开发了自组装多层铁（0）纳米颗粒（NPs，6-10 nm），即硫修饰的Au负载的Fe（0）[SAFe（0）]，用于无配体的一锅法碳-碳/碳-氮键形成反应。采用一种成熟的金属纳米粒子催化剂制备方法，以1，4-双（三甲基硅基）-1，4-二氢吡嗪（Si-DHP）为强还原剂，通过原位金属纳米粒子和纳米空间组装（PSSO）成功制备了SAFe（0）。SAFe（0）易于在空气中处理，可循环使用，且反应循环中铁浸出率低。
Self-assembled multilayer iron(0) nanoparticles (NPs, 6-10 nm), namely, sulfur-modified Au-supported Fe(0) [SAFe(0)], were developed for ligand-free one-pot carbon-carbon/carbon-nitrogen bond-forming reactions. SAFe(0) was successfully prepared using a well-established metal-nanoparticle catalyst preparative protocol by simultaneous in situ metal NP and nanospace organization (PSSO) with 1,4-bis(trimethylsilyl)-1,4-dihydropyrazine (Si-DHP) as a strong reducing agent. SAFe(0) was easy to handle in air and could be recycled with a low iron-leaching rate in reaction cycles.
