A bisacylphosphine oxide photoinitiator was used for the light mediated preparation of palladium nanoparticles (PdNPs) with a small diameter of 2.8 nm. All starting materials are commercially available, and PdNP synthesis is experimentally very easy to conduct. The PdNP-hybrid material was applied as catalyst for the semihydrogenation of various internal alkynes to provide the corresponding alkenes in excellent yields (up to 99%) and Z-selectivities (Z/E ratios up to 99/1).
一种双膦氧化物光引发剂被用于通过光介导的方法制备钯纳米粒子（PdNPs），其直径小至 2.8nm。所有起始材料均可商购获得，PdNP 的合成在实验上非常容易进行。PdNP 杂化材料被用作各种内部炔烃的半氢化催化剂，以优异的收率（高达 99%）和 Z-选择性（Z/E 比高达 99/1）提供相应的烯烃。
