- Аннотация: New methods for the preparation of metal–organic frameworks UiO-66 and NH2-UiO-66 with a hierarchical porous structure were developed using the MW-assisted technique underatmospheric pressure. The synthesized nanostructured meso-UiO-66 and meso-NH2-UiO-66 matriceswere utilized as Au nanoparticle carriers. The resulting Au@meso-UiO-66 and Au@NH2-UiO-66nanohybrids were studied in the reaction of phenylacetylene hydroamination with aniline into imine([phenyl-(1-phenylethylydene)amine]) for the first time. Their catalytic behavior is significantlydetermined by a combination of factors, such as a small crystal size, micro–mesoporous structure,and functionality of the UiO-66 and NH2-UiO-66 carriers, as well as a high dispersion of embeddedgold nanoparticles. The Au@meso-UiO-66 and Au@NH2-UiO-66 nanocatalysts demonstrate highactivities (TOF), with conversion and selectivity values over 90. This excellent catalytic performance iscomparable or even better than that demonstrated by heterogeneous systems based on conventionalinorganic and inorganic supports known from the literature.
