“…Noble metal-based catalysts afford selective hydroamination of 5-HMF, as well as furfural, with ammonia or aromatic amines to form primary or secondary furfuryl amines. [3,12] In this manner, hydroamination of 5-HMF with the aromatic amines over Pd supported on MOF (UIO-67) led to correspond-ing secondary amines with the yields of 68-96 % at 50 °C and P(H 2 ) = 5 atm. [13] Hydroamination of 5-HMF with aniline over Pd/C catalyst was effective to obtain N-benzylfurfurylamine derivative in quantitative yield under higher temperature (100 °C) and P(H 2 ) = 3 atm.…”

Ceria‐modified mineral‐like copper catalyst 12 %Cu/SiO2−CeO2 showed a high activity and selectivity in one‐pot hydroamination of bio‐available 5‐hydroxymethylfurfural with nitro‐aromatic compounds. The catalyst was obtained by conventional deposition‐precipitation method with urea from commercial silica, copper nitrate, and ammonium cerium (IV) nitrate. The synthesized catalyst with a copper phyllosilicate structure formed inside the pores of silica was studied by XRD, N2 adsorption, XPS, SEM and TEM methods. The possible scheme of 5‐hydroxymethylfurfural hydroamination with nitro‐aromatic compounds and an evolution of the catalyst structure during the reaction were proposed. The catalyst can be successfully recycled after calcination procedure. A number of N‐furfurylamines were obtained for the first time over 12 %Cu/SiO2−CeO2 catalyst with the phyllosilicate structure directly from 5‐hydroxymethylfurfural and nitro‐aromatic compounds with the yields up to 85 %.

“…and nonprecious (Ni, Co, etc.) metals have been developed for catalyzing the reductive amination of furfural to furfurylamine. − However, there still faces a huge challenge in developing highly efficient, selective, and stable catalysts for furfurylamine production because furfurylamine is more nucleophilic than NH 3 , thus it is easy to produce N -furfurylidenefurfurylamine and difurfurylamine. , In addition, furfurin and alcohols can also be produced as byproducts during the reaction. In this context, the development of a highly selective, efficient, stable, and recyclable catalyst for quantitative production of furfurylamine from furfural in the presence of NH 3 and H 2 is an urgent but challenging goal.…”

Highly selective synthesis of primary amines from renewable biomass has attracted increasing attention, but it still faces great challenges in chemical industry applications. In this study, an electron-rich Ru catalyst was constructed by doping N into coffee biochar using a one-pot carbonization method (Ru/NCB-600). Ru/NCB-600 showed high catalytic activity and yield for the reductive amination of furfural with green and cheap NH3 and H2. The excellent catalytic performance of Ru/NCB-600 was closely correlated to the formation of electron-rich Ruδ− species (Ruδ−–N x δ+), which endowed Ru/NCB-600 with an enhanced H2 adsorption and activation ability. Ru/NCB-600 showed a high formation rate of 95.6 gfurfurylamine·gRu –1·h–1 and a high yield of furfurylamine (98.6%) at 50 °C. Ru/NCB-600 can also be used for the reductive amination of various carbonyl compounds in good to excellent yield (95.4–99%). This study thus provides a potential pathway for the highly selective reductive amination of carbonyl compounds by regulating the electron density of Ru.
