Одним из важнейших технологических процессов является окисление циклогексана с получением циклогексанола и циклогексанона. Эти органические вещества имеют особое значение в производстве нейлона, а также как компоненты различных промышленных продуктов. В данной работе описаны синтез и охарактеризование нового мононуклеарного ряда комплексов железа (III) – производных пиперазина, а также представлены результаты испытаний их каталитической активности по отношению к окислению циклогексана. По данным элементного анализа и спектроскопии: ИК-Фурье (FTIR), в ультрафиолетовом и видимом диапазоне (UV-VIS) и Мёссбауэровской спектроскопии каждый комплекс представляет собой октаэдрический высокоспиновый центр железа (III). В результате окисления циклогексана образуются циклогексанол, циклогексанон и циклогексилгидропероксид с выходом до 39 %. Наилучшие результаты были получены с комплексом (NH4)[Fe(BPPZ)Cl2], где BPPZ — лития 1,4-бис-(пропаноат)-пиперазин, и с перекисью водорода в качестве окислителя. Реакции проводили при комнатной температуре и атмосферном давлении, что дает им большое преимущество перед применяемым в настоящее время промышленным способом получения циклогексана.</p></abstract><trans-abstract xml:lang="en"><p>The full article will be published in the English version of the  journal "Catalysis in Industry" No. 4, 2021.</p><p> </p><p>Oxygenated products from selective hydrocarbon oxidation have high commercial value as industrial feedstocks. One of the most important industrial processes is the cyclohexane oxidation to produce cyclohexanol and cyclohexanone. These organic substances have special importance in the Nylon manufacture as well as building blocks for a variety of commercially useful products. In this work we present the synthesis and characterization of a new mononuclear piperazine-derived series of iron(III) complexes and their catalytic activity towards cyclohexane oxidation essays. All complexes present octahedral high-spin iron(III) center according to elemental analysis, FTIR, UV-VIS and Mössbauer spectroscopy characterization. The cyclohexane oxidation resulted in cyclohexanol, cyclohexanone and cyclohexyl hydroperoxide as products, with yields up to 39 %. The best results were obtained with the complex (NH4)[Fe(BPPZ)Cl2] (BPPZ: lithium 1,4-bis-(propanoate) piperazine) and with hydrogen peroxide as oxidant. The reactions were carried out at room temperature and atmospheric pressure, which incomes a great advantage over the current industrial process of cyclohexane production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комплексы негемового железа (III)</kwd><kwd>реакция Михаэля</kwd><kwd>циклогексан</kwd><kwd>окисление</kwd><kwd>катализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>iron(III) non-heme complexes</kwd><kwd>Michael addition</kwd><kwd>cyclohexane</kwd><kwd>oxi7dation</kwd><kwd>catalysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
