Abstract

Core-shell nanocatalysts are attractive due to their versatility and stability. Here, we describe cobalt nanoparticles encapsulated within graphitic shells prepared via the pyrolysis of a cationic poly-ionic liquid (PIL) with a cobalt(II) chloride anion. The resulting material has a core-shell structure that displays excellent activity and selectivity in the self-dehydrogenation and hetero-dehydrogenation of primary amines to their corresponding imines. Furthermore, the catalyst exhibits excellent activity in the synthesis of secondary imines from substrates with various reducible functional groups (C=C, C≡C and C≡N) and amino acid derivatives.

摘要

核壳纳米催化剂因其多功能性和稳定性而备受关注。在此，我们描述了通过阳离子聚离子液体（PIL）与氯化钴阴离子热解制备的包裹在石墨壳内的钴纳米颗粒。所得材料具有核壳结构，在伯胺自脱氢和异脱氢生成相应亚胺的反应中表现出优异的活性和选择性。此外，该催化剂在由具有各种可还原官能团（C=C、C≡C和C≡N）的底物和氨基酸衍生物合成仲亚胺的反应中表现出优异的活性。
