Для образования НЧ никеля в среде, содержащей 5,0 мМ Ni(NO3)2×6Н2О, оптимальным является 5-кратный избыток NaBH4. На основе поливинилпирролидона (ПВП), гидроксиапатита и алюминиевого порошка сформированы никелевые нанокомпозиты. Обнаружена зависимость морфологии композита (ПВП)Ni от концентрации Ni(NO3)2×6Н2О, что позволяет формировать никелевые частицы разной формы с ПВП носителем.Полученные НЧ никеля и его композиты проявили себя эффективными катализаторами в реакции восстановительного (Na[BH(OAc)3]) аминирования 4-карбметоксибензальдегида N-(2-метил-5-нитрофенил)-4-(пиридил-3-ил)пири-мидин-2-амином с образованием метил 4-{[4-метил-3-(4-(пиридин-3-ил)пиримидин-2-иламино)фениламино]метил} бензоата.</p></abstract><trans-abstract xml:lang="en"><p>Nickel nanoparticles and its composites have been synthesized in a water–DMSO (1:1) mixture by reduction of Ni(NO3)2×6Н2О with sodium tetrahydridoborate. It has been found that, to obtain Ni nanoparticles in 5.0 mM Ni(NO3)2×6Н2О solution, it is best to use 5-fold excess of NaBH4. Nickel nanocomposites have been formed on the basis of polyvinylpyrrolidone (PVP), hydroxyapatite and aluminium powder. The relationship between Ni(NO3)2×6Н2О concentration and (PVP)Ni composite morphology has been established, which allows to form nickel particles of various shapes with a PVP polymeric carrier. These nickel NPs and its composites have proved to be efficient catalysts in the reaction of reductive (Na[BH(OAc)3]) amination of 4-carbomethoxybenzaldehyde with N-(2-methyl)-4-(pyridin-3-yl)pyrimidin-2,5-diamine to give methyl 4-{(4-methyl-3-(4-(5-methylpyridin-3-yl)pyrimidin-2-ylamino)phenylamino)methyl) benzoate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы никеля</kwd><kwd>нанокомпозиты</kwd><kwd>катализаторы</kwd><kwd>восстановительное аминирование</kwd><kwd>произ- водные 2-ариламинопиримидина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel nanoparticles</kwd><kwd>composites</kwd><kwd>catalysts</kwd><kwd>reductive amination</kwd><kwd>2-arylamino pyrimidine derivatives</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">Catalytically Active Borohydride – Reduced Nickel and Cobalt Systems / R.
