kwd>триметилсилилизоцианат</kwd><kwd>кремнийсодержащие мочевины</kwd><kwd>таутомерия</kwd><kwd>амид-изоамидная таутомерия</kwd><kwd>N-(триметилсилил)морфолин4-карбоксамид</kwd><kwd>триметилсилилморфолин-4-карбоксимидоат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>morpholine</kwd><kwd>trimethylsilyl isocyanate</kwd><kwd>silicon-containing ureas</kwd><kwd>tautomerism</kwd><kwd>amideisoamide tautomerism</kwd><kwd>N-(trimethylsilyl)morpholine-4-carboxamide</kwd><kwd>trimethylsilylmorpholine-4-carboxyimidoate</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rakhlin V.I., Tsyrendorzhieva I.P., Sysoev S.V., Rumyantsev Yu.M., Maslova O.V., Kosinova M.L. 4-(Trimethylsilyl)morpholine: synthesis, characterization, and prospects of use in film deposition processes.
