    名称:
    Unique Catalysis of Nickel Phosphide Nanoparticles to Promote the Selective Transformation of Biofuranic Aldehydes into Diketones in Water
    摘要:
    Although the development of metal nanoparticle catalysts for organic synthesis has been widely studied, the catalytic potential of "metal phosphide nanoparticles" has little been studied. Herein, we describe that nickel phosphide nanoparticles (Ni2P NPs) act as a highly efficient heterogeneous catalyst for the selective transformation of biofuranic aldehydes into diketones, which is a useful biorefining technology. The biofuranic aldehydes are hydrogenated in water without any additives, giving the corresponding diketones in high yields. The catalytic performance of Ni2P NPs demonstrated here is significantly different from conventional Ni(0) and NiO NPs, and other metal phosphide NPs, which show no activity, indicating the unique catalysis of Ni2P NPs. Spectroscopic analyses showed that bifunctional Ni2P NP catalysis combining their hydrogen-activating ability and surface acidity plays a crucial role, leading to the transformations of selective biofuranic aldehydes.

    We report a highly efficient and selective catalytic system, ABNO (9-azabicyclo-[3.3.1]nonane N-oxyl)/HNO3, for the aerobic oxidation of substituted furans to cis-2-ene-1,4-diones under mild reaction conditions using oxygen as the oxidant. The catalyst system is amenable to various substituted (mon-, di-, and tri-) furans and tolerates diverse functional groups, including cyano, nitro, naphthyl, ketone

    mono‐ and bidentate carboxylate bridged compounds, Mn–Mn distances of 1 and 2 are 3,461 Å, and 4,639 Å, respectively. The energy of the compounds was determined with a DFT (Density Functional Theory) calculation on B3LYP/6‐31G(d,p) optimized geometry by using the B3LYP/6‐31G(d,p) basis set. These compounds acts as biomimetic catalyst and show catalase‐like activity for the hydrogen peroxide dismutation

    stability and safety of DMF oxidation were investigated using an ARC. DMF does not react even when the temperature reaches 452 K under nitrogen atmosphere. In oxygen atmosphere, the onset temperature (T0) of DMF oxidation is 323.49 K, and the activation energy (Ea) is 172.35 kJ/mol. The peroxide concentration of oxidation process was determined by iodometry, and the oxidation products were analyzed by
