AgPd nanoshells (AgPd NSs) were used as dual catalysts for hydrogen production and reduction of organic compounds in a one‐pot protocol. AgPd NSs were very efficient catalysts for the reduction of several functional groups, including alkenes, alkynes, imines, nitro compounds, and azides. Excellent chemoselectivities were observed for α,β‐unsaturated ketones, esters, and cinnamonitrile. Also, deuterium‐labeled
AgPd纳米壳(AgPd NSs)用作单反应器中制氢和还原有机化合物的双重催化剂。AgPd NSs是用于还原多个官能团(包括烯烃,炔烃,亚胺,硝基化合物和叠氮化物)的非常有效的催化剂。对于α,β-不饱和酮,酯和肉桂腈,观察到优异的化学选择性。另外,使用D 2 O代替H 2 O制备了氘标记的化合物。设计了包含固定在硅胶中的AgPd NSs(AgPd / SiO 2)的填充床反应器,可在连续流动条件下使用。经过优化的AgPd NSs流动系统能够在30–60分钟的停留时间(t R)。
