hydrogenation catalyzed heterogeneously by palladium on boron nitride (Pd/BN) in methanol realized the chemoselective hydrogenation of only azides, alkenes, and alkynes in the presence of other reducible functionalities such as benzyl ethers, aryl halides, aryl ketones, and nitro groups. Furthermore, the totally chemoselective semihydrogenation of alkynes could also be achieved without the reduction
钯在甲醇中的氮化硼(Pd / BN)上的异相催化氢化反应仅在存在其他可还原官能团(例如苄基醚,芳基卤化物,芳基酮和硝基)的情况下,仅对叠氮化物,烯烃和炔烃进行化学选择性氢化。此外,通过在吡啶中使用Pd / BN作为溶剂,还可以在不降低其他共存的可还原官能度(包括叠氮化物和烯烃)的情况下,实现炔烃的完全化学选择性半氢化反应。
