Ru–B nanoparticles on metal–organic frameworks as excellent catalysts for hydrogenation of benzene to cyclohexane under mild reaction conditions

Abstract

Ru–B/MIL-53(AlCr) affords an exceptionally high turnover frequency (TOF) of 6.4 s−1 for hydrogenation of benzene to cyclohexane under mild reaction conditions.

Tiny Ruthenium‐Cobalt‐Cobalt Hydroxide Nanoparticles Supported on Graphene for Efficiently Catalyzing Naphthalene Complete Hydrogenation

“…The catalytic hydrogenation of aromatics plays a significant role in chemical industries . Taking the hydrogenation of naphthalene as an example, the main products are tetralin, octahydronaphthalene and decalin, which have important applications in varnish remover, lubricants, dye, pesticide, pharmaceutical.…”

“…Additionally, tetralin and decalin are often used as efficient solvents for dissolving grease, resin and rubber . Moreover, the redundant existence of arenes in transportation fuels brings environmental damage and the decrease of the cetane number of diesel fuel . Therefore, the depletion of aromatics (eg.…”

“…Therefore, the depletion of aromatics (eg. naphthalene) is of great importance, and the catalytic hydrogenation is the most widely used method of removing aromatics . The development of an efficient catalyst is one of the key factors in this process.…”

Catalytic Hydrogenation of Arenes in Water Over In Situ Generated Ruthenium Nanoparticles Immobilized on Carbon

“…In this regard, the selective hydrogenation of lignin‐derived aromatic compounds to the corresponding alicyclic products is of particular importance . As the functionalisation of cyclohexane is challenging because of the low reactivity of cyclohexane, the synthesis of cyclohexane and its derivatives by the hydrogenation of aromatic precursors attracts extensive scientific and industrial attention . For instance, the chemoselective hydrogenation of benzoic acid to cyclohexanecarboxylic acid has attracted great attention, as the hydrogenated product cyclohexanecarboxylic acid is an important organic intermediate in pharmaceuticals for the synthesis of drugs such as praziquantel and ansatrienin .…”

“…[6][7] As the functionalisation of cyclohexanei sc hallengingb ecause of the low reactivity of cyclohexane, the synthesis of cyclohexane and its derivatives by the hydrogenationo fa romatic precursors attracts extensive scientific and industrial attention. [6,[8][9][10][11][12][13][14][15][16] For instance, the chemoselective hydrogenation of benzoicacid to cyclohexanecarboxylic acid has attracted great attention, as the hydrogenatedp roduct cyclohexanecarboxylic acid is an important organic intermediate in pharmaceuticals for the synthesis of drugs such as praziquantel and ansatrienin. [17] However,t he selective hydrogenation of aromatic rings is challenging, particularly in the presence of several reducible functional groups,b ecause it is an energy-consuming reactiona sar esult of the resonancee nergy of the aromatic ring and the hydrogenation of an aromatic ring is the least preferred in the presence of other reducible functional groups.…”
