“…Then, substrate FA was used to study the in situ DRIFT adsorption on the catalyst (Figure b). The FA parent spectrum showed a peak at 3245 cm –1 , which was ascribed to O–H groups . It can be seen that the absorption peak of O–H groups on 10Cu5Pd/HY showed an obvious blue shift to 3400 cm –1 , and the intensity and area of the adsorption peak increased significantly compared with the parent peak of FA.…”

It indicates that the O−H groups of FA can be selectively adsorbed on 10Cu5Pd/HY and achieve the preferential conversion of FA to 2-MF.…”

The direct one-pot conversion of furfural to 2-methyltetrahydrofuran (2-MTHF) was investigated in liquid phases using H2 as a hydrogen source over a bimetallic Cu–Pd/HY catalyst. This catalyst showed excellent catalytic reactivity toward the formation of 2-MTHF with a yield of 83.1% under optimized reaction conditions. By adjusting the Cu/Pd ratio in the catalyst, the desired product could be obtained selectively. This was due to (1) selective catalysis of Cu toward C=O bonds in furfural, (2) excellent hydrogenation ability of Pd, and (3) the synergistic effects between Cu, Pd, and the acidic sites of the support HY. The influences of other parameters on conversion and selectivity were also investigated. Mechanism studies revealed that reactions mainly perform through the hydrogenation of furfural to furfuryl alcohol and then hydrodeoxygenation to 2-methylfuran followed by furan ring hydrogenation to 2-MTHF. Finally, after five recycling runs, this catalyst still displayed high catalytic behavior and stability, which provided a certain foundation for future research of furfural catalytic hydrogenation to 2-MTHF.

“…Besides heterogeneous metal-based catalysts, metal phosphides, homogeneous catalysts or transition metal-free catalysts are also of interest. Deng et al 131 demonstrated the potential of metal phosphides by successfully catalyzing the amination of furan alcohols. Shi et al 132 reported an efficient rhodium-catalyzed direct amination of phenols with amines without activating reagents or reductants/oxidants.…”

“…Essentially, β-cyclodextrin acted as a phase transfer catalyst and remained reusable in four subsequent reactions. The biomass-product furan alcohols reacted efficiently with nitrobenzenes over the surface of a bifunctional catalyst, metal phosphides ( Scheme 1 g) [ 27 ]. The catalyst possessed dual active sites namely solid acidic and metallic sites for ring opening, and the abstraction of H from the starting material and the in situ hydrogenation of the nitrobenzenes to anilines.…”

Recent advances in the environmentally benign synthesis of aromatic N-heterocycles are reviewed, focusing primarily on the application of catalytic methods and non-traditional activation. This account features two main parts: the preparation of single ring N-heterocycles, and their condensed analogs. Both groups include compounds with one, two and more N-atoms. Due to the large number of protocols, this account focuses on providing representative examples to feature the available methods.
