Synthesis and Characterization of Nickel(II) Homogeneous and Supported Complexes for the Hydrogenation of Furfural to Furfuryl Alcohol

Nickel(II) complexes have been synthesized and characterized using nuclear magnetic resonance (NMR), infrared spectroscopy, high resolution mass elemental analysis. The were evaluated as pre-catalysts in the direct hydrogenation of furfural to furfuryl alcohol. C1 C4 gave higher conversion (97% 96%, respectively), a result, they also transfer formic acid hydrogen source where (93%) was obtained selectivity (100%) toward formation alcohol at 4 h. catalyst recycled three times with it observed that catalytic activity might be due mixture both molecular catalysis nanoparticles, evidenced by decrease mercury poisoning experiments. reactions extended alpha-β unsaturated substrates selective saturation carbonyl functionality over alkene groups.
