Catalytic selective hydrogenation and rearrangement of 5-hydroxymethylfurfural to 3-hydroxymethyl-cyclopentone over a bimetallic nickel–copper catalyst in water
The selective hydrogenation and rearrangement of 5-hydroxymethylfurfural (5-HMF) to 3-hydroxymethyl-cyclopentone (HCPN) were studied over a MOF-derived bimetallic nickel–copper catalyst in water. The combination of nickel and copper dramatically improved the efficiency in both the selective hydrogenation of the carbonyl group of 5-HMF and the hydrogenative ring-rearrangement of the C5 ring, affording
water gave valuable cyclopentenones (4-hydroxy-4-hydroxymethyl-2-cyclopentenone and 4-hydroxy-3-hydroxymethyl-2-cyclopentenone). BHMF was obtained by reduction of 5-hydroxymethylfurfural (5-HMF), which can be easily obtained from common biomass resources. The ratio of the cyclopentenones in the converted mixture can be controllable by adjusting reaction temperature and time. This method would be an environmentally

The valuable 2,5-bis-(hydroxymethyl)tetrahydrofuran useful for the synthesis of surfactants, monomers, and solvents is obtained in high yield from the total hydrogenation of 5-(hydroxymethyl)furfural in a continuous flow reactor in aqueous media using CoNi alloyed nanoparticles covered by a thin carbon layer.
