- Аннотация: The hydroamination of alkynes is an atomeconomyprocess in the organic synthesis for the C−N bondformation, thereby allowing the production of fine chemicals andintermediates. However, direct interaction between alkynes andamines is complicated due to the electron enrichment of bothcompounds. Therefore, efficient hydroamination catalysts, especiallyheterogeneous ones, are in great demand. This work aimed atthe development of novel heterogeneous catalysts based on zeolitelikemetal−organic frameworks for phenylacetylene hydroamination.The sodalite (SOD) type zeolitic imidazolate framework ZIF-67 (Co(meim)2, meim = 2-methylimidazolate) and boronimidazolate framework BIF-66 ({Co[B(im)4]2}n, im = imidazolate)were studied as the carriers for the gold nanoparticles (Au-NPs). Au-NPs were embedded in the ZIF-67 and BIF-66 matrices byincipient wetness impregnation. Au@ZIF-67 and Au@BIF-66 hybrids were studied for the first time in the liquid phasehydroamination of phenylacetylene with aniline in an air atmosphere and have shown high activity and selectivity in respect to iminein this process. The pronounced impact of the nature of the metal−organic carrier, Au source, and reducing agent on the catalyticperformance of the synthesized nanomaterials was found. To the best of our knowledge, it is the first example of using the zeoliticimidazolate framework and boron-imidazolate framework as the components of the gold-containing catalytic systems for the alkynehydroamination.
