Детально исследованы ИК-спектры, в которых наблюдаются изменения параметров полос колебаний связей кремний-кислород, металл-кислород. Для оксида SiO—TiO2 характерно увеличение количества основных центров после удаления L-пролина с поверхности. Композит SiO2—Mg(OH)2*L-пролин повышает значения энантиомерного избытка в асимметрической реакции Биджинелли до 18 %.</p></abstract><trans-abstract xml:lang="en"><p>Individual and mixed oxides of Zn, Mg, Si, Ti, modified with L-proline in the process of sol-gel synthesis, has been obtained. The IR spectra, in which changes in the parameters of vibration bands of the siliconoxygen and metal-oxygen bonds are observed after the removal of L-proline, have been studied in detail. The SiO2-TiO2 oxide is characterized by an increase in the number of basic centers after the removal of L-proline from the surface. The SiO2-Mg(OH)2*L-proline composite increases the values of enantiomeric excess of asymmetric Biginelli reaction product up to 18%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>золь-гель синтез</kwd><kwd>ИК-спектроскопия</kwd><kwd>оксиды кремния</kwd><kwd>цинка</kwd><kwd>магния</kwd><kwd>титана</kwd><kwd>композиты с L-пролином</kwd><kwd>сорбция</kwd><kwd>катализаторы</kwd><kwd>реакция Биджинелли</kwd><kwd>активные центры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sol-gel synthesis</kwd><kwd>IR spectroscopy</kwd><kwd>oxides of silicon</kwd><kwd>zinc</kwd><kwd>magnesium</kwd><kwd>titanium</kwd><kwd>composites with L-proline</kwd><kwd>sorption</kwd><kwd>catalysts</kwd><kwd>Biginelli reaction</kwd><kwd>active centers</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания АААА-А19-119012290117-6 с использованием оборудования Центра коллективного пользования “Спектроскопия и анализ органических соединений” (ЦКП “САОС”).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ю.
