We herein report highly chemoselective transfer hydrogenation of α,β-unsaturated carbonyl compounds to saturated carbonyls with formic acid as a hydrogen donor over a stable and recyclable heterogeneous Pd nanoparticles (NPs) on N,O-dual doped hierarchical porous biomass-derived carbon. The synergistic effect between Pd NPs and incorporated heteroatoms on carbon plays a critical role on promoting the reaction efficiency. A series of α,β-aromatic and aliphatic unsaturated carbonyl compounds was selectively reduced to their corresponding saturated carbonyls in up to 97% isolated yields with good tolerance of various functional groups. In addition, the catalyst can be successively reused for at least 6 times without significant loss in reaction efficiency.

我们在此报告了在N，O-双掺杂分层多孔生物质衍生碳上稳定且可回收的异质Pd纳米颗粒（NPs）上，以甲酸为氢供体，将α，β-不饱和羰基化合物高度化学选择性转移氢化为饱和羰基的方法。Pd NP和掺入的杂原子对碳的协同作用对提高反应效率起关键作用。一系列的α，β-芳族和脂族不饱和羰基化合物被选择性还原为相应的饱和羰基化合物，分离产率高达97％，并具有对各种官能团的良好耐受性。另外，催化剂可以连续重复使用至少6次，而不会显着降低反应效率。
