Разработаны методы получения нанокомпозитов модифицированного ультрадисперсного алмаза детонационного синтеза с металлическим палладием и изучена их каталитическая активность в реакции кросс-сочетания Сузуки-Мияуры в различных реакционных средах. Исследованы методики регенерации палладийсодержащих нанокомпозитов из реакционной смеси. Каталитическая активность нанокомпозитов подтверждена исследованием кинетики реакции кросс-сочетания хроматографическим анализом реакционной смеси и сопоставима с уже используемыми подобными катализаторами. Регенерированные нанокомпозиты показали сохранение каталитической активности для 3 последовательных циклов кросс-сочетания на модельных системах.

Methods for preparation of nanocomposites of modified detonation nanodiamonds (DND) with metallic palladium have been developed and their catalytic activity in the Suzuki-Miyaura cross-coupling reaction in various reaction media has been studied. Methods for the regeneration of palladium-containing nanocomposites from the reaction mixture have been developed. The high catalytic activity of nanocomposites is confirmed by kinetic analysis based on the results of chromatographic analysis of the reaction mixture and is comparable to the literature data about similar catalytic systems. Regenerated nanocomposites showed the retention of catalytic activity for 3 consecutive cross-coupling cycles on model systems.
