Alcohol amination with heterogeneous ruthenium hydroxyapatite catalysts

Lysinol: a renewably resourced alternative to petrochemical polyamines and aminoalcohols

“…equal mixture of this diastereomeric pair. The results were further confirmed by 19 F NMR evaluation of the products of reaction of enantioenriched and racemic lysinol with R-Mosher acid chloride.…”

C‐N Bond Formation Catalyzed by Ruthenium Nanoparticles Supported on N‐Doped Carbon via Acceptorless Dehydrogenation to Secondary Amines, Imines, Benzimidazoles and Quinoxalines

“…The comparison on the catalytic performances in the N‐alkylation of aniline with benzyl alcohol using Ru/N−C and other known catalysts were listed in Table S2. Ru/N−C presented higher catalytic activity than Cu/Al 2 O 3 (130 °C), Ru/Al 2 O 3 (132 °C), Ru(OH) 3 ‐Fe 3 O 4 (130 °C), Ni/θ−Al 2 O 3 (144 °C) . When the crossing‐coupling reactions were performed at a higher temperature (180 °C), the catalytic activity of Au/TiO 2 was higher than that of Ru/N−C.…”

“…] magnetic NPs, porous organic polymers and metal‐organic‐frameworks (MOFs), and Ru/hydroxyapatite have been successfully employed as catalysts for the assembly of nitrogen‐containing compounds via ADC and ATH methods. Porous carbon‐based materials are effective alternatives as supports because of their extremely high and specific surface areas, controllable porosity and surface chemistry with high stability at various pH values.…”

“…[13] These transformations normally use well-defined ruthenium or iridium organometallic complexes as the catalysts, but these precious organometallic catalysts have not been widely used after their initial reports because of complicated synthesis, recycling problems and potential metal contamination of the products. However, heterogeneous metal nanoparticles (NPs) supported on silica-based materials, [14] metallic oxides, 7 ] magnetic NPs, [16] porous organic polymers [17] and metalorganic-frameworks (MOFs), [18] and Ru/hydroxyapatite [19] have been successfully employed as catalysts for the assembly of nitrogen-containing compounds via ADC and ATH methods. Porous carbon-based materials are effective alternatives as supports [20][21][22] because of their extremely high and specific surface areas, controllable porosity and surface chemistry with high stability at various pH values.…”

Aerobic oxidation of 5-hydroxymethylfurfural into furan compounds over Mo-hydroxyapatite-encapsulated magnetic γ-Fe 2 O 3

“…Hydroxyapatite (HAP) has been attracted much interest due to its structural stability, ionic substitution, and adsorption capacity. More importantly, the Ca 2+ in HAP can be exchanged with other cations, which is a facile method for immobilizing active species [24]. Dioxomolybdenum(VI) complexs are reported to have the ability to catalyze the aerobic oxidation of alcohols.…”
